What the Data for This Category Looks Like
The declaration materials and case review data for power grid enterprises mainly comes from power engineering project initiation declaration documents, transmission and distribution project case files, and qualification review and filing materials. The update rhythm is adjusted according to the project cycle: bulk imports occur during the project initiation phase, and incremental updates are made during daily supplementary document submissions. Most documents are in PDF or Word format, with fixed structured fields: project number, declaring unit, voltage level, review submission date, review node, attachment list. Unstructured content includes project feasibility descriptions, on-site inspection records, etc. Units use industry-standard power units such as kilovolts (kV) and megawatts (MW).
Constraints on the Knowledge Base Retrieval and Recall Link
The characteristics of power grid enterprise declaration materials and case review data impose clear constraints on the retrieval and recall process. Multi-page long documents require segment length to match the semantic integrity of professional texts, to avoid splitting professional terms or compliance clauses. Mixed structured and unstructured content requires retrieval to support both keyword matching for structured fields and vector matching for text content. The batch update feature requires the knowledge base to support batch synchronization and incremental updates, to avoid excessive time consumption from single synchronization. The relevance of review nodes requires retrieval results to be associated with the historical review case files of the corresponding project to ensure coherent context.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
similarity | 0.72–0.85 | Meets the strict compliance requirements for power grid declaration materials, filters low-relevance non-power documents |
limit | Top 8–12 entries | Adapts to the review context length of a single declaration material, avoiding exceeding the model's token limit |
usingReRank | Enabled | Power grid documents mostly contain professional terms, re-ranking can improve the sorting accuracy of professional content |
searchMode | vector+keyword | Balances retrieval for structured fields such as project number and unstructured content |
datasetSearchUsingExtensionQuery | Disabled | Declaration materials mostly follow fixed formats, no need for additional query expansion, which avoids introducing irrelevant content |
collectionIds | Bind to the exclusive collection of corresponding power grid declaration case files | Isolates knowledge bases for different projects, avoiding cross-project retrieval interference |
Three Common Misconfigurations
- Phenomenon: Retrieval response times out beyond 30 seconds, and the number of results is insufficient. Cause:
usingReRankis enabled without limiting the re-ranking count, and thelimitparameter is not adjusted to fit the length of power grid documents. - Phenomenon: System logs show that the model used for retrieval does not match the configured model. Cause: The declaration case file knowledge base is not bound to the question optimization model, and a mismatched model is called across knowledge bases.
- Phenomenon: The AI generates content beyond the scope of the knowledge base. Cause: The rule to only recall content matched by the knowledge base is not configured, causing the model to automatically generate supplementary content.
How to Verify Proper Configuration
A single standard power grid declaration material may be uploaded, and retrieval results verified to confirm they include the core content of the material and associated historical case files. System logs may be reviewed to confirm the model used for retrieval matches the configured model, with no cross-model calls occurring. Questions exceeding the knowledge base scope may be tested to verify only prompts for no matching content are returned, with no automatically generated content present. The similarity parameter may be adjusted, and retrieval results checked to confirm their relevance meets expectations, with no low-matching irrelevant documents included.
