What This Category of Data Looks Like
Law enforcement agencies across market supervision, ecological environment, and transportation sectors provide data for this category via their administrative law enforcement systems, law enforcement recorder footage, the national enterprise credit information publicity system, and departmental supervision databases. The data updates daily. Daily documents include on-site inspection records, interrogation statements, evidence lists, prior penalty notification documents, penalty decisions, and delivery receipts. Data fields include law enforcement subject, illegal facts, penalty basis, document number, delivery date, and other relevant details. The structure of this data is fixed, and a complete penalty evidence chain must be formed.
What Constraints Do These Characteristics Impose on the Vector Models and Indexing Link
Mixed indexing requirements arise from the multiple data types supported. The system must extract vectors for both text case files and law enforcement footage. Daily incremental updates require the indexing system to support efficient incremental synchronization and deduplication, to avoid duplicate storage of identical case file content. Fixed-structure law enforcement documents require chunking logic that aligns with document chapters, to prevent splitting of content related to the evidence chain. The strict rigor of penalty case files requires strict control over indexing matching accuracy, to prevent incorrect association of unrelated case files that could lead to law enforcement errors.
How to Configure the Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Aligns with the semantic completeness of single-paragraph content in administrative penalty documents, to avoid truncation of critical evidence |
| Overlap Length | 100–150 characters | Connects law enforcement logic between adjacent chunks, to prevent key evidence chain information from being split across two chunks |
defaultToken | 4096 token | Covers the full context of a single core case file, to meet information extraction needs for ledger summary |
maxToken | 8192 token | Limits the total content length loaded in a single operation, to avoid timeout errors during batch indexing |
| Similarity Threshold | 0.75–0.85 | Differentiates similar illegal facts and duplicate case files, to reduce the probability of mismatches |
| Single Search Limit | Top 8 entries | Matches the typical number of associated law enforcement case files, covers core evidence and document content |
Three Common Misconfigurations
- Phenomenon: When uploading a single administrative penalty case file, it displays 8 chunks, but subsequent index records show 13 chunks with duplicate fragments. Cause: Index deduplication verification is not enabled, and the system did not associate segmented records from the existing index when automatically re-chunking.
- Phenomenon: After upgrading FastGPT v4.17.0, previously retrievable case file content cannot be queried normally. Cause: The indexing format was updated during version iteration, and a full re-indexing operation was not performed.
- Phenomenon: Vector model training only supports adjusting parameters for a single file before uploading, and batch training tasks cannot be executed. Cause: Batch indexing trigger rules are not configured, and the system submits training tasks on a per-file basis by default.
How to Confirm Proper Configuration
- Upload a standard administrative penalty decision document, check that the number of chunk previews matches expectations, and there are no duplicate segment records.
- Initiate a retrieval request for a specific illegal fact, verify that the returned results include associated documents such as corresponding interrogation statements and evidence lists.
- Adjust the
defaultTokenparameter and submit a batch indexing task, confirm that the task log shows the parameter has taken effect as set. - View the statistical data of daily incremental indexing, confirm that the updated quantity matches the actual number of administrative penalty case files generated that day.
