What Data Looks Like for This Category
This category covers data from EHS departments and maintenance teams of manufacturing enterprises in chemical, metallurgical, machinery, light industry and other sectors. Data sources include regulatory standards, online environmental monitoring equipment, gas detectors, personnel qualification files, equipment isolation lists, and supervision platforms. Daily generated documents include risk identification records, work permits for hot work, confined space work, lifting operations and other types, environmental monitoring records, hazardous waste ledgers, emission monitoring data, and accident and hidden danger rectification reports. Data updates occur with single job completion, real-time monitoring, or regular inspections. Documents contain fields such as operation type, qualification number, monitoring value, and isolation status.
Constraints for Knowledge Base Retrieval and Recall
The data characteristics of this category create multiple constraints for retrieval and recall. Multi-source data mixes real-time monitoring values, static regulatory documents, and formatted work permits. The system must balance structured field matching and unstructured text semantic retrieval. The high-frequency update feature requires the retrieval system to support incremental indexing triggered by operation nodes and batch rebuilding capabilities. Diverse document types include fixed-format work permits, free-text risk records, and ledger data. The system must adapt chunking and recall logic for different document structures. Additionally, due to high operational risks and severe consequences of errors, retrieval and recall must prioritize high-priority fields to avoid missing key compliance requirements.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Filters low-relevance non-compliant content to avoid irrelevant documents interfering with operational risk assessment |
limit | Top 10 | Adapts to time constraints of pre-operation review, returns the most relevant core compliance requirements and operation references |
searchMode | mixedRecall | Balances keyword matching for regulatory standards and semantic association for work permits, covering different types of retrieval needs |
usingReRank | Enabled | FastGPT v4.17.0 re-ranking function optimizes result order, ensuring key qualifications and isolation requirements appear first |
datasetSearchUsingExtensionQuery | Enabled | Can supplement implicit needs of operation scenarios via extended queries, for example, expanding "hot work" to include compliance requirements and testing standards |
collectionIds | Bind the ID list of the exclusive safety, environmental protection and special operations management dataset | Isolate knowledge base content from unrelated businesses, preventing retrieval results from mixing with production quality documents |
Three Common Mistakes
- Phenomenon: After batch rebuilding knowledge base indexes, some work permits and monitoring records are not loaded correctly. Cause: Failed to specify the
collectionIdsof the corresponding safety, environmental protection and special operations management dataset, causing the batch task to cover unrelated knowledge base content. - Phenomenon: Outdated, homogeneous compliance documents appear before documents with more recent update times in retrieval results. Cause: Did not enable weight adjustment based on document update time, or the re-ranking link did not prioritize time dimension matching.
- Phenomenon: A large number of irrelevant production quality documents are returned when retrieving compliance requirements related to operations. Cause: Did not bind the exclusive dataset, so the retrieval scope includes knowledge base content from non-target categories.
How to Confirm Proper Configuration
- Check that
collectionIdsonly bind datasets related to safety, environmental protection and special operations management, ensuring the retrieval scope does not include other business documents. - Perform a single retrieval test to verify whether the results prioritize compliance documents with more recent update times, confirming that the re-ranking and weight logic are effective.
- Initiate a batch index rebuilding task, and check whether the task log covers all target document types with no error prompts.
- Adjust the
similaritythreshold to the interval suitable for the scenario, verifying that the relevance of retrieval results meets the needs of operation review.
