What this category of data looks like
This category of data covers full-process documents related to market entity registration and licensing, including establishment registration applications, articles of association, shareholder resolutions, domicile certificates, business licenses, food business license applications, and more. Data sources include the full-process electronic enterprise registration system, the national enterprise credit information publicity system, the electronic business license system, and the domicile information database. The update frequency is daily. Data fields mostly involve entity name, unified social credit code, domicile address, license type, application material list, and no additional custom units. Most documents are structured forms and standardized text formats.
What constraints these characteristics impose on knowledge base retrieval and recall
Most data sources are official business systems, so data source consistency must be ensured during retrieval to avoid cross-system data conflicts. The daily update feature requires the retrieval pipeline to support flexible configuration of incremental synchronization and full refresh, to prevent data lag from impacting policy basis matching. Most documents are structured forms, so field-level precise matching should be prioritized during retrieval. There are many license type and subject qualification fields, so the retrieval scope must be limited to registration and licensing-related datasets to avoid mixing in business data from other categories.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Meets the precision requirements for matching policy basis, avoids low-similarity irrelevant documents interfering with approval judgments |
limit | Top 8–12 results | The number of documents retrieved per call adapts to the multi-basis verification needs of registration and licensing, avoids excessive context overload |
searchMode | keyword + vector | Balances keyword matching for structured fields and semantic recall for unstructured text, covers both forms and policy documents |
usingReRank | Enabled | Re-ranks retrieved results to prioritize documents most relevant to policy basis Q&A |
datasetSearchUsingExtensionQuery | Enabled | Optimizes user questions through extension, improves recall precision for policy clauses and license conditions |
collectionIds | Specify exclusive dataset IDs for registration and licensing | Limits retrieval scope to the exclusive knowledge base for this category, avoids mixing in irrelevant data from other business systems |
Three common misconfigurations
- Phenomenon: No optional values appear when referencing variables after selecting a knowledge base. Cause: Variable mapping was not enabled in the dataset configuration, or the corresponding field was not set as a referenceable attribute.
- Phenomenon: Large discrepancies exist between online chat and API call results, with abnormal results when the API is called with
stream: falseanddetail: true. Cause: Retrieval parameters for the API and frontend were not unified, or the correct dataset ID and retrieval configuration were not passed during the API call. - Phenomenon: After upgrading to FastGPT v4.17.0, previously indexed knowledge bases no longer support vector retrieval, with no search results returned. Cause: The vector index format changed after the version upgrade, and full index synchronization was not re-run.
How to confirm the configuration is properly set
- Manually input a typical registration and licensing policy question, and verify that the retrieval results include exclusive documents for this category.
- Check that
collectionIdsin the dataset configuration only includes knowledge base collections related to registration and licensing. - Verify that the
similarityretrieval parameter value meets the precision requirements of the business scenario, and adjust through multiple rounds of testing. - Confirm that the
usingReRankfunction is enabled, and the re-ranked result order follows the priority logic of policy basis.
