What the Data for This Category Looks Like
Power grid enterprise internal office and employee service data sources include operation and maintenance procedures, equipment ledger documents, internal collaboration platform documents, post training manuals, dispatch instruction specifications, and more. Update cycles are adjusted per business cycles: equipment ledgers are updated monthly, operation procedures are revised quarterly, and training manuals are updated dynamically based on post requirements. Document types include long-text professional procedures, structured parameter tables, and guides with operation step illustrations. Fields include equipment number, rated voltage, operation and maintenance cycle, response time limit, and more. Units include kilovolts, ten thousand kilowatts, hours, number of operations, and more.
Constraints These Characteristics Impose on Knowledge Base Retrieval and Recall
Failing to split long-text professional procedures logically results in retrieved fragments that do not cover complete operation steps. Extracting only plain text from structured equipment ledger tables loses the correspondence between fields and values, reducing retrieval accuracy. Extracting only text from illustrated operation guides omits critical visual guidance. Failing to synchronize frequently updated ledgers in a timely manner leads to retrieval of outdated equipment parameters. Internal documents use post-based permission settings, requiring filtering of non-authorized retrieved content to prevent sensitive information leaks. These requirements mean the retrieval and recall link must support long-text chunking, structured data parsing, image association processing, incremental synchronization, and permission control.

How to Set the Configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Adapts to the density of power grid professional terminology, filters low-relevance general text, and retains core business content |
limit | Top 8 entries | Matches the single-batch recall volume for internal work orders and equipment ledgers, preventing context overload that disrupts response logic |
searchMode | Full-text retrieval | Adapts to long-text operation procedures and illustrated operation documents, enabling recall covering full document content |
usingReRank | Enabled | Performs secondary ranking on retrieved professional terminology fragments to improve the ability to accurately match professional queries |
datasetSearchUsingExtensionQuery | Enabled | Generates extended query terms for power grid professional terminology, covering synonyms, abbreviations, and industry-standard expressions |
collectionIds | Bind corresponding collections by department/post | Matches internal post permission controls, only retrieving documents accessible to the corresponding role |
Three Common Misconfigurations
- Phenomenon: After importing DOCX-format operation procedures or Excel-format equipment ledgers, retrieval results show field misalignment or professional term truncation. Cause: Reasonable chunking and structured parsing configurations are not enabled, and only plain text is extracted, resulting in loss of document structure.
- Phenomenon: Images in Feishu documents stored in the knowledge base cannot be displayed as images in retrieval results. Cause: Image association retrieval configuration is not enabled, only the text content of the document is extracted, and the association relationship of image links is not retained.
- Phenomenon: After private deployment, clicking the new knowledge base button triggers an error, and the interface displays a parameter exception prompt. Cause: The dataset storage path corresponding to
collectionIdsis not configured correctly, causing the system to fail to complete the initial creation of the dataset.
How to Verify Successful Configuration
- Upload an equipment ledger document containing structured tables, retrieve the corresponding keyword, and check whether the retrieval results retain the correspondence between equipment numbers and parameter values.
- Upload a Feishu document with operation step illustrations, retrieve the corresponding operation keyword, and check whether the retrieval results include accessible image links.
- Adjust the value range of the
similarityparameter, and verify whether the relevance of retrieval results changes as expected with the threshold. - Assign permissions by department using
collectionIds, switch roles, and check whether the range of retrieved documents matches the business content of the corresponding department.
