What This Category of Data Looks Like
Data sources include social insurance management systems, tax social insurance premium collection systems, market entity registration information, and shared public security and civil affairs data. The update frequency is daily. Daily processed documents include social insurance registration forms, payment base declaration forms, personnel change forms, social insurance premium verification forms, and personal benefit records. The data includes both structured fields (such as unified social credit identifier, personnel ID number, payment verification amount) and unstructured explanatory content. Some documents mix natural line breaks and string escape line breaks. Fields cover core business information such as unit identifiers, personnel identities, and payment cycles.
Constraints on Knowledge Base Retrieval and Recall
Daily updated data requires the retrieval pipeline to support real-time synchronization, preventing expired social insurance registration or payment information from being recalled. Multi-source heterogeneous data sources require retrieval to associate identification fields from corresponding systems, avoiding cross-system data confusion. Mixed line breaks in documents require chunking logic to correctly identify actual line breaks, preventing truncation of complete business fields or generation of invalid empty chunks. Coexistence of structured fields and unstructured content requires retrieval modes to balance keyword matching and semantic understanding, accurately targeting core information such as personnel identities and payment bases.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Requires high-confidence matching of personnel identity and core payment information to filter low-relevance results |
limit | Top 6–10 results | Balances recall comprehensiveness for internal office work and context window usage |
searchMode | hybrid | Balances keyword matching for structured fields and semantic retrieval for unstructured content |
usingReRank | Enabled | In multi-source mixed data, uses re-ranking to improve the ranking priority of high-match results |
datasetSearchUsingExtensionQuery | Disabled | Social insurance payment data fields are clearly defined, so no additional expansion optimization for query content is needed |
collectionIds | Bind the corresponding human resources and social security insurance registration and payment knowledge base collection | Isolates data for different business scenarios to avoid retrieving irrelevant information from cross-scenario scenarios |
Three Common Configuration Mistakes
- The symptom is continuous empty lines in the knowledge base chunk preview, or complete payment base values being truncated into two chunks. The cause is failure to correctly handle mixed string escape "\n" and actual line breaks in documents, and failure to complete chunking based on actual line breaks.
- The symptom is retrieval results returning a large volume of cross-region social insurance data, without matching the target unit's business information. The cause is failure to set a reasonable
similaritythreshold, resulting in recall of low-relevance content with insufficient matching. - The symptom is empty results returned when a workflow calls knowledge base retrieval. The cause is failure to fill in the correct
collectionIdsin the configuration, with a knowledge base collection bound to a non-target business scenario.
How to Verify Successful Configuration
- Upload a social insurance registration form containing mixed line breaks, and check that the chunk preview splits content based on actual line breaks, with no extra empty lines or truncated fields.
- Send a query request containing a specific personnel ID number, and check that the
similarityscores of returned results fall within the preset range, and all results contain the target personnel's social insurance registration or payment information. - Configure the knowledge base retrieval node in a workflow, and check that the correct
collectionIdsare included in the call parameters, and no additional extended queries are triggered. - After enabling
usingReRank, compare result rankings before and after re-ranking, and confirm that high-match social insurance premium verification forms appear at the top of the results.
