What the data for this category looks like
Data for this category mainly comes from the state-owned assets supervision and administration investment supervision system, enterprise ERP and project management systems, industry market data, audit and financial statements, with a quarterly update frequency. Daily documents include annual investment plans, project proposals, feasibility study reports, due diligence reports, asset appraisal reports, and post-investment evaluation reports. These documents cover the full process of project approval, investment decision material preparation, and post-launch evaluation. Most data fields include project number, investment amount, approval node, post-evaluation score, and similar items. There is no unified standardized format, and the length of individual documents varies greatly.
What constraints these characteristics impose on knowledge base retrieval and recall
The quarterly updated data source requires the retrieval system to support flexible switching between incremental synchronization and full refresh. This aligns with the regular update rhythm of state-owned asset projects, and avoids excessive system resource occupation from full recall. Multiple types of non-standard documents require adaptation to different chunking strategies, to prevent damage to business logic from long document splitting and maintain retrieval result completeness. Project-related fields have high professionality, so recall results must be strongly linked to the business scenarios of project approval and post-evaluation. The system must also support retrieval of compliance content related to state-owned asset supervision. In addition, the large variation in document length requires adjusting the recall context length to match the information density of different documents, avoiding redundant content or missing information.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.72–0.80 | Adapts to semantic matching accuracy for professional project documents, filters low-relevance party building learning Q&A content, and complies with FastGPT v4.17.0 parameter calling rules |
limit | Top 8–12 entries | Balances the information volume of investment decision-making meeting materials and retrieval response speed, and meets the material volume requirements for state-owned asset project review |
searchMode | vector + hybrid | Balances semantic matching and precise keyword recall, adapting to retrieval needs for professional terminology and compliance fields |
usingReRank | Enabled | Performs secondary sorting on recall results to further filter irrelevant content and focus on party building related documents linked to investment projects |
datasetSearchUsingExtensionQuery | Enabled | Generates extended queries based on original questions, covering extended retrieval needs for policy-linked investment projects during party building learning |
collectionIds | Bind exclusive datasets by business domain | Isolates investment project knowledge base data from other categories, avoiding cross-domain retrieval interference with business processes |
Three Common Mistakes
- Debugging preview works normally but self-hosted page cannot search: The symptom is that retrieval results are normal during the preview phase, but no results are returned or an empty list is returned after deployment to a self-hosted page. The cause is failure to correctly bind the business-exclusive
collectionIds, or failure to carry correct dataset permission parameters during page calls. - Knowledge base cannot import Markdown files: The symptom is that an unsupported format prompt appears when uploading Markdown-format project proposals or post-evaluation reports. The cause is failure to enable automatic chunking adaptation for Markdown documents, or parsing failure caused by unescaped special characters in the document.
- All images in cloud knowledge base report errors: The symptom is that embedded project report images in retrieval results fail to load normally. The cause is failure to configure the knowledge base image resource hosting path, or image links not adapting to the internal network access rules of state-owned asset systems.
How to Verify Configuration Completion
- Check the dataset binding relationship, confirm that the
collectionIdspassed during interface calls match the business-exclusive datasets. - Initiate a simulated retrieval, verify that returned results include category-exclusive documents such as project proposals and post-evaluation reports, and no irrelevant non-investment content is included.
- Test the incremental synchronization function, confirm that quarterly updated data sources can normally trigger knowledge base refresh, with no synchronization timeouts or data loss.
- After enabling
usingReRank, compare the relevance of retrieval results before and after reranking, ensuring highly matched investment project documents appear at the top.
