What This Type of Data Looks Like
Business process data for state-owned industrial funds comes primarily from official documents including fund application guidelines, approval process rules, and material submission specifications. Updates align with policy adjustments or business process optimizations, with no fixed schedule. Most individual documents use structured content, with fields including business node names, processing time limits, submission material lists, and responsible departments. Processing time limits use working days as the unit. Material submission requirements use quantities and formats as specific units.
Constraints on Vector Models and Indexing Workflows
Structured business documents include multiple distinct fields. When creating vector chunks, retain field associations to avoid breaking business logic connections after splitting. Infrequent updates require indexes to support on-demand incremental synchronization. This avoids resource consumption from full index reconstruction. Multi-field business attributes require indexes to support filtering and retrieval by field dimension. This ensures returned results match business nodes or material requirements. Business content with units such as processing time limits requires the vector model to accurately capture the semantic binding between units and numerical values.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapts to the single-node content length of state-owned industrial fund business documents, avoiding splitting that damages field integrity |
| Overlap Length | 50–100 characters | Retains contextual connections between adjacent business nodes, preventing process logic breaks after chunking |
maxToken | 4096 token | Matches the input limit of the bge-m3 vector model, adapting to the content length after business document chunking |
| Similarity Threshold | 0.75–0.85, calibrated via actual testing | Filters low-match non-business-related results, ensuring retrieval results align with process nodes |
| Single Search Limit | Top 10 results | Controls the number of returned results, avoiding information overload for business process guidance |
defaultToken | 2048 token | Configures the default length of basic retrieval context, adapting to the semantic scope of common business questions |
Three Common Configuration Mistakes
- Phenomenon: After adding a new embedding model, retrieval tests return a 500 status code or "model loading failed" error. Cause: The business document format for state-owned industrial funds was not adapted to the new model’s input requirements, or the model configuration was not bound to the correct document data source path.
- Phenomenon: When checking the pg vector database, only vector data is stored. Retrieval cannot be performed by associating original document content. Cause: The associated ID field of the original document was not retained during chunking. Only text content was converted into a vector and stored in the database, losing the original data’s mapping relationship.
- Phenomenon: When using the bge-m3 vector model, semantic retrieval returns generally high similarity scores. Results are redundant, and matching degrees do not meet business expectations. Cause: Field filtering was not configured for the structured fields of state-owned industrial funds. Non-business-related similar content was misjudged as high-match results.
How to Verify Proper Configuration
- Run a retrieval test for a single business node. Confirm that the business fields of returned results match the original document content.
- Run an incremental update test. Confirm that only newly added or modified business documents are synchronized to the index database.
- Adjust the similarity threshold. Verify that the number and matching accuracy of returned results meet actual business guidance needs.
- View vector database storage records. Confirm that each vector entry is associated with the original document ID and corresponding field information.
