What this category of data looks like
Data related to nuclear power operation business process guidance primarily comes from officially released operating procedures, business approval manuals, on-site work permit documents, and post responsibility lists. Data sources are safety management departments and process control teams of nuclear power operation units. Updates are synchronized when major equipment modifications or national nuclear safety regulatory requirements change, and quarterly updates are made for daily business process adjustments. Documents use a chapter-based structure, with fixed fields including process number, responsible department, approval time limit (unit: working days), required material list, and exception handling steps. The length of a single document typically ranges from 800 to 2000 characters.
What constraints do these characteristics impose on the knowledge base retrieval and recall link
The chapter-based structure requires retrieval to retain the logical coherence of the process, avoiding overly fragmented chunks that break step continuity. Information such as approval time limits and responsible departments in fixed fields must be accurately matched, with no semantic deviation. The periodic update frequency requires retrieval to prioritize the most recently updated document versions, avoiding expired process guidance. Business process questions mostly focus on queries about individual process nodes. Retrieval must quickly locate content in the corresponding chapter, while excluding unrelated equipment maintenance or safety training documents.
How to set the configuration
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Nuclear power business documents use precise terminology, so a high matching threshold is needed to filter irrelevant process content and avoid incorrect guidance |
limit | Top 6 results | Standard steps for nuclear power business process guidance typically range from 5 to 7 steps. Retrieving too many results will cause context overload and reduce guidance accuracy |
searchMode | keyword+vector | Business processes have both clear keywords (such as "unloading approval") and semantic connections between step logic. The hybrid mode covers more relevant scenarios |
usingReRank | Enabled | The order of process steps is critical for business guidance. Reranking optimizes result relevance sorting to ensure key steps are returned first |
datasetSearchUsingExtensionQuery | Enabled | Business process questions often include position or device-specific terms. Extended queries can cover more documents that contain these qualifying conditions |
collectionIds | Exclusive collection ID for nuclear power business process documents | Accurately limit the retrieval scope, avoid mixing documents from other categories, and ensure retrieved results are strongly related to business processes |
Three common mistakes
- Symptom: The knowledge base collection tag entry is not visible in the trial backend. Cause: The current operating account has not been added to the accessible role list of the corresponding dataset.
- Symptom: Irrelevant non-business process document fragments appear in retrieval results. Cause: No
collectionIdsconfiguration was used to limit the retrieval scope, resulting in content from other unrelated datasets being retrieved. - Symptom: Knowledge base retrieval is not triggered in the workflow, and AI-generated chat content is returned directly. Cause: The exclusive nuclear power business process dataset was not associated with the workflow node.
How to confirm the configuration is correct
- Access the FastGPT v4.17.0 backend dataset management page, confirm that the exclusive nuclear power business process dataset has been created and the correct
collectionIdshave been configured. - Initiate a test query, enter a business process-related question, and check whether the matching score of the retrieval results falls within the configured
similarityrange. - Check the number of retrieved results, confirm that it does not exceed the configured
limitquantity. - Review the workflow node, confirm that the
usingReRankanddatasetSearchUsingExtensionQueryparameters have been enabled.
