What Data for This Category Looks Like
Data sources for this category include regulatory standards, online environmental monitoring equipment, gas detectors, personnel qualification files, equipment isolation lists, and supervision platforms. Daily documents cover risk identification lists, work tickets for hot work, confined space work, hoisting and other operations, environmental monitoring records, hazardous waste ledgers, emission data reports, and accident and hidden danger rectification reports. Data is updated after each operation is completed, in real time, as required by monitoring cycles, or during regular compliance inspections. Documents include dedicated fields such as work permit numbers, monitoring times, and hazardous waste categories.
How These Characteristics Impose Constraints on the "Knowledge Base Retrieval and Recall" Link
This category has diverse data sources, including both structured monitoring data and unstructured work ticket text. This requires retrieval to adapt to text blocks of different formats. Frequent updates require the knowledge base synchronization cycle to match business rhythms and avoid content lag. The strong compliance requirements of work permits and risk identification necessitate precise recall of content matching the current operation type and scenario. The serious consequences of errors require ensuring the accuracy and relevance of retrieved content, to avoid drafting content that does not meet compliance requirements.
Configuration Settings
This configuration is based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | This category involves highly compliant operational content, requiring a high matching threshold to filter irrelevant references |
limit | Top 8 entries | Reference content for operation drafting needs to be precise; too many entries will cause redundant context |
usingReRank | Enabled | This category has large differences in document structure, and re-ranking can improve the ranking priority of highly relevant content |
datasetSearchUsingExtensionQuery | Disabled | This category’s data is exclusive compliance content, and expanded search may easily introduce irrelevant documents |
collectionIds | Bind exclusive safety and environmental protection operation document collections | Ensure the retrieval scope only covers exclusive data for this category |
Three Common Misconfigurations
- Symptom: An error occurs during question answering after adding a knowledge base, but knowledge base search works normally when tested individually. Cause: The exclusive safety and environmental protection operation document collection is not correctly bound, and the retrieval scope mixes knowledge base content from other categories, leading to format or compliance conflicts during generation.
- Symptom: After switching the knowledge base vector model, the synchronization progress stalls for more than 300 seconds and cannot be rolled back. Cause: The associated model of the current collection is not locked in the configuration, and the cache index of the old model is not cleaned during switching, resulting in abnormal system resource occupation.
- Symptom: When using the knowledge base to draft an exception report, the returned reference content does not match the current operation scenario. Cause: The similarity threshold is set too low, resulting in recall of a large number of low-relevant historical records or general regulations, without precise matching of the current operation type and risk points.
How to Verify Successful Configuration
- Enter the knowledge base retrieval test page, enter a risk identification question for a certain type of operation, and check whether the recalled content includes the work ticket template and regulatory requirements corresponding to that operation.
- Try switching the knowledge base vector model, confirm that the switch can be completed normally, and the retrieval results of the new model meet expectations.
- Export the current knowledge base configuration information, check whether the collection ID only binds exclusive documents for safety, environmental protection and special operations management.
- Simulate drafting an exception report, and check whether the generated reference content covers necessary fields such as emission monitoring, personnel qualifications, and isolation lists.
