What this category’s data looks like
Data for nuclear power operation policy and regulatory basis primarily comes from nuclear power operation and maintenance regulations issued by the National Nuclear Safety Administration and the National Energy Administration, internal operation specifications of the group, and industry standard documents. Full updates are triggered when major policies are revised. Routine maintenance follows a quarterly synchronization schedule. Each document is a single regulation, and includes fields such as regulation number, effective date, applicable unit type, clause content, and implementation details. Field units use standardized formats including "Article X", "YYYY-MM-DD", and "Unit X". Most individual documents exceed 5000 characters in length.
What constraints do these characteristics impose on the knowledge base retrieval and recall link?
Long individual documents require preserving clause integrity during chunking, to avoid splitting that breaks policy logic. Fields include standardized regulation numbers and effective dates. Retrieval must support precise field matching, otherwise irrelevant regulations may be retrieved. Update frequency is low, but updated content has strong compliance requirements. Retrieval scope must only cover authorized latest policy versions. Nuclear power policy terms are precise. Extended queries may cause semantic deviation. The degree of retrieval generalization must be strictly controlled to ensure accuracy of compliance queries.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Nuclear power policies require high-precision matching to avoid retrieving irrelevant compliance clauses, ensuring business operations comply with regulatory requirements |
limit | Top 8 entries | No more than 8 entries retrieved per round of search, adapting to batch associated query needs of policy documents, avoiding overly long contexts that exceed model processing limits |
searchMode | Precise matching | Prioritize matching precise fields such as regulation numbers and clause numbers, ensuring compliance relevance between search results and input queries |
usingReRank | Enabled | Reorder retrieved results by compliance relevance, ensuring core policy clauses are displayed first and improving efficiency of compliance queries |
datasetSearchUsingExtensionQuery | Disabled | Nuclear power policy terms are precise, avoiding semantic deviation caused by extended queries to ensure accuracy of retrieval results |
collectionIds | Bind dedicated dataset ID for nuclear power policies | Isolate knowledge base data from other categories, ensuring retrieval scope only covers policy documents related to nuclear power operations |
Three Common Mistakes
- Symptom: A
timeout of 60000ms exceedederror occurs when deleting a folder containing tens of thousands of policy documents in the knowledge base. Cause: Batch deletion operations are not performed in batches for large folders, and single batch processing exceeds the system timeout threshold. - Symptom: Some policy attachment images in knowledge base search results cannot be displayed normally. Cause: Image links in original policy documents are internal private network addresses, and no external network access permissions are configured or image resources are not synchronized to the knowledge base storage bucket.
- Symptom: No corresponding policy clauses are returned when searching for nuclear power professional terms such as "nuclear island operation and maintenance". Cause: A general knowledge base is used directly instead of a professional term library, and no term mapping logic is configured, resulting in insufficient term matching accuracy.
How to Confirm Configuration is Correct
- Perform a single policy retrieval test, input a query containing a regulation number or professional term, check the matching degree of retrieved results, and adjust the
similarityvalue to the range that meets business compliance requirements. - Upload a nuclear power policy test document containing images and tables, verify that images load normally in search results, and confirm that storage permissions and resource synchronization configurations are correct.
- Attempt to batch delete a test folder containing thousands of documents, observe whether a timeout error occurs, and adjust the batch processing threshold to adapt to system performance.
- Input nuclear power professional terms, check whether retrieved results include corresponding policy clauses, and confirm that the term matching logic is correctly configured.
