What the data for this category looks like
The core data for this category comes from work safety supervision systems, enterprise hazard self-inspection systems, law enforcement inspection records, and accident statistics systems, with a daily update frequency. Commonly processed documents include hazard investigation checklists, hazard management ledgers, rectification notices, re-inspection records, and major hazard suspension and supervision orders. Document structures include structured fields such as hazard level and rectification deadline, as well as unstructured descriptive content. Key fields include hazard location, responsible party, rectification requirements, and other critical information. There is no fixed unified format, with slight variations across business scenarios.
What constraints do these characteristics impose on the knowledge base retrieval and recall link
Daily updated data requires the retrieval link to support incremental synchronization and rapid refresh to avoid review delays. Unstructured document structures and diverse field combinations require retrieval models to adapt to text matching across different formats, and cannot rely on single structured field retrieval. The rigor of hazard review requires that recalled results must accurately match hazard judgment standards and rectification requirements, otherwise serious consequences may occur. Additionally, case file review requires associating multiple documents such as investigation checklists and rectification notices, which requires the retrieval link to support cross-document associated recall.
How to configure settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Adapts to semantic matching precision for hazard descriptions, filters low-relevance non-business documents, and ensures recalled content is strongly relevant to hazard review |
limit | Top 10 entries | Controls the number of single-recall results, adapts to the batch reading rhythm of case file review, and avoids information overload |
searchMode | vector | Prioritizes matching semantic content related to hazards, adapts to the unstructured characteristics of documents in this category, and improves retrieval coverage |
usingReRank | Enabled | Improves the sorting priority of highly relevant results, ensures documents related to major hazards are retrieved first, and meets the rigorous requirements of review |
datasetSearchUsingExtensionQuery | Enabled | Expands the retrieval scope, covers associated content between hazard investigation checklists and rectification notices, and meets the cross-document association requirements of case file review |
collectionIds | Specified by business dataset | Limits the retrieval scope, only includes document sets related to hazard investigation and management, and avoids mixing irrelevant business data |
Three common mistakes
- Only a small number of documents are returned when exporting knowledge base file details. The cause is that
collectionIdsis not configured to limit the dataset scope, only the default general document set is retrieved, and the exclusive dataset for work safety hazard investigation and management is not included. - An empty result is returned after calling the create training order interface. The cause is that the associated parameters of
datasetSearchUsingExtensionQueryare not correctly set, causing the training task to fail to trigger, and the vectorization processing of documents cannot be completed. - Uploaded chaptered hazard documents cannot be associated after being split. The cause is that parameters are not configured according to grouping rules, causing hazard investigation checklists, rectification notices, and re-inspection records in the same group to be split into independent chunks, making associated retrieval impossible.
How to confirm the configuration is correct
- Perform the knowledge base file details export operation, confirm that the returned document list includes exclusive documents for this category such as hazard investigation checklists, rectification notices, and re-inspection records.
- Call the create training order interface, verify that the returned task status is pending processing or started, and there are no abnormal error messages.
- Upload grouped documents including chapter titles, links, and summaries, confirm that the returned retrieval results include complete intra-group information, and no splitting occurs.
- Adjust the
similarityparameter value, verify that the relevance of retrieval results changes as expected with the parameter, and ensure that recalled content matches hazard review requirements.
