What this category's data looks like
In the international student admissions and enrollment status management scenario, three types of materials—admissions brochures, admission letters, and visa application forms—play different roles when they enter the knowledge base retrieval and recall function: admissions brochures carry the major, program duration, fees, and application conditions; admission letters carry the admission decision, registration date, and issuer; visa application forms carry personal information, purpose of entry, and signature receipt. The material source is the finalized versions published by the school-level admissions and enrollment status departments, and the update cadence adjusts in sync with admissions batches, visa policies, and enrollment status changes. Field characteristics center on name, passport number, major name, admission batch, date, signature, and version number, and the same record needs to keep names, quantities, and dates consistent across multiple materials. After materials enter this function, they serve as the source of candidate chunks and cited content, for subsequent nodes or manual drafting of signable materials and handover records to verify that fields are complete, responsible parties are clear, and versions and dates are consistent.
Configuration and implementation checks
This step is executed by the knowledge base retrieval service (retrieval node and search test), outputting candidate chunks and similarity scores (after mode, merge, re-rank, filter, and limit trimming). The signable material drafts and handover records are then completed by subsequent nodes or manually.
| Object | Check | Verification action |
|---|---|---|
| Admissions brochure | Fields include major name, program duration, application conditions, fee description, and version date; the signature field and receipt field are complete | In the search test, test once each with synonymous questions, record the number of candidates and scores, and check whether semantic and full-text candidates appear simultaneously after switching searchMode |
| Admission letter | Fields include admission decision, registration date, issuer, and signature, and are consistent with the major name and batch date in the admissions brochure | Check the major name and date in the returned cited text, and compare the ordering of the top few items before and after enabling usingReRank |
| Visa application form | Fields include personal information, purpose of entry, signature, and receipt, and are consistent with the name, passport number, and date in the admission letter | Check whether the cited text retains the key chunks of the signature and receipt, record the number of candidates and scores, and check whether the key paragraphs remain complete after limit trimming |
| Handover record | Fields include responsible party, handover date, version number, and receipt status, and are consistent with the version of the material relied upon | Check the version number and date in the cited text, and confirm that the cited source of the handover record corresponds to the material version |
Three common errors
- Symptom: The major name or batch date for the same student does not match between the admissions brochure and the admission letter. Cause: The two records were not synchronized to the same version, and the retrieval candidates did not hit both materials at the same time.
- Symptom: The visa application form lacks a signature or receipt, yet the handover record continues to be circulated. Cause: After similarity filtering, the cited text did not retain the signature chunk, and the responsible party did not verify that the fields were complete.
- Symptom: The same question cannot be recalled when rephrased, or there are many candidates but the ones ranked at the top are all irrelevant. Cause: The retrieval mode does not match the material form, re-rank is not enabled, or the citation limit is trimmed too aggressively.
How to verify the setup
This function's acceptance: test once each with synonymously rewritten questions, compare candidates and scores, then toggle re-rank on and off to observe the ordering of the top few items; switch searchMode to compare semantic and full-text candidates, check the order before and after usingReRank, record the number of candidates and scores, and when a citation limit is involved, check the tokens of the cited text and record the array count separately.
Business test: draft one copy according to the template and complete one handover, see whether missing items are blocked, and verify that fields are complete, responsible parties are clear, and versions and dates are consistent.
- In the knowledge base search test, test once each with different phrasings of the same question, record the number of candidates and scores, and confirm that the candidates include both semantic and full-text results.
- Compare the ordering of the top few items before and after enabling re-rank, and check whether the cited text retains the key chunks of the signature, receipt, and version date.
