What Data for This Category Looks Like
Data for this category comes 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 on-site inspection records, interrogation transcripts, evidence lists, prior administrative penalty notification letters, hearing notification letters, penalty decisions, and service receipts. The core focus is on illegal facts and penalty decisions. Traceable penalty evidence chains and decision documents must be formed. Core business links include evidence collection, application of discretion benchmarks, legal review, and archiving.
Constraints Imposed on Vector Models and Indexing Workflows
Data sources are scattered and formats vary. Text extraction and vectorization workflows must support multiple document types. The daily update frequency requires lightweight index construction and update processes. This avoids blocking daily law enforcement operations. Individual documents have fixed structures but large differences in field information weights. Targeted chunking and indexing rules must be set. This ensures key evidence and legal clauses are not split. The seriousness of penalty case files requires high credibility for index recall results. Recall scope and matching accuracy must be strictly controlled. This prevents incorrect associations that lead to law enforcement risks.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapts to the paragraph length of administrative penalty documents, avoiding damage to the integrity of evidence chains or legal clauses |
| Overlap Length | 100–150 characters | Preserves cross-chunk key evidence associations, preventing chunk splitting from breaking the complete question-and-answer logic of interrogation transcripts |
| Similarity Threshold | 0.75–0.85, calibrated via actual testing | Balances recall accuracy and coverage, adapting to the matching accuracy of professional terms in law enforcement documents |
defaultToken | 4096 | Matches the total text length of most law enforcement documents, ensuring full loading of long documents such as penalty decisions |
| Single Search Limit | Top 5 entries | Controls the number of case files returned, avoiding context overload that reduces the accuracy of inquiry responses |
maxToken | 8192 | Adapts to the concatenated length of multiple associated documents, meeting full-case file query requirements during legal review |
Three Common Misconfigurations
- The index rebuild status displayed in the interface continues for more than 24 hours, and indexes cannot be switched normally. Cause: No incremental index strategy is set for daily updated law enforcement case file data. Full rebuild mode is used, which occupies a large amount of system resources and leads to an overly long rebuild cycle.
- Batch index addition request parameters are configured incorrectly. Some law enforcement transcript documents are not indexed properly. Cause: Chunking rules are not configured according to the field structure of law enforcement documents. Key information fields such as law enforcement personnel signatures and inspection times in on-site inspection records are omitted.
- Too many irrelevant case files are returned in search results. Target penalty decisions cannot be located accurately. Cause: The similarity threshold is set too low. A large number of unrelated law enforcement records are recalled. Matching accuracy is not adjusted in combination with professional terms in law enforcement scenarios.
How to Verify Successful Configuration
- Upload a standard administrative penalty decision document. Check if the chunked text retains complete illegal facts and penalty clauses, with no obvious content splitting.
- Trigger an incremental index task. Check if the task completion time meets expectations. Confirm that daily updated case file data can be synchronized to the index library normally.
- Enter an inquiry such as "the penalty basis for a certain case". Check if the number of returned recall results matches the single search limit setting, and all results are relevant case file documents.
- Confirm that the currently used FastGPT version is v4.17.0. This ensures configuration compatibility and normal function operation.
