What the Data for This Category Looks Like
The data for this category comes from the national petition information system, local petition systems, the 12345 citizen hotline, grassroots governance platforms, and historical petition archives. The update frequency is daily. Daily documents include petition registration forms, acceptance notices, transfer and assignment letters, handling opinions, review and re-examination applications, resolution plans, and similar materials. Fields cover core business information such as the requesting subject, matter type, handling progress, policy basis, review results, and more. The length of individual documents varies widely, ranging from short registration forms to detailed handling opinion documents.
What Constraints These Characteristics Impose on the Knowledge Base Retrieval and Recall Link
Data sources are scattered across multiple government systems, and cross-platform document formats have both structured and unstructured differences, which creates requirements for retrieval adaptability. The daily update frequency requires the retrieval and recall link to support incremental synchronization logic to ensure data timeliness. The wide range of daily document lengths, from short registration forms to detailed handling opinions, requires matching appropriate chunking rules to retain complete business information. Fields cover demands, progress, review results, and similar attributes, which requires support for precise recall based on business attributes. Relying solely on keyword matching cannot meet the business requirements for precise recall.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Petition matters require precise matching of policy basis and handling procedures. This interval can filter irrelevant content while retaining core relevant results |
limit | Top 8 entries | Petition handling needs to balance comprehensiveness and efficiency. 8 results can cover handling reference materials for different stages |
searchMode | semantic_search | Adapts to the semantic understanding needs of petition matters, supporting precise matching of policy clauses and demands |
usingReRank | Enabled | For documents with wide length ranges, re-ranking can improve the sorting priority of highly relevant results |
datasetSearchUsingExtensionQuery | Enabled | For colloquial expressions of petition demands, optimize and expand search terms to cover potential policy basis |
collectionIds | Configured by business grouping | Distinguish different document collections such as petition registration, handling, review, and similar categories to achieve precise recall |
Three Common Configuration Mistakes
- Phenomenon: An upload failure prompt appears when uploading documents such as petition registration forms and handling opinions. Single files or batch multiple files cannot be uploaded. Cause: The upload permission for the corresponding document collection is not configured, or the document contains encrypted content that cannot be parsed.
- Phenomenon: When searching for petition policy basis, the returned handling opinion content is incomplete, with key clauses truncated. Cause: Segmentation enhancement processing is not enabled, and direct segmentation causes core business information of long documents to be split and lost.
- Phenomenon: Retrieval response times out, and system hard disk IO occupancy remains high. Cause: A reasonable
limitparameter is not set, recalling too many irrelevant documents leads to excessive computing resource occupancy. The incremental synchronization logic adapted to daily updates is not used, leading to full retrieval occupying a large amount of hard disk resources.
How to Verify Correct Configuration
- Upload a typical petition handling opinion document, check whether it can be successfully synchronized to the specified document collection, and confirm that the upload permission and collection configuration are correct.
- Enter a typical petition demand, check the relevance and completeness of the retrieval results, and adjust relevant parameters to the range that meets business expectations.
- View the retrieval response time and system resource occupancy, and confirm that the parameter configuration and incremental synchronization logic are adapted to the business update frequency.
- Verify that the retrieval results include complete policy basis and handling process information, and confirm that the segmentation and re-ranking configurations are effective.
