What the Data for This Category Looks Like
The data for this category comes from China’s national government procurement website, local government procurement websites, the fiscal integration system, the procurer’s budget system, and supplier credit records. The update frequency is daily. Daily documents include procurement requirements, procurement plans, bidding documents, tender documents, bid evaluation reports, winning bid announcements, procurement contracts, and question-and-response documents. Four typical stakeholders are involved: procuring entities, the finance department’s government procurement supervision division, procurement agencies, and evaluation experts. Most documents contain standardized fields such as procurement numbers, procurement content, qualification requirements, and scoring rules. The primary format is structured documents published by official authorities.
Constraints Imposed on Knowledge Base Retrieval and Recall
The daily data update requirement means the retrieval pipeline must support near-real-time data source synchronization. This prevents retrieving expired regulatory or procurement-related content. Document structures vary significantly across multiple sources. Core retrieval terms such as procurement numbers and scoring methods have different distribution characteristics across different documents. This requires adapting differentiated recall weights. Structured documents published by official authorities require prioritizing matching structured fields during retrieval. This improves retrieval accuracy. Unlike engineering bidding documents, government procurement documents have higher compliance requirements. Retrieval and recall must strictly follow business scenario constraints to avoid missing key clauses.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Meets the rigor requirements of government procurement documents, filters low-relevance non-official content |
limit | Top 10 entries | Balances retrieved information volume and retrieval latency, aligns with the reference needs of single-draft document creation |
searchMode | vector+keyword | Balances semantic recall and structured field matching, adapts to multiple types of government procurement documents |
usingReRank | Enabled | Re-ranks retrieval results, prioritizes displaying high-value content related to procurement requirements and scoring methods |
datasetSearchUsingExtensionQuery | Enabled | Automatically expands retrieval terms, covers exclusive fields such as procurement numbers and supplier credit ratings |
collectionIds | Collection ID corresponding to the government procurement-specific knowledge base | Limits retrieval scope, avoids mixing in data unrelated to this category |
Three Common Configuration Errors
- Symptom: Calling the knowledge base file list interface returns an empty array or 403 status code. Cause: Request parameters are not correctly concatenated, or access to the corresponding government procurement knowledge base collection is not authorized.
- Symptom: An incorrect format prompt appears when uploading a DOCX document containing images. Cause: The document image parsing function is not enabled, or the knowledge base is not adapted to handle DOCX formats with embedded images.
- Symptom: Retrieved results do not include the latest winning bid announcements or question-and-response documents. Cause: Daily incremental data source synchronization is not configured, so retrieval only uses offline historical data and does not synchronize official content updated on the current day.
How to Verify Successful Configuration
- Enter keywords related to procurement requirements to perform a retrieval test, and confirm whether the returned results include category-specific documents such as procurement plans and bidding documents.
- Upload a government procurement DOCX template document with embedded images, and confirm that the upload is successful and no format error prompts are displayed.
- View the knowledge base synchronization log, and confirm that the daily incremental synchronization task has been executed normally with no failed records.
- Call the knowledge base file list interface, and verify that the returned file list includes uploaded government procurement-related documents with no omissions.
