What this category of data looks like
Daily processing documents for this category include basic government service item catalogs, implementation lists, service guidelines, standard material catalogs, flowcharts, and frequently asked questions. Data sources are the national basic government service item catalog, administrative licensing item list, power and responsibility list, and local government service item databases, with a monthly update frequency. A single document usually contains standardized fields such as item code, item name, acceptance conditions, application material list, and handling process. Some cross-level items must match the unified field requirements of the superior catalog to ensure consistent service caliber across regions.
What constraints these characteristics impose on the "knowledge base retrieval and recall" link
Monthly updated data sources require the knowledge base to complete full data synchronization on a fixed cycle to avoid content lag. Standardized document fields and cross-level matching requirements mean retrieval and recall must prioritize matching core fields such as item code and acceptance conditions to ensure consistent caliber for cross-level items. The standardized structure of a single document also means chunked retrieval needs to balance field integrity, preventing loss of associated application materials and handling process information after splitting. Internal maintenance positioning means retrieval only needs to cover rule-based documents related to government service items, without processing individual applicant's specific application requests.
How to configure settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | This category requires matching standardized government service item fields, filtering low-relevance content to avoid inconsistent service caliber issues |
limit | Top 10 results | The monthly updated dataset has a moderate scale; the top 10 results can cover core comparison reference content such as superior catalogs and local implementation lists |
usingReRank | Enabled | Standardized documents have strong field associations, and reranking can improve the sorting priority of core content such as acceptance conditions and application materials |
datasetSearchUsingExtensionQuery | Enabled | Extended queries can supplement standardized keywords such as item code and item name, improving the accuracy of cross-level catalog matching |
collectionIds | Fill in the collection ID of the corresponding government service item knowledge base | Ensure retrieval only covers the government service item catalog and service guideline dataset exclusive to this category, avoiding mixing in irrelevant content |
Three common misconfigurations
- Phenomenon: When uploading large government service item documents to the knowledge base, the interface shows an upload timeout, but the background upload task actually completes normally, and the file is displayed after a period of time. Cause: The upload timeout threshold is not adjusted for the single-file size of government documents, and the default threshold is insufficient for large-sized service guidelines or catalog documents.
- Phenomenon: Retrieval results contain a large amount of content unrelated to government service items, with insufficient field matching. Cause: A reasonable
similaritythreshold is not set, ordatasetSearchUsingExtensionQueryis not enabled, resulting in low-relevance content being recalled. - Phenomenon: During multi-round retrieval, subsequent queries do not associate with the currently maintained item context, returning old catalog content. Cause: Session context retention rules are not configured, or the retrieval scope is not limited to the item collection corresponding to the current session, resulting in recall of old data across sessions.
How to confirm the configuration is correct
- Upload a test service guideline document containing complete item fields, perform a retrieval test, and check whether the relevance scores of the returned results meet the preset threshold requirements.
- Enter keywords from the superior government service item catalog to initiate retrieval, and check whether the returned results include corresponding implementation lists, standard material catalogs and other associated documents.
- Upload a single large-sized test document, confirm that the interface can normally display upload progress and completion status, with no timeout errors.
- Initiate two consecutive retrieval queries, check whether the second query can associate with the item context from the first query, and return results matching the currently maintained items.
