What this category of data looks like
This category of data originates from administrative law enforcement case handling systems, law enforcement recorder footage, the National Enterprise Credit Information Publicity System, and departmental supervision databases. The update frequency is daily. Daily documents include full-process case handling files such as on-site inspection records, interrogation records, evidence lists, prior penalty notification letters, hearing notification letters, penalty decisions, and delivery receipts. Data fields cover law enforcement subject information, descriptions of illegal facts, reference of discretion benchmarks, penalty decision content, delivery records, and more. All data forms a traceable evidence chain centered on illegal facts and penalty decisions, with no additional custom unit fields.
Constraints these characteristics impose on the knowledge base retrieval and recall link
The scattered nature of data sources requires the retrieval link to support associated recall across multiple data source knowledge bases. The daily update rhythm requires the knowledge base synchronization mechanism to align with the real-time data update needs of law enforcement case handling. The structural differences across multiple types of case handling documents require retrieval configurations to adjust recall rules based on the field characteristics of different documents. The business logic centered on illegal facts and penalty decisions requires retrieval results to accurately match legal clauses, discretion benchmarks, and other policy basis, to avoid reference errors. Additionally, the traceability requirement for case handling requires recalled documents to be linkable to specific law enforcement stages, to facilitate subsequent legal review.
How to configure the settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Meets the accuracy requirement for matching policy basis and case handling documents, and avoids mixing in low-correlation results |
limit | Top 8 entries | Covers all document types required for administrative penalty case handling, while controlling context length |
searchMode | Hybrid semantic and keyword retrieval mode | Balances keyword matching for policy clauses and semantic association for case handling documents |
usingReRank | Enabled | Improves the sorting priority of highly relevant results, to meet precise retrieval needs |
datasetSearchUsingExtensionQuery | Enabled | Optimizes extended queries for policy basis-related questions, to match standard expressions of legal clauses |
collectionIds | Bind to exclusive knowledge base collections for administrative law enforcement case handling | Limits retrieval scope to prevent interference from irrelevant data |
Three common configuration mistakes
- Symptom: Knowledge base retrieval is triggered unstably during conversations, and some sessions return preset content directly without executing retrieval. Cause: The knowledge base retrieval node is not forcibly bound in the workflow, or trigger rules for forced retrieval are not configured.
- Symptom: Knowledge base search returns empty results, and the workflow node does not trigger subsequent logic. Cause: No fallback branch is configured for empty search results, and the
similaritythreshold is set too high, filtering out valid results. - Symptom: An error occurs when passing custom variables during knowledge base retrieval, and returned fields are empty. Cause: The scope of the knowledge base ID variable is not correctly bound, or the variable format does not meet system requirements.
How to verify a successful configuration
- Input a policy basis question related to a specific type of administrative penalty, check the relevance of returned results, and adjust the
similaritythreshold to meet business requirements. - After enabling
usingReRank, confirm that highly matched policy and legal documents are ranked at the top of results. - Verify that the retrieval scope only covers the exclusive knowledge base for administrative law enforcement case handling, to exclude irrelevant data interference.
- After configuring
datasetSearchUsingExtensionQuery, input a simplified policy question, and confirm that accurate basis documents can be retrieved.
