What data looks like for this category
Typical data for this category comes from social insurance management systems, personal benefit records, labor relations and work injury identification systems, and electronic social security card platforms. Data updates happen daily. Common business documents include benefit application forms, payment duration certificates, retirement approval forms, work injury identification materials, and unemployment insurance benefit application materials. Document structures include qualification condition fields, payment duration fields, benefit standard fields, and similar categories. Some materials combine structured tables and unstructured text content.
Constraints for vector models and indexing workflows
Daily updated data sources require indexes to support incremental construction, to avoid resource consumption from full rebuilds. Mixed document types, including structured tables and unstructured text, require chunking strategies that balance text integrity and field relevance. This prevents splitting key calculation information such as payment duration and benefit standards. Business data directly links to benefit payment results, so vector recall accuracy must match the strict standards of qualification review. This avoids irrelevant materials interfering with search results. Field format differences across source systems require basic field standardization before index construction, to ensure consistency in vector encoding.
Configuration settings
| Configuration Item | Recommended Setting | Rationale | |
|---|---|---|---|
| Chunk Length | 800–1200 characters | Adapts to the typical text length of benefit application forms and work injury identification materials, avoids splitting cross-chunk key qualification conditions | |
| Overlap Length | 100–200 characters | Preserves core information spanning chunks, such as payment duration and benefit standards, prevents key data from breaking after chunking | |
| Similarity Threshold | 0.75–0.85 | Matches the high-precision recall requirements of benefit verification business, filters low-relevance non-business materials | |
| Single Search Limit | Top 10 results | Covers the combined retrieval needs of multiple related materials, such as combined retrieval of work injury identification and payment duration certificates | |
defaultToken | 4096 | Adapts to long-context question answering related to benefit calculation, ensures complete loading of policy basis and business material information | |
maxToken | 8192 | Calibrated based on actual testing | Addresses multi-material splicing scenarios for batch benefit verification, meets context requirements for long-text retrieval |
Three common configuration errors
- Observation: After calling the knowledge base API to create a training order, business data fails to complete index construction. Cause: Target documents such as benefit application forms and work injury identification materials are not bound to the collection corresponding to the training order, or the automatic index trigger switch is not enabled.
- Observation: Search results do not return matching content for image-format business materials. Cause: The image vectorization configuration item is not enabled, or uploaded images are not associated with the target collection in business document format.
- Observation: The system prompts that the specified Embedding model cannot be selected. Cause: The API key for the corresponding model is not configured in FastGPT v4.17.0, or connectivity verification for the model interface is not completed in the local deployment environment.
How to verify correct configuration
- Upload a single work injury identification material. Run a retrieval test related to qualification conditions. Confirm whether corresponding matching content is included in recall results.
- View the collection’s index logs. Confirm that daily updated social security data has completed incremental index construction.
- Test combined retrieval of multiple materials. Confirm that relevant content from payment duration certificates and unemployment insurance benefit application materials can be recalled simultaneously.
- Check the model configuration page. Confirm that the target Embedding model is included in the available list and has its API key bound.
