What the data for this category looks like
The data for this category comes from the enterprise registration full-process electronic system, the national enterprise credit information publicity system, the electronic business license system, and the residence information database. The update frequency is daily. Daily processed documents include standardized materials such as establishment registration applications, articles of association, shareholder resolutions, residence certificates, business licenses, and food business license applications. Fields include subject name, residence address, shareholder information, license type, application status, and others. The overall format is uniform and standardized, with no large volume of unstructured free text.
Constraints imposed on knowledge base retrieval and recall by these characteristics
The daily update requirement for the data means the retrieval and recall link must support incremental synchronization and real-time verification. This ensures returned registration information and licensing rules use the latest versions. The standardized document structure and fixed fields require retrieval to accurately match core fields such as subject name and residence address. This avoids invalid results caused by fuzzy matching. Core business links rely on name and residence verification and license condition judgment, so retrieval must prioritize rule-related documents. This allows employees to quickly access accurate reference materials when processing applications, and reduces the risk of registration rejection.
How to Configure
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Match core fields such as subject name and residence address with high similarity to filter irrelevant non-target documents |
limit | Top 8 entries | Align with the upper limit of materials for single business processing, preventing excessive recalled documents from causing context overload |
searchMode | Hybrid retrieval | Balance precise matching of standardized fields and semantic recall of business rules to cover different types of business queries |
usingReRank | Enabled | Reorder initially recalled results to prioritize documents most relevant to license conditions and verification requirements |
datasetSearchUsingExtensionQuery | Enabled | Expand synonyms for user business questions to cover wording differences such as "residence certificate" and "business place certificate" |
collectionIds | Configured by business group | Only associate knowledge base collections related to registration and licensing, eliminating irrelevant documents that could interfere with retrieval results |
Three Common Mistakes
- The knowledge base functions normally during debugging, but an error
common:core.chatoccurs after going live. The cause is failure to configure knowledge base access permissions, or inconsistency between the knowledge base collection ID in the online environment and the debugging environment. - Only simple parameters can be adjusted, and reference templates and prompt words cannot be customized. The cause is use of a FastGPT version below v4.17.0; advanced configuration functions require the corresponding version support.
- After configuring hybrid retrieval with
similarityset to 0.8,limitset to 1500, and enabling reranking, the number of recalled results exceeds expectations. The cause is failure to restrict thecollectionIdsrange, leading to recall of a large number of irrelevant knowledge base documents that exceed the context carrying limit.
How to Confirm Configuration is Complete
- Check that knowledge base collection IDs only include registration and licensing related documents, to prevent irrelevant content from being included in the retrieval scope.
- Verify that the switch states of
usingReRankanddatasetSearchUsingExtensionQuerymatch the configured settings. Test queries can be used to check whether the sorting of returned results conforms to business logic. - Test core business questions such as "preconditions for food business license", confirm that recalled documents are corresponding business materials, and that similarity values fall within the preset range.
- Review system retrieval logs to confirm that request parameters match configuration items, with no missing or incorrect configurations.
