What the data for this use case looks like
This use case serves law enforcement agencies such as market supervision and ecological environment departments. Daily processed documents include on-site inspection records, interrogation records, evidence lists, prior administrative penalty notification letters, hearing notification letters, penalty decisions, and service receipts. Data comes from administrative law enforcement case handling systems, law enforcement recorder footage, the national enterprise credit information publicity system, and departmental supervision databases, with a daily update frequency. Most documents use law enforcement-specific formats, and include dedicated fields such as law enforcement personnel information, party information, illegal facts, legal provisions, and discretion benchmarks.
Constraints imposed by these characteristics on knowledge base retrieval and recall
The specialized terminology and fixed formats of law enforcement-specific documents require retrieval to precisely match professional expressions, avoiding ambiguity from general-purpose retrieval. Daily data updates require the knowledge base synchronization frequency to align with the business data update rhythm, ensuring that the latest regulatory information and case handling records are recalled. Unlike administrative inspections, a traceable penalty evidence chain must be formed. This requires retrieval results to cover all document types required for the evidence chain, and align with legal review standards. Mixed calls from multiple data sources require strict restriction of the retrieval scope to prevent irrelevant business content from affecting review efficiency.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Administrative penalty case files involve law enforcement terminology and legal documents, so low-match irrelevant content must be filtered to ensure retrieval accuracy |
limit | Top 10 results | Case file review requires associating multiple types of documents such as records, legal provisions, and discretion benchmarks. Controlling the number of returned results avoids context overflow |
searchMode | Professional document matching | Optimize recall logic for the terminology system of law enforcement-specific documents, avoiding ambiguity from general-purpose retrieval |
usingReRank | Enabled | Perform secondary sorting on initial recall results by semantic relevance, improving the ranking priority of core legal provisions and compliant documents |
datasetSearchUsingExtensionQuery | Enabled | Automatically supplement synonyms and standard expressions related to the law enforcement field, covering professional terms such as "discretion benchmarks" and "illegal facts" |
collectionIds | Bind to law enforcement case handling exclusive knowledge base | Only retrieve exclusive documents such as uploaded law enforcement records and penalty decisions, avoiding mixing in irrelevant business data |
Three Common Configuration Errors
- Phenomenon: Empty results are returned after calling the retrieval interface, or specified law enforcement documents cannot be recalled. Cause: The
collectionIdsparameter is not configured correctly, and the corresponding law enforcement case handling exclusive knowledge base is not bound. - Phenomenon: The retrieval results contain a large number of non-law enforcement general documents, and low-match content is recalled first. Cause: A reasonable
similaritythreshold is not set, or the professional document matching mode ofsearchModeis not enabled. - Phenomenon: The number of retrieval results is insufficient to cover all document types required for case file review. Cause: The
limitparameter is set too low, ordatasetSearchUsingExtensionQueryis not enabled to cover synonyms of professional terms.
How to Verify Correct Configuration
- Enter the FastGPT knowledge base management page, confirm that law enforcement-specific documents such as on-site inspection records and penalty decisions have been uploaded, and record the corresponding collection IDs.
- Call the retrieval interface, pass the configured
similarity,limitand other parameters, enter professional terms such as "administrative penalty discretion benchmarks", and check the document types and match degree of the returned results. - Simulate a case file review scenario, enter a query term for a type of illegal fact, and confirm that the recall results include the corresponding evidence list, interrogation record template, and legal provisions.
- View the retrieval log to confirm that each retrieval only calls the bound law enforcement case handling exclusive knowledge base, and no irrelevant business data is returned.
