What this category of data entails
Core data sources include social insurance handling systems, tax social insurance premium collection systems, market entity registration information, and shared public security and civil affairs data. The update frequency is daily. Commonly processed documents include insurance participation registration forms, premium base declaration forms, personnel change forms, social insurance premium verification notices, and personal social security benefit records. Most documents include structured fields such as personnel identity information, insurance participation status, premium payment base, and unit registration information, as well as unstructured content such as declaration instructions and verification requirements. Data flows cover the pre-insurance-participation and premium-payment stages. These data are primarily used for personnel identity and labor relationship verification, personnel changes and base declaration, and tax collection data reconciliation.
Constraints imposed on knowledge base retrieval and recall
Multiple data sources require retrieval to integrate structured and unstructured content across systems, to avoid information gaps from single data sources. The daily update frequency requires retrieval configurations to adapt to incremental synchronization mechanisms, to ensure that knowledge base content matches business data in real time. The fixed field structure of documents requires retrieval to accurately match core fields such as personnel identity and premium payment base, to reduce interference from irrelevant results. The time-consuming verification process requires retrieved results to have high precision, to reduce the workload of manual review. The serious consequences of errors require retrieved results to have high confidence, to avoid incorrect information affecting insurance participation, premium payment, and benefit records.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75-0.85 | Balances retrieval precision and recall range, adapts to the strict requirements of social security data for information accuracy |
limit | Top 10 entries | Covers multiple associated documents required for declaration materials and file review, while avoiding excessive content that causes context overload |
searchMode | Hybrid semantic retrieval + keyword retrieval mode | Balances exact matching of structured fields and semantic understanding of unstructured content, adapting to the mixed format characteristics of documents in this category |
usingReRank | Enabled | Performs secondary ranking on initially retrieved results, to improve the display priority of core business documents |
datasetSearchUsingExtensionQuery | Enabled | Covers multiple expression variants of declaration materials, such as equivalent terms for "personnel change form" and "insurance participation personnel adjustment form" |
collectionIds | Bind the exclusive knowledge base collection for this category | Limits the retrieval scope, eliminating interference from irrelevant data of other business categories |
Three common misconfigurations
- Symptom: After upgrading FastGPT v4.17.0, the knowledge base page displays a "dataset not bound" error or is blank, and clicking the knowledge base module triggers a parameter error prompt. Cause: The exclusive dataset bound to
collectionIdswas not reconfirmed during the upgrade, resulting in lost configuration or invalid binding relationships. - Symptom: No results are returned more than 15 seconds after initiating retrieval, and timeout logs appear in the console. Cause: The
limitparameter was not set appropriately, and too many documents were retrieved, causing the context length to exceed the processing limit and triggering a timeout. - Symptom: Benefit verification-related documents are mixed in the retrieval results, interfering with personnel identity verification. Cause:
collectionIdswas not configured correctly, and cross-category knowledge base collections were bound, resulting in a retrieval scope that exceeds business boundaries.
How to confirm correct configuration
- Access the FastGPT knowledge base management backend, check whether
collectionIdsis only bound to the exclusive dataset collection for this category. - Initiate a business-related test query, such as "Key points for review of unit insurance participation personnel change declaration", and verify whether the
similarityscore of the returned results falls within the 0.75-0.85 range. - After enabling
usingReRank, view the sorted results, and confirm that core business documents such as insurance participation registration forms and premium base declaration forms are ranked first. - Check the system console logs to confirm that no parameter exceptions or timeout errors occur in retrieval requests.
