# Content Extraction Logic Analysis - ai.process Action
|
|
|
|
## Overview
|
|
This document provides a stepwise structured analysis of the content extraction logic in the main AI call (`ai.process` action). It covers input formats, document processing, AI service communication, and content handling.
|
|
|
|
---
|
|
|
|
## 1. Input Content Formats
|
|
|
|
### 1.1 Document Input Formats
|
|
The `ai.process` action accepts documents in the following formats:
|
|
|
|
#### Supported Document Types (via Extraction Service)
|
|
- **PDF** (`application/pdf`) - Extracted via `PdfExtractor`
|
|
- **Word Documents** (`application/vnd.openxmlformats-officedocument.wordprocessingml.document`) - Extracted via `DocxExtractor`
|
|
- **Excel** (`application/vnd.openxmlformats-officedocument.spreadsheetml.sheet`) - Extracted via `XlsxExtractor`
|
|
- **PowerPoint** (`application/vnd.openxmlformats-officedocument.presentationml.presentation`) - Extracted via `PptxExtractor`
|
|
- **CSV** (`text/csv`) - Extracted via `CsvExtractor`
|
|
- **HTML** (`text/html`) - Extracted via `HtmlExtractor`
|
|
- **XML** (`application/xml`, `text/xml`) - Extracted via `XmlExtractor`
|
|
- **JSON** (`application/json`) - Extracted via `JsonExtractor`
|
|
- **Images** (`image/jpeg`, `image/png`, `image/gif`, `image/webp`) - Extracted via `ImageExtractor`
|
|
- **Text** (`text/plain`) - Extracted via `TextExtractor`
|
|
- **SQL** (`application/sql`) - Extracted via `SqlExtractor`
|
|
- **Binary** (other formats) - Extracted via `BinaryExtractor`
|
|
|
|
#### Document Reference Formats
|
|
Documents are provided via the `documentList` parameter which accepts:
|
|
- `DocumentReferenceList` object (preferred)
|
|
- List of strings (document references)
|
|
- Single string (single document reference)
|
|
- `None` (no documents)
|
|
|
|
### 1.2 Content Parts Input Format
|
|
Alternatively, pre-extracted content can be provided via `contentParts` parameter:
|
|
- **Type**: `List[ContentPart]`
|
|
- **ContentPart Structure**:
|
|
```python
|
|
ContentPart(
|
|
id: str, # Unique identifier
|
|
parentId: Optional[str], # Parent part ID (for hierarchical content)
|
|
label: str, # Human-readable label
|
|
typeGroup: str, # "text", "table", "image", "structure", "container", "binary"
|
|
mimeType: str, # MIME type of the content
|
|
data: Union[str, bytes], # Actual content data
|
|
metadata: Dict[str, Any] # Metadata including:
|
|
# - documentId
|
|
# - documentMimeType
|
|
# - originalFileName
|
|
# - contentFormat ("extracted", "object", "reference")
|
|
# - intent ("extract", "display", "analyze")
|
|
# - usageHint
|
|
# - extractionPrompt
|
|
# - sourceAction
|
|
)
|
|
```
|
|
|
|
### 1.3 Prompt Input Format
|
|
- **Type**: `str`
|
|
- **Required**: Yes
|
|
- **Description**: Instruction for the AI describing what processing to perform
|
|
|
|
### 1.4 Result Type Format
|
|
- **Type**: `str`
|
|
- **Default**: `"txt"`
|
|
- **Supported Formats**: `txt`, `json`, `md`, `csv`, `xml`, `html`, `pdf`, `docx`, `xlsx`, `pptx`, `png`, `jpg`, `jpeg`, `gif`, `webp`
|
|
- **Purpose**: Determines output file extension and generation intent
|

## 2. Document Processing Flow
|
|
|
|
### 2.1 Entry Point: `ai.process` Action
|
|
**Location**: `gateway/modules/workflows/methods/methodAi/actions/process.py`
|
|
|
|
**Flow**:
|
|
1. **Parameter Extraction** (lines 35-55)
|
|
- Extract `aiPrompt` from parameters
|
|
- Extract `documentList` and convert to `DocumentReferenceList`
|
|
- Extract `resultType` (default: "txt")
|
|
- Extract `contentParts` if already provided
|
|
|
|
2. **Content Extraction Decision** (lines 72-119)
|
|
- **Path A**: If `contentParts` already provided → Skip extraction, use provided parts
|
|
- **Path B**: If `documentList` provided but no `contentParts` → Extract content from documents
|
|
- **Path C**: If BOTH `contentParts` AND `documentList` provided:
|
|
- **In `ai.process` action** (lines 85-86, 167-174):
|
|
- Condition: `if not contentParts and documentList.references:` (line 86)
|
|
- **Behavior**: Only extracts from `documentList` if `contentParts` is NOT provided
|
|
- **Result**: If both provided, `contentParts` takes precedence
|
|
- **Important**: `documentList` is **NOT passed** to `callAiContent()` (line 167)
|
|
- Only `contentParts` is passed to the AI service
|
|
- **Conclusion**: `documentList` is **ignored** when `contentParts` is provided
|
|
- **Note**: Merging logic exists in document generation path (`DocumentGenerationPath.generateDocument`, lines 109-119), but this only applies when `documentList` is passed separately to `callAiContent()` (not from `ai.process` action)
|
|
- **Note**: Similar merging exists in data extraction path (`_handleDataExtraction`, lines 727-733), but also requires `documentList` to be passed to `callAiContent()`
|
|
|
|
### 2.2 Content Extraction Process (Path B)
|
|
|
|
**Location**: `gateway/modules/services/serviceExtraction/mainServiceExtraction.py`
|
|
|
|
#### Step 1: Document Resolution (lines 86-94 in process.py)
|
|
```python
|
|
chatDocuments = self.services.chat.getChatDocumentsFromDocumentList(documentList)
|
|
```
|
|
- Converts `DocumentReferenceList` to `List[ChatDocument]`
|
|
- Each `ChatDocument` contains:
|
|
- `id`: Document ID
|
|
- `fileId`: File ID for database lookup
|
|
- `fileName`: Original filename
|
|
- `mimeType`: MIME type
|
|
|
|
#### Step 2: Extraction Options Preparation (lines 96-108 in process.py)
|
|
```python
|
|
extractionOptions = ExtractionOptions(
|
|
prompt="Extract all content from the document",
|
|
mergeStrategy=MergeStrategy(
|
|
mergeType="concatenate",
|
|
groupBy="typeGroup",
|
|
orderBy="id"
|
|
),
|
|
processDocumentsIndividually=True
|
|
)
|
|
```
|
|
|
|
#### Step 3: Content Extraction (line 111 in process.py)
|
|
```python
|
|
extractedResults = self.services.extraction.extractContent(chatDocuments, extractionOptions)
|
|
```
|
|
|
|
**Extraction Service Flow** (`mainServiceExtraction.py:extractContent`):
|
|
|
|
1. **For each document** (lines 69-288):
|
|
- **Load document bytes** (line 96):
|
|
```python
|
|
documentBytes = dbInterface.getFileData(doc.fileId)
|
|
```
|
|
|
|
- **Run extraction pipeline** (lines 113-120):
|
|
```python
|
|
ec = runExtraction(
|
|
extractorRegistry=self._extractorRegistry,
|
|
chunkerRegistry=self._chunkerRegistry,
|
|
documentBytes=documentData["bytes"],
|
|
fileName=documentData["fileName"],
|
|
mimeType=documentData["mimeType"],
|
|
options=options
|
|
)
|
|
```
|
|
|
|
- **Extraction Process**:
|
|
- **Extractor Selection**: Based on MIME type, select appropriate extractor (PDF, DOCX, XLSX, etc.)
|
|
- **Content Parsing**: Extractor parses document and extracts structured content
|
|
- **Chunking** (if needed): Large content is chunked based on size limits
|
|
- **ContentPart Creation**: Each extracted piece becomes a `ContentPart` with:
|
|
- `typeGroup`: "text", "table", "image", "structure", "container", "binary"
|
|
- `data`: Extracted content (text, table data, base64 image, etc.)
|
|
- `mimeType`: Original MIME type
|
|
- `label`: Descriptive label
|
|
|
|
- **Metadata Attachment** (lines 132-166):
|
|
```python
|
|
# Required metadata fields
|
|
p.metadata["documentId"] = documentData["id"]
|
|
p.metadata["documentMimeType"] = documentData["mimeType"]
|
|
p.metadata["originalFileName"] = documentData["fileName"]
|
|
p.metadata["contentFormat"] = "extracted" # Default
|
|
p.metadata["intent"] = "extract" # Default
|
|
p.metadata["extractionPrompt"] = options.prompt
|
|
p.metadata["usageHint"] = f"Use extracted content from {documentData['fileName']}"
|
|
p.metadata["sourceAction"] = "extraction.extractContent"
|
|
```
|
|
|
|
2. **Return Results**:
|
|
- Returns `List[ContentExtracted]` (one per input document)
|
|
- Each `ContentExtracted` contains:
|
|
- `id`: Document ID
|
|
- `parts`: `List[ContentPart]` - All extracted content parts
|
|
|
|
#### Step 4: Combine ContentParts (lines 113-119 in process.py)
|
|
```python
|
|
contentParts = []
|
|
for extracted in extractedResults:
|
|
if extracted.parts:
|
|
contentParts.extend(extracted.parts)
|
|
```
|
|
|
|
**Result**: Single `List[ContentPart]` containing all extracted content from all documents.
|

|
|

## 4. What the AI Service Does with Documents and Contents
|
|
|
|
### 4.1 AI Service Entry Point
|
|
**Location**: `gateway/modules/services/serviceAi/mainServiceAi.py:callAiContent` (line 540)
|
|
|
|
### 4.2 Operation Type Routing
|
|
|
|
#### 4.2.1 IMAGE_GENERATE (lines 599-601)
|
|
- Routes to `_handleImageGeneration()`
|
|
- Generates images from prompt (no document processing)
|
|
|
|
#### 4.2.2 DATA_GENERATE (lines 607-640)
|
|
- **Requires**: `generationIntent` parameter
|
|
- **Routes based on intent**:
|
|
- `generationIntent == "code"` → `_handleCodeGeneration()`
|
|
- `generationIntent == "document"` → `_handleDocumentGeneration()`
|
|
|
|
#### 4.2.3 DATA_EXTRACT (lines 643-653)
|
|
- Routes to `_handleDataExtraction()`
|
|
- Extracts content from documents, then processes with AI
|
|
|
|
### 4.3 Document Generation Flow (`_handleDocumentGeneration`)
|
|
|
|
**Location**: `mainServiceAi.py:_handleDocumentGeneration` (referenced at line 631)
|
|
|
|
**CRITICAL**: When called from `ai.process` action:
|
|
- **Only `contentParts` is passed** to `callAiContent()` (line 167 in `process.py`)
|
|
- **`documentList` is NOT passed** (it's `None`)
|
|
- Therefore, **extraction does NOT happen again** in the document generation path
|
|
- The `contentParts` already extracted in `ai.process` are used directly
|
|
- **Steps 1-2 below are SKIPPED** for `ai.process` flow (no `documentList` to process)
|
|
|
|
**Note**: `DocumentGenerationPath.generateDocument()` can also be called directly from other code paths with `documentList`, so it handles both cases. The following steps describe the general flow when `documentList` IS provided (not from `ai.process`).
|
|
|
|
#### Step 1: Document Intent Clarification
|
|
- **Condition**: `if documentList:` AND `documentIntents` not provided
|
|
- If documents exist:
|
|
- Calls `clarifyDocumentIntents()` to analyze document purposes
|
|
- Determines how each document should be used (extract, display, analyze)
|
|
- **For `ai.process` flow**: This step is **skipped** (no `documentList` passed)
|
|
|
|
#### Step 2: Content Extraction and Preparation
|
|
- **Condition**: `if documents:` (i.e., if `documentList` was provided and converted to documents)
|
|
- If documents exist:
|
|
- Calls `extractAndPrepareContent()`:
|
|
- **RAW Extraction (NO AI)**: Uses `extractContent()` service for pure document parsing
|
|
- **What it does**: Parses PDF, DOCX, XLSX, etc. to extract structured content
|
|
- **What it creates**: ContentParts with raw extracted data
|
|
- **AI involved**: NONE - this is pure parsing/parsing, no AI calls
|
|
- **Prompt Used**: `intent.extractionPrompt` or default `"Extract all content from the document"`
|
|
- **Important**: This prompt is stored in metadata but NOT used for AI extraction here
|
|
- It's only used later during section generation (Step 4) for Vision AI extraction
|
|
- **Purpose**: Just metadata storage, not actual AI prompt execution
|
|
- **ContentPart Preparation**:
|
|
- **For Images**:
|
|
- Creates image ContentPart with base64 image data
|
|
- Marks with `needsVisionExtraction: True`
|
|
- Stores `extractionPrompt` in metadata for later use
|
|
- **Reason**: Vision AI extraction is expensive, so it's deferred to section generation
|
|
- **No AI extraction happens here** - image is just parsed and stored
|
|
- **For Text**:
|
|
- Creates text ContentPart with extracted text (from PDF text layer, DOCX text, etc.)
|
|
- Marks with `skipExtraction: True` (already extracted from parsing, no AI needed)
|
|
- **No AI extraction happens here** - text is already extracted from document parsing
|
|
- **For Objects**: Creates object ContentParts for rendering (images, videos, etc.)
|
|
- Then merges with provided `contentParts` (if any)
|
|
- **For `ai.process` flow**: This step is **skipped** (no `documentList` passed, `contentParts` already extracted)
|
|
- **Why Extract (Parse) Before Structure Generation?**
|
|
- **ContentParts are needed BEFORE structure generation** so AI can assign them to chapters
|
|
- Structure generation needs to know:
|
|
- What documents exist (documentId)
|
|
- What content types are available (typeGroup: text, image, table, etc.)
|
|
- What content formats exist (contentFormat: extracted, object, reference)
|
|
- **Structure generation doesn't need AI-extracted text from images** - it just needs to know images exist
|
|
- Vision AI extraction (converting images to text) is deferred to section generation (Step 4) for efficiency
|
|
- **Key Point**: Only RAW parsing happens here - NO AI calls, NO Vision AI, NO text extraction from images
|
|
|
|
#### Step 3: Structure Generation (for document formats)
|
|
- Calls `structureGenerator.generateStructure()`:
|
|
- Generates document structure (chapters, sections)
|
|
- Creates JSON structure with:
|
|
- `metadata`: Title, language
|
|
- `documents`: Array of document structures
|
|
- `chapters`: Array of chapter structures with:
|
|
- `id`, `level`, `title`
|
|
- `contentParts`: Assignment of ContentParts to chapters
|
|
- `generationHint`: Description of chapter content
|
|
|
|
#### Step 4: Structure Filling
|
|
- Calls `structureFiller.fillStructure()`:
|
|
- For each chapter:
|
|
- Extracts relevant ContentParts assigned to chapter
|
|
- **Vision AI Extraction (if needed)**:
|
|
- Checks for ContentParts with `needsVisionExtraction == True` (images)
|
|
- Calls Vision AI with `extractionPrompt` from metadata (line 651 in `subStructureFilling.py`)
|
|
- Converts image ContentPart to text ContentPart with extracted text
|
|
- **Prompt Used**: `part.metadata.get("extractionPrompt")` or default `"Extract all text content from this image..."`
|
|
- **Section Generation**:
|
|
- Generates section content using AI with processed ContentParts
|
|
- Processes ContentParts with model-aware chunking if needed
|
|
- Merges results intelligently
|
|
- **Two-Phase Extraction Explained**:
|
|
- **Phase 1 (Step 2)**: RAW extraction (parsing) - creates ContentParts for structure generation
|
|
- **Phase 2 (Step 4)**: Vision AI extraction (for images only) - happens during section generation
|
|
- **Why Two Phases?**
|
|
- Structure generation needs ContentParts early (to assign to chapters)
|
|
- Vision AI extraction is expensive and only needed when generating content
|
|
- Text content doesn't need AI extraction (already extracted in Phase 1)
|
|
|
|
#### Step 5: Document Rendering
|
|
- Converts filled structure to final document format (PDF, DOCX, XLSX, etc.)
|
|
- Returns `AiResponse` with rendered documents
|
|
|
|
### 4.4 Content Parts Processing (`processContentPartsWithAi`)
|
|
|
|
**Location**: `gateway/modules/services/serviceExtraction/mainServiceExtraction.py:processContentPartsWithAi` (line 1499)
|
|
|
|
#### Step 1: Model Selection
|
|
```python
|
|
availableModels = modelRegistry.getAvailableModels()
|
|
failoverModelList = modelSelector.getFailoverModelList(prompt, "", options, availableModels)
|
|
```
|
|
- Selects appropriate AI models based on:
|
|
- Operation type
|
|
- Content type (text, images, etc.)
|
|
- Model capabilities
|
|
|
|
#### Step 2: Parallel Processing
|
|
- Processes all ContentParts in parallel (max 5 concurrent by default)
|
|
- For each ContentPart:
|
|
- Calls `processContentPartWithFallback()`
|
|
|
|
#### Step 3: ContentPart Processing (`processContentPartWithFallback`)
|
|
|
|
**Location**: `mainServiceExtraction.py:processContentPartWithFallback` (line 1232)
|
|
|
|
**Flow**:
|
|
|
|
1. **Size Check** (lines 1328-1379):
|
|
```python
|
|
# Calculate if content fits in model context
|
|
partSize = len(contentPart.data.encode('utf-8'))
|
|
modelContextTokens = model.contextLength
|
|
availableContentTokens = int((modelContextTokens - totalReservedTokens) * 0.8)
|
|
```
|
|
|
|
2. **Chunking Decision**:
|
|
- If content exceeds model limits → **Chunk content**
|
|
- If content fits → **Process directly**
|
|
|
|
3. **Chunking Process** (`chunkContentPartForAi`, line 1146):
|
|
- Calculates model-specific chunk sizes:
|
|
```python
|
|
# Reserve tokens for:
|
|
# - Prompt
|
|
# - System message wrapper
|
|
# - Max output tokens
|
|
# - Message overhead
|
|
availableContentTokens = int((modelContextTokens - totalReservedTokens) * 0.60)
|
|
```
|
|
- Uses appropriate chunker based on `typeGroup`:
|
|
- `TextChunker` for text
|
|
- `StructureChunker` for JSON/structured content
|
|
- `TableChunker` for tables
|
|
- `ImageChunker` for images
|
|
|
|
4. **AI Call**:
|
|
- **For chunks**: Process each chunk separately, then merge results
|
|
- **For single part**: Call AI directly
|
|
- **For images**: Special handling with vision models (base64 encoding)
|
|
|
|
5. **Model Fallback**:
|
|
- If model fails → Try next model in failover list
|
|
- Continues until success or all models exhausted
|
|
|
|
#### Step 4: Result Merging (`mergePartResults`)
|
|
|
|
**Location**: `mainServiceExtraction.py:mergePartResults` (line 615)
|
|
|
|
**Merging Strategies**:
|
|
|
|
1. **Elements Response Format** (detected at line 657):
|
|
- Merges JSON responses with `"elements"` array
|
|
- Specifically merges tables by headers
|
|
- Combines rows from tables with same headers
|
|
|
|
2. **JSON Extraction Response Format** (detected at line 669):
|
|
- Merges `{"extracted_content": {...}}` structures
|
|
- Combines:
|
|
- Text blocks
|
|
- Tables (by headers)
|
|
- Headings
|
|
- Lists
|
|
- Images
|
|
|
|
3. **Regular Merging** (line 680):
|
|
- Uses `MergeStrategy`:
|
|
- `groupBy`: "typeGroup" or "documentId"
|
|
- `orderBy`: "id" or "originalIndex"
|
|
- `mergeType`: "concatenate"
|
|
- Applies intelligent token-aware merging if enabled
|
|
- Preserves ContentPart metadata
|
|
|
|
#### Step 5: Return Merged Content
|
|
- Returns single `AiCallResponse` with:
|
|
- `content`: Merged content string
|
|
- `modelName`: "multiple" (if multiple models used)
|
|
- `priceUsd`: Sum of all model costs
|
|
- `processingTime`: Sum of all processing times
|
|
- `bytesSent`: Sum of all bytes sent
|
|
- `bytesReceived`: Sum of all bytes received

## 7. Important Notes
|
|
|
|
### 7.1 Content Extraction Separation
|
|
- **Extraction** (no AI): Pure document parsing and content extraction
|
|
- **AI Processing**: Content analysis, generation, transformation
|
|
|
|
### 7.2 Model-Aware Chunking
|
|
- Chunking considers:
|
|
- Model context length
|
|
- Model max output tokens
|
|
- Prompt size
|
|
- System message overhead
|
|
- Conservative safety margins (60% of available tokens)
|
|
|
|
### 7.3 Parallel Processing
|
|
- ContentParts are processed in parallel (max 5 concurrent)
|
|
- Improves performance for multiple documents/parts
|
|
|
|
### 7.4 Intelligent Merging
|
|
- Merges content intelligently:
|
|
- Tables by headers
|
|
- Text blocks with separators
|
|
- Preserves document structure
|
|
- Token-aware optimization
|
|
|
|
### 7.5 Metadata Preservation
|
|
- ContentPart metadata is preserved throughout the pipeline
|
|
- Includes document source, extraction prompt, usage hints
|
|
- Enables traceability and proper content assignment
|
|

|
## 8. Debug Files Generated
|
|
|
|
During processing, the following debug files may be generated:
|
|
|
|
1. **Extraction Results**: `extraction_result_{filename}.txt`
|
|
- Contains extraction summary per document
|
|
- Includes part metadata and data previews
|
|
|
|
2. **Text Parts**: `extraction_text_part_{N}_{filename}.txt`
|
|
- Contains full extracted text for each text part
|
|
|
|
3. **Per-Part Extracted Data**: `content_extraction_per_part.txt`
|
|
- Contains per-part extracted content summary
|
|
|
|
4. **Original Parts Extracted Data**: `content_extraction_original_parts.txt`
|
|
- Contains original parts with extracted content
|
|
|
|
5. **Generation Prompts/Responses**: `generation_contentPart_{id}_{label}_{prompt|response}.txt`
|
|
- Contains prompts and responses for generation phase
|
|
|
|
6. **Structure Generation**: `chapter_structure_generation_{prompt|response}.txt`
|
|
- Contains structure generation prompts and responses
|

## 9. Recommendations and Next Steps
|
|
|
|
This section documents architectural findings, recommendations, and planned improvements. Topics will be added step by step as analysis progresses.
|
|
|
|
### 9.1 Architectural Inconsistency: contentParts + documentList Merging Behavior
|
|
|
|
#### Problem Statement
|
|
|
|
The `ai.process` action exhibits **inconsistent behavior** when both `contentParts` and `documentList` parameters are provided:
|
|
|
|
**Current Behavior Across Code Paths:**
|
|
|
|
1. **`ai.process` Action** (`process.py` lines 85-86):
|
|
- **Logic**: `if not contentParts and documentList.references:`
|
|
- **Behavior**: If both provided → Only `contentParts` used, `documentList` ignored
|
|
- **Issue**: `documentList` is not passed to `callAiContent()`, so it's completely ignored
|
|
|
|
2. **Document Generation Path** (`documentPath.py` lines 109-119):
|
|
- **Logic**: Extracts from `documentList`, then merges with `contentParts`
|
|
- **Behavior**: If both provided → **MERGES** both
|
|
- **Code**: `preparedContentParts.extend(contentParts)`
|
|
|
|
3. **Data Extraction Path** (`mainServiceAi.py` lines 727-733):
|
|
- **Logic**: Extracts from `documentList`, then merges with `contentParts`
|
|
- **Behavior**: If both provided → **MERGES** both
|
|
- **Code**: `preparedContentParts.extend(contentParts)`
|
|
|
|
#### Analysis
|
|
|
|
**Arguments FOR Current Behavior (Skip documentList):**
|
|
- Performance: Avoids redundant extraction if contentParts already provided
|
|
- Explicit Intent: If user provides contentParts, they may want only those
|
|
- Pre-extracted Content: contentParts might be pre-processed/filtered content
|
|
- Simplicity: Simpler logic, fewer edge cases
|
|
|
|
**Arguments AGAINST Current Behavior (Should Merge):**
|
|
- **Inconsistency**: Other paths merge, creating confusion
|
|
- **User Intent**: If user provides both, they likely want both used
|
|
- **Flexibility**: Allows combining pre-extracted content with additional documents
|
|
- **Architectural Pattern**: Document generation path already handles this correctly
|
|
- **No Performance Issue**: Extraction is fast, merging is trivial
|
|
|
|
#### Recommendation
|
|
|
|
**The current behavior in `ai.process` does NOT make architectural sense** because:
|
|
|
|
1. **Inconsistency**: The action routes to paths that DO merge, but the action itself doesn't
|
|
2. **Lost Functionality**: User cannot combine pre-extracted contentParts with additional documents
|
|
3. **Unexpected Behavior**: Users might expect both to be used (like in other paths)
|
|
|
|
#### Proposed Fix
|
|
|
|
Change `ai.process` to merge both with intelligent deduplication:
|
|
|
|
**Logic Requirements:**
|
|
- Extract content parts from documents (without AI) **only if** that document is not already represented in the `contentParts` list
|
|
- Merge all contentParts
|
|
- Result: Complete list of contentParts for all provided documents (no duplicates)
|
|
|
|
**Current Implementation** (lines 85-119):
|
|
```python
|
|
# If contentParts not provided but documentList is, extract content first
|
|
if not contentParts and documentList.references:
|
|
# Extract from documentList
|
|
extractedResults = self.services.extraction.extractContent(...)
|
|
contentParts = []
|
|
for extracted in extractedResults:
|
|
if extracted.parts:
|
|
contentParts.extend(extracted.parts)
|
|
```
|
|
|
|
**Proposed Implementation**:
|
|
```python
|
|
# Step 1: Identify documents already represented in contentParts
|
|
documentsAlreadyExtracted = set()
|
|
if contentParts:
|
|
for part in contentParts:
|
|
documentId = part.metadata.get("documentId")
|
|
if documentId:
|
|
documentsAlreadyExtracted.add(documentId)
|
|
logger.info(f"Found {len(documentsAlreadyExtracted)} documents already represented in contentParts: {documentsAlreadyExtracted}")
|
|
|
|
# Step 2: Extract from documentList only for documents NOT already in contentParts
|
|
extractedParts = []
|
|
if documentList and documentList.references:
|
|
self.services.chat.progressLogUpdate(operationId, 0.3, "Extracting content from documents")
|
|
chatDocuments = self.services.chat.getChatDocumentsFromDocumentList(documentList)
|
|
|
|
if chatDocuments:
|
|
# Filter: Only extract documents not already represented
|
|
documentsToExtract = [
|
|
doc for doc in chatDocuments
|
|
if doc.id not in documentsAlreadyExtracted
|
|
]
|
|
|
|
if documentsToExtract:
|
|
logger.info(f"Extracting content from {len(documentsToExtract)} new documents (skipping {len(chatDocuments) - len(documentsToExtract)} already represented)")
|
|
|
|
# Prepare extraction options
|
|
extractionOptions = parameters.get("extractionOptions")
|
|
if not extractionOptions:
|
|
extractionOptions = ExtractionOptions(
|
|
prompt="Extract all content from the document",
|
|
mergeStrategy=MergeStrategy(
|
|
mergeType="concatenate",
|
|
groupBy="typeGroup",
|
|
orderBy="id"
|
|
),
|
|
processDocumentsIndividually=True
|
|
)
|
|
|
|
# Extract content (without AI - pure extraction)
|
|
extractedResults = self.services.extraction.extractContent(documentsToExtract, extractionOptions)
|
|
|
|
# Combine all ContentParts from extracted results
|
|
for extracted in extractedResults:
|
|
if extracted.parts:
|
|
extractedParts.extend(extracted.parts)
|
|
|
|
logger.info(f"Extracted {len(extractedParts)} content parts from {len(extractedResults)} documents")
|
|
else:
|
|
logger.info(f"All documents from documentList are already represented in contentParts, skipping extraction")
|
|
|
|
# Step 3: Merge all contentParts
|
|
if contentParts:
|
|
# Preserve pre-extracted content metadata
|
|
for part in contentParts:
|
|
if part.metadata.get("skipExtraction", False):
|
|
part.metadata.setdefault("contentFormat", "extracted")
|
|
part.metadata.setdefault("isPreExtracted", True)
|
|
|
|
# Merge: extracted parts first, then provided contentParts
|
|
# This ensures extracted content comes before pre-extracted content
|
|
finalContentParts = extractedParts + contentParts
|
|
contentParts = finalContentParts
|
|
logger.info(f"Merged contentParts: {len(extractedParts)} extracted + {len(contentParts) - len(extractedParts)} provided = {len(contentParts)} total")
|
|
elif extractedParts:
|
|
contentParts = extractedParts
|
|
```
|
|
|
|
**Benefits:**
|
|
- Makes behavior consistent across all paths
|
|
- Allows users to combine pre-extracted content with documents
|
|
- Matches user expectations
|
|
- Follows the architectural pattern already established in document generation path
|
|
|
|
#### Edge Cases Handled
|
|
|
|
1. **Duplicate Documents**: Same document in both `contentParts` and `documentList`
|
|
- **Solution**: Check `documentId` in `contentParts` metadata before extracting
|
|
- **Implementation**: Build set of `documentsAlreadyExtracted` from `part.metadata.get("documentId")`
|
|
- **Result**: Only extract documents NOT already represented in `contentParts`
|
|
- **Benefit**: Avoids redundant extraction, prevents duplicate content
|
|
|
|
2. **Different Extraction Options**: contentParts might have different extraction settings
|
|
- **Solution**: Preserve metadata, let AI handle differences
|
|
- **Note**: Each ContentPart retains its own metadata (extractionPrompt, etc.)
|
|
- **Behavior**: Documents extracted with current options, pre-extracted parts keep their original metadata
|
|
|
|
3. **Ordering**: Which comes first - extracted or provided?
|
|
- **Solution**: Extracted parts first, then provided contentParts
|
|
- **Rationale**: Newly extracted content comes first, pre-extracted content follows
|
|
- **Implementation**: `finalContentParts = extractedParts + contentParts`
|
|
|
|
4. **Performance**: Avoids unnecessary extraction
|
|
- **Solution**: Only extracts documents not already in `contentParts`
|
|
- **Benefit**: Skips extraction for documents already represented
|
|
- **Logging**: Logs which documents are skipped and why
|
|
|
|
5. **Missing documentId in Metadata**: What if contentPart doesn't have documentId?
|
|
- **Solution**: Only documents with `documentId` in metadata are considered "already extracted"
|
|
- **Behavior**: If `documentId` missing, document will be extracted (safe default)
|
|
- **Note**: Extraction service always sets `documentId` in metadata, so this is rare
|
|
|
|
#### Implementation Steps
|
|
|
|
1. **Update `ai.process` action** (`process.py` lines 85-119):
|
|
- **Step 1**: Build set of `documentsAlreadyExtracted` from `contentParts` metadata
|
|
- **Step 2**: Filter `chatDocuments` to only include documents NOT in `documentsAlreadyExtracted`
|
|
- **Step 3**: Extract content only from filtered documents (pure extraction, no AI)
|
|
- **Step 4**: Merge extracted parts with provided `contentParts` (extracted first, then provided)
|
|
- **Step 5**: Preserve metadata for pre-extracted contentParts
|
|
- **Step 6**: Add logging for transparency (which documents skipped, counts, etc.)
|
|
|
|
2. **Update Documentation**:
|
|
- Update action parameter documentation to clarify deduplication behavior
|
|
- Document that extraction only happens for documents not already in `contentParts`
|
|
- Add examples showing both parameters used together
|
|
- Explain how `documentId` metadata is used for deduplication
|
|
|
|
3. **Testing**:
|
|
- **Test Case 1**: Both parameters provided, no overlap → Both extracted and merged
|
|
- **Test Case 2**: Both parameters provided, full overlap → Only contentParts used, no extraction
|
|
- **Test Case 3**: Both parameters provided, partial overlap → Extract only new documents, merge all
|
|
- **Test Case 4**: Only contentParts → Use as-is
|
|
- **Test Case 5**: Only documentList → Extract all documents
|
|
- **Test Case 6**: contentParts without documentId metadata → Extract all documents (safe default)
|
|
|
|
4. **Migration**:
|
|
- No breaking changes expected (only adds functionality)
|
|
- Existing code using only one parameter continues to work
|
|
- New behavior: When both provided, intelligently deduplicates before merging
|
|
|
|
### 9.2 Architectural Redundancy: Duplicate Extraction Logic
|
|
|
|
#### Problem Statement
|
|
|
|
**Current Architecture:**
|
|
- `ai.process` action extracts documents and creates `contentParts` (lines 86-119)
|
|
- Then passes only `contentParts` to `callAiContent()` (line 167)
|
|
- `callAiContent()` accepts both `contentParts` AND `documentList` (line 545)
|
|
- Document generation path has `extractAndPrepareContent()` logic (line 103 in `documentPath.py`)
|
|
- But this extraction logic is **never used** when called from `ai.process` (because `documentList` is not passed)
|
|
|
|
**Question**: Why does `ai.process` extract documents when the AI service already has extraction logic?
|
|
|
|
#### Analysis
|
|
|
|
**Current Flow:**
|
|
```
|
|
ai.process
|
|
├─→ Extract documents → contentParts (lines 86-119)
|
|
├─→ Pass contentParts to callAiContent() (line 167)
|
|
└─→ callAiContent() routes to document generation path
|
|
└─→ extractAndPrepareContent() exists but is SKIPPED (no documentList)
|
|
```
|
|
|
|
**Alternative Flow (More Logical):**
|
|
```
|
|
ai.process
|
|
├─→ Pass documentList to callAiContent() (line 167)
|
|
└─→ callAiContent() routes to document generation path
|
|
└─→ extractAndPrepareContent() handles extraction
|
|
```
|
|
|
|
#### Issues with Current Architecture
|
|
|
|
1. **Code Duplication**: Extraction logic exists in both `ai.process` and document generation path
|
|
2. **Inconsistency**: Different extraction paths use different extraction options/logic
|
|
3. **Maintenance Burden**: Changes to extraction logic must be made in multiple places
|
|
4. **Unused Code**: `extractAndPrepareContent()` in document generation path is unused when called from `ai.process`
|
|
5. **Loss of Flexibility**: `ai.process` can't leverage document intent clarification and other features in `extractAndPrepareContent()`
|
|
|
|
#### Why Current Architecture Exists (Possible Reasons)
|
|
|
|
1. **Historical**: Extraction may have been added to `ai.process` before AI service had extraction
|
|
2. **Separation of Concerns**: `ai.process` might be intended as a simpler entry point
|
|
3. **Progress Tracking**: Early extraction allows better progress tracking at action level
|
|
4. **Performance**: Early extraction might allow parallel processing
|
|
|
|
However, these don't justify the duplication and inconsistency.
|
|
|
|
#### Recommendation
|
|
|
|
**Option A: Remove Extraction from `ai.process` (Preferred)**
|
|
- `ai.process` should pass `documentList` to `callAiContent()` instead of extracting
|
|
- Let the AI service handle all extraction through `extractAndPrepareContent()`
|
|
- Benefits:
|
|
- Single source of truth for extraction logic
|
|
- Consistent extraction options and behavior
|
|
- Leverages document intent clarification
|
|
- Simpler `ai.process` action
|
|
- Better separation: action layer vs service layer
|
|
|
|
**Option B: Keep Extraction in `ai.process` but Make it Optional**
|
|
- Add parameter to control whether extraction happens in `ai.process` or AI service
|
|
- Still creates complexity and potential inconsistency
|
|
|
|
**Option C: Keep Current Architecture (Not Recommended)**
|
|
- Document the duplication and accept it
|
|
- Maintain extraction logic in both places
|
|
- Risk of divergence over time
|
|
|
|
#### Proposed Refactoring (Option A)
|
|
|
|
**Current Implementation** (`process.py` lines 85-119):
|
|
```python
|
|
# Extract in ai.process
|
|
if not contentParts and documentList.references:
|
|
extractedResults = self.services.extraction.extractContent(...)
|
|
contentParts = combineExtractedResults(extractedResults)
|
|
|
|
# Pass only contentParts
|
|
aiResponse = await self.services.ai.callAiContent(
|
|
contentParts=contentParts, # documentList NOT passed
|
|
...
|
|
)
|
|
```
|
|
|
|
**Proposed Implementation**:
|
|
```python
|
|
# Don't extract in ai.process - let AI service handle it
|
|
# Pass documentList to AI service
|
|
aiResponse = await self.services.ai.callAiContent(
|
|
prompt=aiPrompt,
|
|
options=options,
|
|
documentList=documentList, # Pass documentList instead
|
|
contentParts=contentParts, # Still support pre-extracted contentParts
|
|
outputFormat=output_format,
|
|
parentOperationId=operationId,
|
|
generationIntent=generationIntent
|
|
)
|
|
```
|
|
|
|
**Benefits:**
|
|
- Single extraction path in AI service
|
|
- Consistent extraction behavior
|
|
- Leverages document intent clarification
|
|
- Simpler `ai.process` action
|
|
- Better architecture: action layer delegates to service layer
|
|
|
|
**Migration Path:**
|
|
1. Update `ai.process` to pass `documentList` to `callAiContent()`
|
|
2. Remove extraction logic from `ai.process` (or make it optional)
|
|
3. Ensure `extractAndPrepareContent()` handles all extraction cases
|
|
4. Test that all existing workflows continue to work
|
|
5. Update documentation
|
|
|
|
**Edge Cases:**
|
|
- Pre-extracted `contentParts` should still be supported (merge with extracted)
|
|
- Extraction options should be configurable via parameters
|
|
- Progress tracking should work at both levels
|
|
|
|

The target state addresses all architectural issues identified:
|
|
1. **Single extraction path** in AI service (no duplication in `ai.process`)
|
|
2. **Intelligent merging** of `contentParts` and `documentList` with deduplication
|
|
3. **Clear separation** of concerns: action layer delegates to service layer
|
|
4. **Consistent behavior** across all code paths
|

#### Key Differences from Current State
|
|
|
|
**Current State Issues:**
|
|
1. ❌ `ai.process` extracts documents (duplication)
|
|
2. ❌ `ai.process` doesn't pass `documentList` to AI service
|
|
3. ❌ No deduplication when both `contentParts` and `documentList` provided
|
|
4. ❌ Inconsistent behavior across code paths
|
|
5. ❌ Pre-extracted JSON documents in `documentList` may not be properly identified
|
|
|
|
**Target State Benefits:**
|
|
1. ✅ Single extraction path in AI service
|
|
2. ✅ `ai.process` passes both `documentList` and `contentParts`
|
|
3. ✅ Intelligent deduplication (extract only new documents)
|
|
4. ✅ Pre-extracted JSON documents identified and processed as ContentParts (not regular JSON)
|
|
5. ✅ Original documents filtered out if covered by pre-extracted JSON
|
|
6. ✅ Consistent behavior across all code paths
|
|
7. ✅ Better separation of concerns
|
|
|
|
#### Document Intent Clarification Details
|
|
|
|
**What Happens in Phase 1:**
|
|
|
|
1. **Document Resolution**:
|
|
- Maps pre-extracted JSON documents to their original documents
|
|
- Creates `documentMapping` to track original → JSON document ID mapping
|
|
- Resolves documents for intent analysis (analyze original docs, not JSON)
|
|
|
|
2. **AI Analysis** (`clarifyDocumentIntents`):
|
|
- **Input**: User prompt, resolved documents, action parameters (outputFormat, etc.)
|
|
- **Process**: Uses AI (`callAiPlanning()`) to analyze how each document should be used
|
|
- **Output**: List of `DocumentIntent` objects, one per document
|
|
- **AI Call**: Structured JSON response with intents and reasoning
|
|
|
|
3. **Intent Determination**:
|
|
- **"extract"**: Content extraction needed (text, structure, OCR, etc.)
|
|
- Used for: PDFs, DOCX, images with text, tables, etc.
|
|
- Generates `extractionPrompt` for specific extraction needs
|
|
- Example: `"Extract all text content, preserving structure"`
|
|
- **"render"**: Image/binary should be rendered as-is (visual element)
|
|
- Used for: Images that should appear in final document
|
|
- No extraction prompt needed
|
|
- Example: Image that should be displayed in PDF/DOCX
|
|
- **"reference"**: Document reference/attachment (no extraction)
|
|
- Used for: Documents mentioned but not extracted
|
|
- No extraction prompt needed
|
|
- Example: Template document referenced but not included
|
|
|
|
4. **Multiple Intents**:
|
|
- A document can have multiple intents (e.g., `["extract", "render"]`)
|
|
- Example: Image that needs text extraction AND visual rendering
|
|
- Each intent creates a separate ContentPart later in extraction phase
|
|
|
|
5. **Extraction Prompt Generation**:
|
|
- AI generates specific extraction prompt for each document
|
|
- Based on user prompt, document type, and output format
|
|
- Examples:
|
|
- `"Extract all text content, preserving structure"`
|
|
- `"Extract text content from image using vision AI"`
|
|
- `"Extract tables and data, preserving formatting"`
|
|
- Stored in `DocumentIntent.extractionPrompt` for later use
|
|
|
|
6. **Mapping Back**:
|
|
- If intent was for original document, map back to JSON document ID
|
|
- Ensures intents are associated with correct documents
|
|
- Pre-extracted JSON documents get intents mapped correctly
|
|
|
|
**Example Flow**:
|
|
```
|
|
Input:
|
|
documents = [
|
|
ChatDocument(id="doc_1", fileName="report.pdf"),
|
|
ChatDocument(id="doc_2", fileName="image.jpg"),
|
|
ChatDocument(id="json_3", fileName="pre_extracted.json") # Pre-extracted
|
|
]
|
|
userPrompt = "Create a report with the PDF content and show the image"
|
|
|
|
Step 1: Map pre-extracted JSON
|
|
→ json_3 maps to original_doc_3
|
|
→ resolvedDocuments = [doc_1, doc_2, original_doc_3]
|
|
|
|
Step 2: AI Analysis
|
|
→ Analyzes: "Create report with PDF content and show image"
|
|
→ Determines:
|
|
- doc_1: ["extract"] (needs text extraction)
|
|
extractionPrompt: "Extract all text content, preserving structure"
|
|
- doc_2: ["render"] (needs visual rendering)
|
|
extractionPrompt: null
|
|
- original_doc_3: ["extract"] (needs extraction)
|
|
extractionPrompt: "Extract all text content, preserving structure"
|
|
|
|
Step 3: Map back
|
|
→ original_doc_3 intent mapped to json_3
|
|
→ Final intents:
|
|
- doc_1: ["extract"]
|
|
- doc_2: ["render"]
|
|
- json_3: ["extract"]
|
|
```
|
|
|
|
**Why This Matters**:
|
|
- Determines HOW each document should be processed (extract vs. render vs. reference)
|
|
- Generates appropriate extraction prompts for each document
|
|
- Handles pre-extracted JSON documents correctly (maps to original for analysis)
|
|
- Enables multiple intents per document (extract + render for images)
|
|
- Guides content extraction phase (Phase 2) on what to extract and how
|
|
|
|
**Output Structure**:
|
|
```python
|
|
DocumentIntent(
|
|
documentId: str, # Document ID
|
|
intents: List[str], # ["extract", "render", "reference"]
|
|
extractionPrompt: Optional[str], # Prompt for extraction (if extract intent)
|
|
reasoning: str # Why these intents were chosen
|
|
)
|
|
```
|
|
|
|
#### Pre-Extracted JSON Documents Handling
|
|
|
|
**Scenario**: ContentParts are already extracted and handed over as JSON documents in `documentList`
|
|
|
|
**Target State Behavior**:
|
|
|
|
1. **Identification** (Step 1 in Phase 2):
|
|
- Use `resolvePreExtractedDocument()` to identify JSON documents containing `ContentExtracted` structure
|
|
- These are NOT regular JSON documents - they contain pre-processed ContentParts
|
|
- Map back to original document ID to identify which original documents are covered
|
|
|
|
2. **Filtering** (Step 2 in Phase 2):
|
|
- Keep pre-extracted JSON documents (will be processed as ContentParts)
|
|
- Remove original documents if covered by pre-extracted JSON (prevents duplicate extraction)
|
|
- Keep regular documents (not pre-extracted, not covered)
|
|
|
|
3. **Processing** (Step 5 in Phase 2):
|
|
- Extract ContentParts from pre-extracted JSON (not treat as regular JSON)
|
|
- Process nested parts if structure parts contain nested ContentParts
|
|
- Apply intents (extract, render, reference) to each ContentPart
|
|
- Mark with metadata:
|
|
- `isPreExtracted: True`
|
|
- `fromPreExtractedJson: True`
|
|
- `originalFileName`: Original document filename
|
|
- `documentId`: Pre-extracted JSON document ID
|
|
|
|
4. **Merging** (Step 7 in Phase 2):
|
|
- Merge order: pre-extracted parts → extracted parts → provided contentParts
|
|
- All ContentParts treated equally regardless of source
|
|
|
|
**Example Flow**:
|
|
```
|
|
documentList = [
|
|
"doc:original_pdf_123", # Original PDF document
|
|
"doc:pre_extracted_json_456" # Pre-extracted JSON (contains ContentParts from original_pdf_123)
|
|
]
|
|
|
|
Step 1: Identify pre-extracted JSON
|
|
→ pre_extracted_json_456 is identified as pre-extracted
|
|
→ Maps to original_pdf_123
|
|
|
|
Step 2: Filter documents
|
|
→ Keep pre_extracted_json_456 (will extract ContentParts from JSON)
|
|
→ Remove original_pdf_123 (covered by pre-extracted JSON)
|
|
|
|
Step 5: Process pre-extracted JSON
|
|
→ Extract ContentParts from pre_extracted_json_456
|
|
→ Mark as isPreExtracted=True, fromPreExtractedJson=True
|
|
|
|
Step 6: Extract regular documents
|
|
→ No documents to extract (all filtered out or pre-extracted)
|
|
|
|
Step 7: Merge
|
|
→ finalContentParts = [ContentParts from pre_extracted_json_456]
|
|
```
|
|
|
|
**Key Point**: Pre-extracted JSON documents are identified BEFORE deduplication and processed as ContentParts, NOT as regular JSON documents. This prevents treating them as regular JSON and ensures ContentParts are properly extracted and used.
|
|
|
|
#### Migration Steps
|
|
|
|
**Phase 1: Update `ai.process` Action**
|
|
|
|
**Step 1.1: Remove Extraction Logic from `ai.process`**
|
|
- **File**: `gateway/modules/workflows/methods/methodAi/actions/process.py`
|
|
- **Lines**: 85-119
|
|
- **Action**: Remove or comment out extraction logic
|
|
- **Code Change**:
|
|
```python
|
|
# REMOVE THIS:
|
|
# if not contentParts and documentList.references:
|
|
# extractedResults = self.services.extraction.extractContent(...)
|
|
# contentParts = combineExtractedResults(extractedResults)
|
|
```
|
|
|
|
**Step 1.2: Pass `documentList` to `callAiContent()`**
|
|
- **File**: `gateway/modules/workflows/methods/methodAi/actions/process.py`
|
|
- **Line**: 167
|
|
- **Action**: Add `documentList` parameter
|
|
- **Code Change**:
|
|
```python
|
|
# CURRENT:
|
|
aiResponse = await self.services.ai.callAiContent(
|
|
prompt=aiPrompt,
|
|
options=options,
|
|
contentParts=contentParts, # Only contentParts
|
|
outputFormat=output_format,
|
|
parentOperationId=operationId,
|
|
generationIntent=generationIntent
|
|
)
|
|
|
|
# TARGET:
|
|
aiResponse = await self.services.ai.callAiContent(
|
|
prompt=aiPrompt,
|
|
options=options,
|
|
documentList=documentList, # ADD documentList
|
|
contentParts=contentParts, # Keep contentParts
|
|
outputFormat=output_format,
|
|
parentOperationId=operationId,
|
|
generationIntent=generationIntent
|
|
)
|
|
```
|
|
|
|
**Step 1.3: Update Progress Tracking**
|
|
- **File**: `gateway/modules/workflows/methods/methodAi/actions/process.py`
|
|
- **Action**: Remove extraction progress tracking (moved to AI service)
|
|
- **Note**: Progress tracking will happen in `extractAndPrepareContent()`
|
|
|
|
**Phase 2: Update Document Generation Path**
|
|
|
|
**Step 2.1: Document Intent Clarification (Already Exists)**
|
|
- **File**: `gateway/modules/services/serviceAi/subDocumentIntents.py`
|
|
- **Lines**: 30-120
|
|
- **Action**: Verify intent clarification works correctly with new flow
|
|
- **What it does**:
|
|
- **AI Analysis**: Uses AI to analyze user prompt and documents
|
|
- **Determines Intents**: For each document, determines how it should be used:
|
|
- `"extract"`: Content extraction needed (text, structure, OCR, etc.)
|
|
- `"render"`: Image/binary should be rendered as-is (visual element)
|
|
- `"reference"`: Document reference/attachment (no extraction, just reference)
|
|
- **Multiple Intents**: A document can have multiple intents (e.g., `["extract", "render"]` for images)
|
|
- **Extraction Prompt**: Generates specific extraction prompt for each document
|
|
- **Pre-Extracted JSON Handling**: Maps pre-extracted JSONs to original documents for analysis, then maps back
|
|
- **Example Output**:
|
|
```python
|
|
[
|
|
DocumentIntent(
|
|
documentId="doc_1",
|
|
intents=["extract"],
|
|
extractionPrompt="Extract all text content, preserving structure",
|
|
reasoning="User needs text content for document generation"
|
|
),
|
|
DocumentIntent(
|
|
documentId="doc_2",
|
|
intents=["extract", "render"], # Both!
|
|
extractionPrompt="Extract text content from image using vision AI",
|
|
reasoning="Image contains text that needs extraction, but also should be rendered visually"
|
|
)
|
|
]
|
|
```
|
|
- **Note**: This step already exists and works correctly, just needs to be verified with new flow
|
|
|
|
**Step 2.2: Identify Pre-Extracted JSON Documents**
|
|
- **File**: `gateway/modules/services/serviceGeneration/paths/documentPath.py`
|
|
- **Lines**: 62-87 (already exists, but needs to be integrated with deduplication)
|
|
- **Action**: Ensure pre-extracted JSON documents are identified BEFORE deduplication
|
|
- **Code Change**:
|
|
```python
|
|
# Step 1: Identify pre-extracted JSON documents
|
|
preExtractedDocs = []
|
|
originalDocIdsCoveredByPreExtracted = set()
|
|
for doc in documents:
|
|
preExtracted = self.services.ai.intentAnalyzer.resolvePreExtractedDocument(doc)
|
|
if preExtracted:
|
|
preExtractedDocs.append(doc)
|
|
originalDocId = preExtracted["originalDocument"]["id"]
|
|
originalDocIdsCoveredByPreExtracted.add(originalDocId)
|
|
logger.info(f"Found pre-extracted JSON {doc.id} covering original document {originalDocId}")
|
|
|
|
# Step 2: Filter out original documents covered by pre-extracted JSONs
|
|
filteredDocuments = []
|
|
for doc in documents:
|
|
preExtracted = self.services.ai.intentAnalyzer.resolvePreExtractedDocument(doc)
|
|
if preExtracted:
|
|
# Pre-extracted JSON - keep it (will be processed as ContentParts, not regular JSON)
|
|
filteredDocuments.append(doc)
|
|
elif doc.id in originalDocIdsCoveredByPreExtracted:
|
|
# Original document covered by pre-extracted JSON - skip it
|
|
logger.info(f"Skipping original document {doc.id} - already covered by pre-extracted JSON")
|
|
else:
|
|
# Regular document - keep it
|
|
filteredDocuments.append(doc)
|
|
|
|
documents = filteredDocuments
|
|
```
|
|
|
|
**Step 2.2: Add Deduplication Logic for Regular Documents**
|
|
- **File**: `gateway/modules/services/serviceGeneration/paths/documentPath.py`
|
|
- **Lines**: 101-119
|
|
- **Action**: Add deduplication before extraction (after pre-extracted JSON handling)
|
|
- **Code Change**:
|
|
```python
|
|
# Step 3: Identify already extracted documents (from contentParts)
|
|
documentsAlreadyExtracted = set()
|
|
if contentParts:
|
|
for part in contentParts:
|
|
documentId = part.metadata.get("documentId")
|
|
if documentId:
|
|
documentsAlreadyExtracted.add(documentId)
|
|
|
|
# Step 4: Filter documents to extract (exclude pre-extracted JSONs and already extracted)
|
|
documentsToExtract = [
|
|
doc for doc in documents
|
|
if doc.id not in documentsAlreadyExtracted
|
|
and not self.services.ai.intentAnalyzer.resolvePreExtractedDocument(doc) # Not pre-extracted JSON
|
|
]
|
|
|
|
# Step 5: Process pre-extracted JSON documents (handled in extractAndPrepareContent)
|
|
# Step 6: Extract regular documents
|
|
if documentsToExtract:
|
|
preparedContentParts = await extractAndPrepareContent(
|
|
documentsToExtract, # Only new documents (not pre-extracted, not already extracted)
|
|
documentIntents or [],
|
|
docOperationId
|
|
)
|
|
|
|
# Merge: pre-extracted parts + extracted parts + provided contentParts
|
|
if contentParts:
|
|
# Preserve metadata
|
|
for part in contentParts:
|
|
part.metadata.setdefault("isPreExtracted", True)
|
|
preparedContentParts.extend(contentParts)
|
|
|
|
contentParts = preparedContentParts
|
|
elif contentParts:
|
|
# All documents already extracted or pre-extracted, use contentParts as-is
|
|
contentParts = contentParts
|
|
```
|
|
|
|
**Step 2.4: Ensure Pre-Extracted JSON Processing**
|
|
- **File**: `gateway/modules/services/serviceAi/subContentExtraction.py`
|
|
- **Lines**: 75-253
|
|
- **Action**: Ensure `extractAndPrepareContent()` properly handles pre-extracted JSON documents
|
|
- **Note**: This logic already exists (lines 75-253) but needs to be verified:
|
|
- Pre-extracted JSON documents are identified via `resolvePreExtractedDocument()`
|
|
- ContentParts are extracted from JSON (not treated as regular JSON)
|
|
- Original documents are skipped if covered by pre-extracted JSON
|
|
- Metadata is preserved (`isPreExtracted`, `fromPreExtractedJson`)
|
|
|
|
**Step 2.5: Verify Pre-Extracted JSON Identification**
|
|
- **File**: `gateway/modules/services/serviceAi/subDocumentIntents.py`
|
|
- **Action**: Ensure `resolvePreExtractedDocument()` correctly identifies pre-extracted JSON documents
|
|
- **Requirements**:
|
|
- Must identify JSON documents containing `ContentExtracted` structure
|
|
- Must map back to original document ID
|
|
- Must extract ContentParts from JSON (not treat as regular JSON)
|
|
- Must preserve metadata (`isPreExtracted`, `fromPreExtractedJson`)
|
|
|
|
**Step 2.6: Update Extraction Logic**
|
|
- **File**: `gateway/modules/services/serviceAi/subContentExtraction.py`
|
|
- **Action**: Ensure extraction handles deduplication gracefully
|
|
- **Note**: Extraction service already supports this, just need to pass filtered documents
|
|
- **Important**: Pre-extracted JSON documents should be processed BEFORE regular extraction
|
|
|
|
**Phase 3: Testing and Validation**
|
|
|
|
**Step 3.1: Unit Tests**
|
|
- Test `ai.process` with only `documentList`
|
|
- Test `ai.process` with only `contentParts`
|
|
- Test `ai.process` with both `documentList` and `contentParts` (no overlap)
|
|
- Test `ai.process` with both `documentList` and `contentParts` (full overlap)
|
|
- Test `ai.process` with both `documentList` and `contentParts` (partial overlap)
|
|
|
|
**Step 3.2: Integration Tests**
|
|
- Test full document generation flow
|
|
- Test progress tracking at all levels
|
|
- Test error handling (missing documents, extraction failures)
|
|
- Test performance (no duplicate extraction)
|
|
|
|
**Step 3.3: Regression Tests**
|
|
- Ensure existing workflows continue to work
|
|
- Test backward compatibility
|
|
- Test edge cases (empty lists, missing metadata, etc.)
|
|
|
|
**Phase 4: Documentation Updates**
|
|
|
|
**Step 4.1: Update Action Documentation**
|
|
- **File**: `gateway/modules/workflows/methods/methodAi/methodAi.py`
|
|
- **Action**: Update parameter descriptions to clarify merging behavior
|
|
- **Content**: Document that both parameters can be provided and will be merged intelligently
|
|
|
|
**Step 4.2: Update API Documentation**
|
|
- Document new behavior in API docs
|
|
- Add examples showing both parameters used together
|
|
- Explain deduplication logic
|
|
|
|
**Step 4.3: Update This Analysis Document**
|
|
- Mark current state sections as "Current State (Pre-Migration)"
|
|
- Add "Target State" sections (this chapter)
|
|
- Document migration progress
|
|
|
|
**Phase 5: Rollout Strategy**
|
|
|
|
**Step 5.1: Feature Flag (Optional)**
|
|
- Add feature flag to control new vs. old behavior
|
|
- Allows gradual rollout
|
|
- Easy rollback if issues found
|
|
|
|
**Step 5.2: Gradual Migration**
|
|
- Migrate one workflow at a time
|
|
- Monitor for issues
|
|
- Collect feedback
|
|
|
|
**Step 5.3: Full Migration**
|
|
- Remove old extraction logic from `ai.process`
|
|
- Remove feature flag
|
|
- Update all documentation
|
|
|

### 9.4 Two-Phase Extraction: Why Extract Before Structure Generation?
|
|
|
|
#### Problem Statement
|
|
|
|
**Question**: Why do we extract content (Step 2) BEFORE structure generation (Step 3), when we need AI to fill sections (Step 4) anyway? Are we extracting twice?
|
|
|
|
**Answer**: Yes, but it's intentional and necessary. There are TWO different types of extraction happening at different phases:
|
|
|
|
1. **Phase 1 (Step 2)**: RAW extraction (parsing) - NO AI
|
|
2. **Phase 2 (Step 4)**: Vision AI extraction (for images only) - WITH AI
|
|
|
|
#### Analysis
|
|
|
|
**Phase 1: RAW Extraction (Step 2 - `extractAndPrepareContent`)**
|
|
|
|
**What happens:**
|
|
- Uses `extractContent()` service for pure document parsing
|
|
- Parses PDF, DOCX, XLSX, etc. to extract structured content
|
|
- Creates ContentParts with raw extracted data
|
|
- **No AI involved** - just parsing/parsing
|
|
|
|
**Prompt used:**
|
|
- `intent.extractionPrompt` or default `"Extract all content from the document"`
|
|
- **Important**: This prompt is stored in metadata but NOT used for AI extraction here
|
|
- It's only used later during section generation (Step 4) for Vision AI
|
|
|
|
**ContentPart preparation:**
|
|
- **For Images**:
|
|
- Marks with `needsVisionExtraction: True`
|
|
- Stores `extractionPrompt` in metadata
|
|
- **Reason**: Vision AI extraction is expensive, so it's deferred to section generation
|
|
- **For Text**:
|
|
- Marks with `skipExtraction: True` (already extracted, no AI needed)
|
|
- Text is already extracted from document parsing
|
|
- **For Objects**:
|
|
- Creates object ContentParts for rendering (images, videos, etc.)
|
|
|
|
**Why extract before structure generation?**
|
|
- ContentParts are needed BEFORE structure generation so AI can assign them to chapters
|
|
- Structure generation needs to know what content is available to assign to chapters
|
|
- The AI needs ContentPart metadata (documentId, typeGroup, etc.) to make intelligent assignments
|
|
|
|
**Phase 2: Vision AI Extraction (Step 4 - `fillStructure`)**
|
|
|
|
**What happens:**
|
|
- During section generation, checks for ContentParts with `needsVisionExtraction == True`
|
|
- Calls Vision AI with `extractionPrompt` from metadata (line 651 in `subStructureFilling.py`)
|
|
- Converts image ContentPart to text ContentPart with extracted text
|
|
- Then uses the text part for section generation
|
|
|
|
**Prompt used:**
|
|
- `part.metadata.get("extractionPrompt")` or default `"Extract all text content from this image. Return only the extracted text, no additional formatting."`
|
|
- This is the actual AI extraction prompt
|
|
|
|
**Why extract during section generation?**
|
|
- Vision AI extraction is expensive (costs tokens, takes time)
|
|
- Only needed when actually generating content for a section
|
|
- Not needed for structure generation (just needs to know images exist)
|
|
- Deferred extraction saves costs and improves performance
|
|
|
|
#### Current Flow
|
|
|
|
```
|
|
Step 2: extractAndPrepareContent()
|
|
├─→ RAW extraction (parsing PDF/DOCX/etc.) - NO AI
|
|
├─→ Creates ContentParts with raw data
|
|
├─→ For images: marks needsVisionExtraction=True, stores extractionPrompt
|
|
└─→ For text: marks skipExtraction=True (already extracted)
|
|
|
|
Step 3: generateStructure()
|
|
├─→ Uses ContentParts metadata to assign to chapters
|
|
└─→ Creates structure with contentPart assignments
|
|
|
|
Step 4: fillStructure()
|
|
├─→ For each section:
|
|
│ ├─→ Check if ContentPart needsVisionExtraction==True
|
|
│ ├─→ If yes: Call Vision AI with extractionPrompt (Phase 2 extraction)
|
|
│ ├─→ Convert image → text ContentPart
|
|
│ └─→ Generate section content with processed ContentParts
|
|
└─→ Text ContentParts: Used directly (skipExtraction=True)
|
|
```
|
|
|
|
#### Is This Optimal?
|
|
|
|
**Arguments FOR current approach:**
|
|
- Structure generation needs ContentParts early (to assign to chapters)
|
|
- Vision AI extraction is expensive - deferring saves costs
|
|
- Text content doesn't need AI extraction (already extracted in Phase 1)
|
|
- Clear separation: parsing vs. AI extraction
|
|
|
|
**Arguments AGAINST current approach:**
|
|
- Two-phase extraction can be confusing
|
|
- `extractionPrompt` stored but not used until later (unclear)
|
|
- Could potentially extract images earlier if structure generation needs text content
|
|
|
|
#### Recommendation
|
|
|
|
**Current approach is reasonable** but documentation should be clearer:
|
|
|
|
1. **Clarify terminology**:
|
|
- "Extraction" in Step 2 = RAW parsing (no AI)
|
|
- "Extraction" in Step 4 = Vision AI extraction (with AI)
|
|
|
|
2. **Document prompts clearly**:
|
|
- Step 2: `extractionPrompt` is stored but NOT used (just metadata)
|
|
- Step 4: `extractionPrompt` is actually used for Vision AI
|
|
|
|
3. **Consider renaming**:
|
|
- `extractAndPrepareContent()` → `parseAndPrepareContent()` (more accurate)
|
|
- `needsVisionExtraction` → `needsVisionAiExtraction` (clearer)
|
|
|
|
4. **Alternative approach** (if structure generation needs text from images):
|
|
- Extract images with Vision AI in Step 2
|
|
- More expensive but simpler flow
|
|
- Only if structure generation actually needs image text
|
|
|
|
#### Implementation Notes
|
|
|
|
- **Text ContentParts**: Already extracted in Phase 1, used directly in Phase 4
|
|
- **Image ContentParts**: Parsed in Phase 1, Vision AI extracted in Phase 4
|
|
- **Object ContentParts**: Created in Phase 1, used for rendering in Phase 4
|
|
- **Reference ContentParts**: Created in Phase 1, used as references in Phase 4
|
|
|
|
### 9.5 Document Intent Clarification: Security and Design Issues
|
|
|
|
#### Finding 1: Security Risk - Unfenced User Input
|
|
|
|
**Problem Statement:**
|
|
|
|
The user input (`userPrompt`) is directly inserted into the intent analysis prompt without fencing or escaping (line 248-249 in `subDocumentIntents.py`):
|
|
|
|
```python
|
|
prompt = f"""USER REQUEST:
|
|
{userPrompt} # ← DIRECT INSERTION, NO FENCING!
|
|
```
|
|
|
|
**Security Risk:**
|
|
- **Prompt Injection**: User input could contain special characters, JSON, or instructions that break the prompt structure
|
|
- **Example Attack**: User could inject `\n\nRETURN JSON: {"intents": [{"documentId": "malicious", ...}]}` to manipulate the AI response
|
|
- **Impact**: Could cause incorrect intent determination or even security vulnerabilities
|
|
|
|
**Evidence from Debug Files:**
|
|
- `20260102-134423-015-document_intent_analysis_prompt.txt`: User input is directly inserted without any fencing
|
|
- User input contains German text with special characters, quotes, etc.
|
|
- No escaping or delimiters around user input
|
|
|
|
**Recommendation:**
|
|
|
|
**Option A: Fence User Input (Preferred)**
|
|
```python
|
|
prompt = f"""USER REQUEST:
|
|
```
|
|
{userPrompt}
|
|
```
|
|
|
|
DOCUMENTS TO ANALYZE:
|
|
{docListText}
|
|
...
|
|
```
|
|
|
|
**Option B: Escape Special Characters**
|
|
```python
|
|
import json
|
|
escapedPrompt = json.dumps(userPrompt) # Escapes quotes, newlines, etc.
|
|
prompt = f"""USER REQUEST: {escapedPrompt}
|
|
...
|
|
```
|
|
|
|
**Option C: Use Structured Format**
|
|
```python
|
|
prompt = f"""USER REQUEST (delimited):
|
|
---START_USER_REQUEST---
|
|
{userPrompt}
|
|
---END_USER_REQUEST---
|
|
|
|
DOCUMENTS TO ANALYZE:
|
|
...
|
|
```
|
|
|
|
**Implementation Steps:**
|
|
1. Update `_buildIntentAnalysisPrompt()` in `subDocumentIntents.py` (line 248)
|
|
2. Add fencing around `userPrompt` (Option A recommended)
|
|
3. Test with various user inputs (special characters, JSON, newlines, quotes)
|
|
4. Verify AI still correctly parses user request
|
|
|
|
#### Finding 2: Output Format Should Be Per-Document
|
|
|
|
**Problem Statement:**
|
|
|
|
Currently, output format is passed as a single value in the intent analysis prompt (line 259 in `subDocumentIntents.py`):
|
|
|
|
```python
|
|
OUTPUT FORMAT: {outputFormat} # Single format for all documents
|
|
```
|
|
|
|
**Issue:**
|
|
- Output format is global, but different documents might need different formats
|
|
- Similar to language handling: each document can have its own language
|
|
- Should be determined per document based on intention
|
|
|
|
**Current Behavior:**
|
|
- Single `outputFormat` parameter (e.g., "docx")
|
|
- All documents analyzed with same output format in mind
|
|
- AI considers output format when determining intents (e.g., DOCX → images need "render")
|
|
|
|
**Proposed Behavior:**
|
|
- Each `DocumentIntent` should have optional `outputFormat` field
|
|
- AI determines output format per document based on user intention
|
|
- If not specified, use global output format as fallback
|
|
- Similar to language: per-document with fallback to global
|
|
|
|
**Example:**
|
|
```python
|
|
DocumentIntent(
|
|
documentId: str,
|
|
intents: List[str],
|
|
extractionPrompt: Optional[str],
|
|
reasoning: str,
|
|
outputFormat: Optional[str] = None # NEW: Per-document format
|
|
)
|
|
```
|
|
|
|
**Benefits:**
|
|
- More flexible: Different documents can have different output formats
|
|
- Better intention analysis: AI can determine format based on document purpose
|
|
- Consistent with language handling (per-document with fallback)
|
|
|
|
**Migration Steps:**
|
|
1. Add `outputFormat` field to `DocumentIntent` model (optional)
|
|
2. Update intent analysis prompt to ask AI to determine format per document
|
|
3. Update prompt to show: "OUTPUT FORMAT (default: {outputFormat})" instead of "OUTPUT FORMAT: {outputFormat}"
|
|
4. Update structure generation to use per-document format if available
|
|
5. Fallback to global format if not specified per document
|
|
|
|
**Updated Prompt Structure:**
|
|
```python
|
|
OUTPUT FORMAT (default: {outputFormat}):
|
|
- If not specified per document, use default format above
|
|
- Determine format per document based on user intention
|
|
- Examples: "docx", "pdf", "html", "json", etc.
|
|
|
|
RETURN JSON:
|
|
{{
|
|
"intents": [
|
|
{{
|
|
"documentId": "doc_1",
|
|
"intents": ["extract"],
|
|
"extractionPrompt": "...",
|
|
"outputFormat": "docx", # NEW: Per-document format
|
|
"reasoning": "..."
|
|
}}
|
|
]
|
|
}}
|
|
```
|
|
|
|
#### Implementation Priority
|
|
|
|
**High Priority:**
|
|
- Finding 1 (Security Risk): **CRITICAL** - Fix immediately
|
|
- Security vulnerability that could be exploited
|
|
- Easy to fix (add fencing)
|
|
- Low risk change
|
|
|
|
**Medium Priority:**
|
|
- Finding 2 (Output Format): **IMPROVEMENT** - Plan for next iteration
|
|
- Architectural improvement
|
|
- Requires model changes
|
|
- More complex migration

### 10.2 Detailed Implementation Steps
|
|
|
|
#### Step 1: Update DocumentIntent Model
|
|
|
|
**File**: `gateway/modules/datamodels/datamodelExtraction.py`
|
|
|
|
**Changes**:
|
|
```python
|
|
class DocumentIntent(BaseModel):
|
|
documentId: str
|
|
intents: List[str] # ["extract", "render", "reference"]
|
|
extractionPrompt: Optional[str] = None
|
|
outputFormat: Optional[str] = None # ← NEW: Per-document format
|
|
language: Optional[str] = None # ← NEW: Per-document language
|
|
reasoning: str
|
|
```
|
|
|
|
**Rationale**:
|
|
- Enables per-document output format and language determination
|
|
- Aligns with existing language handling pattern
|
|
- Allows AI to determine format/language based on document purpose
|
|
|
|
#### Step 2: Update Intent Analysis Prompt
|
|
|
|
**File**: `gateway/modules/services/serviceAi/subDocumentIntents.py`
|
|
|
|
**Changes**:
|
|
|
|
1. **Add fencing around userPrompt** (Security Fix):
|
|
```python
|
|
def _buildIntentAnalysisPrompt(
|
|
self,
|
|
userPrompt: str,
|
|
documents: List[ChatDocument],
|
|
actionParameters: Dict[str, Any]
|
|
) -> str:
|
|
# FENCE user input to prevent prompt injection
|
|
fencedUserPrompt = f"""```user_request
|
|
{userPrompt}
|
|
```"""
|
|
|
|
prompt = f"""USER REQUEST:
|
|
{fencedUserPrompt}
|
|
|
|
DOCUMENTS TO ANALYZE:
|
|
{docListText}
|
|
|
|
TASK: For each document, determine:
|
|
1. Intents (can be multiple): "extract", "render", "reference"
|
|
2. Output format (optional): If document should be rendered in specific format
|
|
3. Language (optional): If document content should be in specific language
|
|
|
|
OUTPUT FORMAT: {outputFormat} (global fallback)
|
|
|
|
RETURN JSON:
|
|
{{
|
|
"intents": [
|
|
{{
|
|
"documentId": "doc_1",
|
|
"intents": ["extract"],
|
|
"extractionPrompt": "Extract all text content",
|
|
"outputFormat": "pdf", // ← NEW: Optional, per-document
|
|
"language": "de", // ← NEW: Optional, per-document
|
|
"reasoning": "..."
|
|
}}
|
|
]
|
|
}}
|
|
"""
|
|
```
|
|
|
|
2. **Remove global outputFormat from prompt** (or keep as fallback only):
|
|
- Output format should be determined per document based on intent
|
|
- Global format remains as fallback if not specified per document
|
|
|
|
#### Step 3: Update ContentPart Metadata Propagation
|
|
|
|
**File**: `gateway/modules/services/serviceAi/subContentExtraction.py`
|
|
|
|
**Changes**:
|
|
```python
|
|
async def extractAndPrepareContent(
|
|
self,
|
|
documents: List[ChatDocument],
|
|
documentIntents: List[DocumentIntent],
|
|
parentOperationId: str,
|
|
getIntentForDocument: callable
|
|
) -> List[ContentPart]:
|
|
# ... existing extraction logic ...
|
|
|
|
# When creating ContentParts, propagate outputFormat and language from DocumentIntent
|
|
for part in allContentParts:
|
|
intent = getIntentForDocument(part.metadata.get("documentId"), documentIntents)
|
|
if intent:
|
|
# Propagate per-document format and language to ContentPart
|
|
if intent.outputFormat:
|
|
part.metadata["outputFormat"] = intent.outputFormat
|
|
if intent.language:
|
|
part.metadata["language"] = intent.language
|
|
```
|
|
|
|
**Rationale**:
|
|
- ContentParts carry format/language information through pipeline
|
|
- Enables per-document rendering in Phase 5
|
|
|
|
#### Step 4: Update Structure Generation
|
|
|
|
**File**: `gateway/modules/services/serviceAi/subStructureGeneration.py`
|
|
|
|
**Changes**:
|
|
|
|
1. **Determine per-document format/language from ContentParts**:
|
|
```python
|
|
def generateStructure(
|
|
self,
|
|
userPrompt: str,
|
|
contentParts: List[ContentPart],
|
|
outputFormat: str, # Global fallback
|
|
language: str, # Global fallback
|
|
parentOperationId: str
|
|
) -> Dict[str, Any]:
|
|
# Group ContentParts by documentId
|
|
partsByDocument = {}
|
|
for part in contentParts:
|
|
docId = part.metadata.get("documentId", "default")
|
|
if docId not in partsByDocument:
|
|
partsByDocument[docId] = []
|
|
partsByDocument[docId].append(part)
|
|
|
|
# Determine per-document format and language
|
|
documentFormats = {}
|
|
documentLanguages = {}
|
|
for docId, parts in partsByDocument.items():
|
|
# Get format from first ContentPart (all parts from same doc should have same format)
|
|
docFormat = parts[0].metadata.get("outputFormat") or outputFormat
|
|
docLanguage = parts[0].metadata.get("language") or language
|
|
documentFormats[docId] = docFormat
|
|
documentLanguages[docId] = docLanguage
|
|
|
|
# Update prompt to include per-document format/language
|
|
prompt = self._buildStructureGenerationPrompt(
|
|
userPrompt=userPrompt,
|
|
contentParts=contentParts,
|
|
documentFormats=documentFormats, # ← NEW
|
|
documentLanguages=documentLanguages, # ← NEW
|
|
globalOutputFormat=outputFormat, # Fallback
|
|
globalLanguage=language # Fallback
|
|
)
|
|
```
|
|
|
|
2. **Update prompt to include per-document format/language**:
|
|
```python
|
|
def _buildStructureGenerationPrompt(
|
|
self,
|
|
userPrompt: str,
|
|
contentParts: List[ContentPart],
|
|
documentFormats: Dict[str, str], # ← NEW
|
|
documentLanguages: Dict[str, str], # ← NEW
|
|
globalOutputFormat: str,
|
|
globalLanguage: str
|
|
) -> str:
|
|
# ... existing prompt building ...
|
|
|
|
# Add per-document format/language information
|
|
formatLanguageInfo = "\n## PER-DOCUMENT OUTPUT FORMATS AND LANGUAGES\n"
|
|
for docId, docFormat in documentFormats.items():
|
|
docLanguage = documentLanguages.get(docId, globalLanguage)
|
|
formatLanguageInfo += f"- Document {docId}: Format={docFormat}, Language={docLanguage}\n"
|
|
|
|
prompt += formatLanguageInfo
|
|
|
|
prompt += """
|
|
## DOCUMENT LANGUAGE
|
|
- Each document can have its own language (ISO 639-1 code: "de", "en", "fr", etc.)
|
|
- Per-document languages are listed above
|
|
- If not specified, use global language: "{globalLanguage}"
|
|
|
|
## OUTPUT FORMAT
|
|
- Each document can have its own output format
|
|
- Per-document formats are listed above
|
|
- If not specified, use global format: "{globalOutputFormat}"
|
|
"""
|
|
```
|
|
|
|
#### Step 5: Update Structure Filling - Two Prompt Types
|
|
|
|
**File**: `gateway/modules/services/serviceAi/subStructureFilling.py`
|
|
|
|
**Changes**:
|
|
|
|
1. **Ensure two prompt types are used** (already implemented, verify):
|
|
```python
|
|
async def _fillSingleSection(
|
|
self,
|
|
section: Dict[str, Any],
|
|
contentParts: List[ContentPart],
|
|
userPrompt: str,
|
|
generationHint: str,
|
|
# ... other params ...
|
|
) -> List[Dict[str, Any]]:
|
|
contentPartIds = section.get("contentPartIds", [])
|
|
hasContentParts = len(contentPartIds) > 0
|
|
|
|
if hasContentParts:
|
|
# PROMPT TYPE 1: WITH CONTENT (Aggregation)
|
|
# ContentParts passed as parameters, not in prompt text
|
|
isAggregation = True
|
|
relevantParts = [p for p in contentParts if p.id in contentPartIds]
|
|
|
|
generationPrompt = self._buildSectionGenerationPrompt(
|
|
section=section,
|
|
contentParts=relevantParts, # Passed as parameters
|
|
userPrompt=userPrompt,
|
|
generationHint=generationHint,
|
|
isAggregation=True, # ← Key flag
|
|
language=language
|
|
)
|
|
else:
|
|
# PROMPT TYPE 2: WITHOUT CONTENT (Generation)
|
|
# Only generationHint in prompt, no ContentParts
|
|
isAggregation = False
|
|
|
|
generationPrompt = self._buildSectionGenerationPrompt(
|
|
section=section,
|
|
contentParts=[], # Empty
|
|
userPrompt=userPrompt,
|
|
generationHint=generationHint,
|
|
isAggregation=False, # ← Key flag
|
|
language=language
|
|
)
|
|
```
|
|
|
|
2. **Verify `_buildSectionGenerationPrompt` handles both cases**:
|
|
```python
|
|
def _buildSectionGenerationPrompt(
|
|
self,
|
|
section: Dict[str, Any],
|
|
contentParts: List[ContentPart],
|
|
userPrompt: str,
|
|
generationHint: str,
|
|
isAggregation: bool, # ← Determines prompt type
|
|
language: str
|
|
) -> str:
|
|
if isAggregation:
|
|
# TYPE 1: WITH CONTENT
|
|
# ContentParts are passed as parameters to AI call
|
|
# Don't include full content in prompt text (token efficiency)
|
|
prompt = f"""Generate content for section based on provided ContentParts.
|
|
|
|
Section: {sectionTitle}
|
|
Generation Hint: {generationHint}
|
|
Language: {language}
|
|
|
|
ContentParts are provided as parameters (not shown in prompt for efficiency).
|
|
Use the ContentParts data to generate the section content.
|
|
"""
|
|
else:
|
|
# TYPE 2: WITHOUT CONTENT
|
|
# Only generationHint, no ContentParts
|
|
prompt = f"""Generate content for section based on generation hint.
|
|
|
|
Section: {sectionTitle}
|
|
Generation Hint: {generationHint}
|
|
Language: {language}
|
|
|
|
Generate content based on the generation hint without referencing external content.
|
|
"""
|
|
```
|
|
|
|
**Rationale**:
|
|
- **Type 1 (with content)**: Efficient for large content (ContentParts as parameters)
|
|
- **Type 2 (without content)**: Simple generation based on hint only
|
|
- Already implemented via `isAggregation` flag, verify it's used correctly
|
|
|
|
#### Step 6: Update Document Rendering
|
|
|
|
**File**: `gateway/modules/services/serviceGeneration/paths/documentPath.py`
|
|
|
|
**Changes**:
|
|
```python
|
|
async def renderDocuments(
|
|
self,
|
|
filledStructure: Dict[str, Any],
|
|
outputFormat: str, # Global fallback
|
|
language: str # Global fallback
|
|
) -> List[DocumentData]:
|
|
renderedDocuments = []
|
|
|
|
for doc in filledStructure.get("documents", []):
|
|
docId = doc.get("id")
|
|
docFormat = doc.get("outputFormat") or outputFormat # ← Use per-document format
|
|
docLanguage = doc.get("language") or language # ← Use per-document language
|
|
|
|
# Render document with per-document format and language
|
|
renderedDoc = await self._renderSingleDocument(
|
|
doc=doc,
|
|
outputFormat=docFormat,
|
|
language=docLanguage
|
|
)
|
|
renderedDocuments.append(renderedDoc)
|
|
|
|
return renderedDocuments
|
|
```
|
|
|
|
#### Step 7: Update ai.process to Pass documentList
|
|
|
|
**File**: `gateway/modules/workflows/methods/methodAi/actions/process.py`
|
|
|
|
**Changes**:
|
|
```python
|
|
# Phase 7.3: Pass both documentList and contentParts to AI service
|
|
# (Remove extraction logic from here - handled by AI service)
|
|
|
|
# Use unified callAiContent method with BOTH parameters
|
|
aiResponse = await self.services.ai.callAiContent(
|
|
prompt=aiPrompt,
|
|
options=options,
|
|
documentList=documentList, # ← PASS documentList (was missing)
|
|
contentParts=contentParts, # ← PASS contentParts
|
|
outputFormat=output_format,
|
|
parentOperationId=operationId,
|
|
generationIntent=generationIntent
|
|
)
|
|
```
|
|
|
|
**Rationale**:
|
|
- Centralizes extraction logic in AI service
|
|
- Enables intelligent merging with deduplication
|
|
- Consistent behavior across all code paths
|
|
|
|
### 10.3 Handover State Definitions

|
|
# All documents either extracted or pre-extracted

for p in contentParts)
|
|
```
|
|
|
|
#### State 5: After Document Rendering
|
|
```python
|
|
class DocumentRenderingState:
|
|
renderedDocuments: List[DocumentData] # Final output
|
|
|
|
# Validation

|
assert len(renderedDocuments) > 0
|
|
for doc in renderedDocuments:
|
|
assert doc.documentData # Non-empty
|
|
assert doc.mimeType # Valid MIME type
|
|
```
|
|
|
|
### 10.4 Migration Checklist
|
|
|
|
#### Phase 1: Model Updates
|
|
- [ ] Add `outputFormat` and `language` to `DocumentIntent` model
|
|
- [ ] Update intent analysis prompt parser to handle new fields
|
|
- [ ] Add validation for new fields
|
|
|
|
#### Phase 2: Intent Analysis Updates
|
|
- [ ] **CRITICAL**: Add fencing around `userPrompt` in intent analysis prompt
|
|
- [ ] Update prompt to ask for per-document format/language
|
|
- [ ] Update prompt to remove global outputFormat dependency (or keep as fallback)
|
|
- [ ] Test with various user inputs (special chars, JSON, newlines)
|
|
|
|
#### Phase 3: Content Extraction Updates
|
|
- [ ] Propagate `outputFormat` and `language` from `DocumentIntent` to `ContentPart.metadata`
|
|
- [ ] Verify pre-extracted JSON handling preserves format/language
|
|
- [ ] Test merging logic with format/language propagation
|
|
|
|
#### Phase 4: Structure Generation Updates
|
|
- [ ] Group ContentParts by documentId
|
|
- [ ] Determine per-document format/language from ContentPart metadata
|
|
- [ ] Update structure generation prompt to include per-document info
|
|
- [ ] Update structure output to include per-document format/language
|
|
|
|
#### Phase 5: Structure Filling Verification
|
|
- [ ] Verify two prompt types are correctly used:
|
|
- [ ] `isAggregation=True`: ContentParts as parameters
|
|
- [ ] `isAggregation=False`: Only generationHint
|
|
- [ ] Test both prompt types with various scenarios
|
|
- [ ] Verify Vision AI extraction happens during filling phase
|
|
|
|
#### Phase 6: Document Rendering Updates
|
|
- [ ] Use per-document format from structure
|
|
- [ ] Use per-document language from structure
|
|
- [ ] Fallback to global format/language if not specified
|
|
- [ ] Test multi-document rendering with different formats/languages
|
|
|
|
#### Phase 7: ai.process Refactoring
|
|
- [ ] Remove extraction logic from `ai.process`
|
|
- [ ] Pass `documentList` to `callAiContent()`
|
|
- [ ] Pass `contentParts` to `callAiContent()`
|
|
- [ ] Verify intelligent merging in AI service works correctly
|
|
|
|
#### Phase 8: Testing
|
|
- [ ] Test with pre-extracted JSON documents
|
|
- [ ] Test with mixed `documentList` + `contentParts`
|
|
- [ ] Test per-document format/language determination
|
|
- [ ] Test two prompt types in structure filling
|
|
- [ ] Test multi-document output with different formats/languages
|
|
- [ ] Test security: prompt injection attempts with fenced input
|
|
|
|
#### Phase 9: Documentation
|
|
- [ ] Update API documentation
|
|
- [ ] Update developer documentation
|
|
- [ ] Update user documentation (if applicable)
|
