What this category of data consists of
This category of data sources includes the national integrated government service platform item database, administrative licensing item list, departmental business approval systems, and electronic certificate database. The update frequency is daily. Daily documents are built around individual administrative licensing items, covering types such as service guides, application forms, commitment letters, acceptance notices, correction notification letters, administrative licensing decision letters, and licenses. They include standardized fields such as item name, handling conditions, required material list, and approval process. All content follows unified government service format specifications.
What constraints these characteristics impose on the knowledge base retrieval and recall link
Data sources cover multiple government systems and are updated daily. This requires the retrieval link to support cross-source data integration and near-real-time synchronization, to ensure recalled content is the latest administrative licensing-related information. Document types include structured material lists, item codes, and unstructured approval documents. This requires retrieval to adapt to content in different formats. At the same time, the retrieval scope must be strictly bounded by legally defined licensing items, to avoid irrelevant cross-item content being included. Recalled results must match the item’s setting basis and handling conditions to meet government service compliance requirements.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Handling conditions and material requirements for administrative licensing items require high matching accuracy to prevent irrelevant content from being included in the approval process |
limit | Top 8 entries | The number of administrative licensing-related documents is relatively fixed. Too many results will exceed the context window, while too few will fail to cover complete handling requirements |
searchMode | vector+keyword | Structured item codes and material lists are suitable for keyword retrieval, while unstructured service guides are suitable for semantic retrieval |
usingReRank | Enabled | Recalled results need to be sorted by relevance to ensure the most matching handling requirements and material lists are returned first |
datasetSearchUsingExtensionQuery | Enabled | User handling queries can be expanded to include item identifiers, improving the matching degree between recalled results and specific administrative licensing items |
collectionIds | Bind exclusive knowledge base collections corresponding to administrative licensing items | Strictly limit the retrieval scope to prevent irrelevant content from cross-administrative licensing items from interfering with retrieval results |
Three common configuration mistakes
- Phenomenon: Retrieved content does not match the user’s administrative licensing handling query at all. For example, asking about enterprise establishment licensing but returning real estate registration procedures. Cause:
collectionIdsis not configured to limit the retrieval scope, resulting in recalled documents from cross-item sources. - Phenomenon: Semantic retrieval score shows 0.92, but the returned content does not mention the specific material list required for handling. Cause: The
similaritythreshold is set too low, resulting in semantically similar but non-matching items being classified as high-match results. - Phenomenon: Retrieval results do not include the latest correction notification letter format. Cause: The knowledge base has not synchronized data at the daily update frequency, resulting in recalled expired approval documents.
How to confirm the configuration is correctly set
- Access the FastGPT v4.17.0 knowledge base management interface, confirm that
collectionIdsonly binds document collections exclusive to administrative licensing items. - Initiate a test query, enter a specific administrative licensing item name and handling question, verify that the item code in the recalled results matches the query content.
- Adjust the
similaritythreshold, test recalled results under different thresholds, confirm that the matching degree of returned content meets business compliance requirements. - Check the knowledge base synchronization logs, confirm that data updates are completed daily to ensure recalled content is the latest version.
