What This Category of Data Looks Like
Data for this category comes from the centralized treasury payment system, integrated budget management system, electronic invoice platform, and contract management system. The update frequency is daily. Daily processed documents include payment applications, fund appropriation plans, invoices, contracts, acceptance reports, reimbursement approval forms, and payment vouchers. All these documents are generated around the execution link of individual fiscal fund payments, and serve the daily audit work of budget unit finance, treasury payment center finance audit posts, and competent department finance audit posts.
Constraints Imposed on Knowledge Base Retrieval and Recall
Multi-source heterogeneous data sources require the retrieval link to adapt to document formats exported by different systems. This prevents content parsing errors caused by format differences. Daily updated data sources require the knowledge base synchronization frequency to match the business update rhythm. This ensures recalled content includes the latest payment and compliance information. The feature that individual businesses are linked to multiple types of documents requires retrieval to accurately match all associated content of the corresponding chain. Broadly matching a single field is not sufficient. The high compliance risk of error consequences requires retrieval confidence to be controlled within a reasonable range. This avoids low-relevance content interfering with audit judgments. The party building learning Q&A scenario further requires retrieval to simultaneously associate business compliance documents and party building-related financial discipline learning content.
Recommended Configuration Parameters
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Matches the accuracy requirements of centralized treasury payment business, avoids low-relevance bills or contract content interfering with audits |
limit | Top 8–12 entries | Covers multiple types of documents involved in a single payment, while controlling the number of retrieval returns to avoid timeouts |
searchMode | hybrid | Combines keyword and semantic retrieval, adapts to multi-source heterogeneous business documents and party building learning text |
usingReRank | Enabled | Reranks multi-document recall results, improves ranking accuracy for party building compliance and business matching |
datasetSearchUsingExtensionQuery | Enabled | Based on the party building learning Q&A scenario, automatically expands query terms related to financial discipline and party building requirements |
collectionIds | Collection IDs corresponding to the business document library and party building knowledge base | Separates business data and party building learning content, ensuring precise retrieval scope |
Three Common Configuration Mistakes
- Phenomenon: After enabling
usingReRankanddatasetSearchUsingExtensionQuery, retrieval response times out, with return latency exceeding 30 seconds. Cause: The number of returned entries forlimitis not restricted, or a reasonablesimilaritythreshold is not configured. This results in too many redundant documents being recalled to participate in reranking and extended query processing. - Phenomenon: Non-current business category documents are mixed in retrieval results, such as budget final account content. Cause: The
collectionIdsretrieval range is not configured, resulting in cross-category data being recalled. - Phenomenon: The title and content of uploaded HTML format documents are not correctly indexed. Cause: An HTML-adapted retrieval preprocessing process is not used, or parameter configuration of the document upload interface is not correctly invoked.
How to Verify Proper Configuration
- View the knowledge base synchronization logs of FastGPT v4.17.0, confirm that daily updated business documents and party building content have been successfully synchronized to the corresponding collections.
- Initiate a query for a simulated payment application, check that the retrieval results include corresponding bills, contracts, and party building financial discipline related content.
- Test the response time after enabling
usingReRankanddatasetSearchUsingExtensionQuery, confirm that it meets the latency requirements of the business scenario. - Check that the number of retrieval returned results matches the value configured for
limit.
