What Data for This Category Looks Like
Service subjects for this category include education bureau financial aid centers, school student affairs offices or financial aid offices, and finance departments. Data primarily comes from the National Student Financial Aid Management Information System, school student status systems, civil affairs subsistence allowance and extremely poor household data, and fiscal payment systems. Daily processed documents include family economic hardship certification forms, financial aid application forms, scholarship and grant review forms, distribution lists and public notice materials. Data updates follow a semester cycle. Fields cover core content such as financial aid qualification determination, student status status, hardship certification information, and distribution details.
What Constraints Do These Characteristics Impose on the "Knowledge Base Retrieval and Recall" Link
Multiple data sources require linked operations, so matching consistency of cross-source fields must be ensured. Retrieval must prioritize associating unique identifiers such as student ID numbers and financial aid application numbers to avoid mismatched results. The semester-based update rhythm requires the knowledge base to perform full refreshes regularly, to prevent expired in-semester review or distribution data from being recalled. Document types include structured forms and unstructured public notice texts. Recall rules for the two types must be distinguished to ensure accuracy of qualification verification. Financial aid qualification verification relies on precise matching. Recall results must strictly correspond to the specific status of the applicant, with no generalized matching of irrelevant information. The public attribute of public notice materials requires recall results to comply with compliance checks, to avoid disclosure of content that has not completed public notice procedures.
How to Configure the Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Match precise fields related to financial aid qualification, avoid irrelevant low-similarity results interfering with qualification verification |
limit | Top 8 entries | Cover all process documents for application, review and distribution within a single semester, while controlling context length |
searchMode | hybrid | Combine keyword and semantic retrieval, adapt to mixed recall needs for structured form fields and unstructured public notice texts |
usingReRank | Enabled | Re-rank initial recall results, prioritize matching student subject's student status and hardship certification related information |
datasetSearchUsingExtensionQuery | Enabled | Automatically expand question keywords, supplement business-specific fields such as student ID numbers and financial aid categories, improve accuracy |
collectionIds | Dataset IDs divided by semester | Isolate data by update cycle, prevent expired cross-semester data from being recalled |
Three Common Misconfigurations
- The issue: Imported family economic hardship certification forms show "Ready" but no matching data during retrieval. Cause: Key fields such as student ID number and family income certification number were not retained during document chunking, or the corresponding business dataset was not associated during import.
- The issue: Retrieval results include cross-semester expired distribution lists. Cause:
collectionIdswere not divided by semester, resulting in recall of old data outside the update cycle. - The issue: The number of retrieved results exceeds expectations. Cause: The
limitparameter was not set, or thesimilaritythreshold was set too low, resulting in recall of a large number of low-similarity irrelevant documents.
How to Confirm Correct Configuration
- Upload a single standard financial aid application form document, trigger retrieval and check whether the returned results include the key field information in the application form.
- Adjust the
similaritythreshold, verify whether low-similarity irrelevant documents are filtered out, and whether high-matching qualification certification documents are returned first. - Divide datasets by semester and configure
collectionIds, retrieve application data within the semester, verify that only documents from the corresponding cycle are recalled. - After enabling
usingReRank, check whether the re-ranked results prioritize matching the student subject's student status and hardship certification related information.
