What this category's data looks like
International student admissions and enrollment management involves three types of materials: international student admission brochures, admission letters, and visa application forms. Admission brochures carry the major, program duration, application conditions, and deadline; admission letters carry the admission decision, registration date, and signature field; visa application forms carry personal identity, passport information, signature, and receipt. Materials are updated by admissions season, and fields include name, nationality, passport number, major name, date, signature, and receipt. When entering the knowledge base retrieval and recall function, admission brochures serve as candidates for policy basis, admission letters serve as candidates for admission status, and visa application forms serve as candidates for identity and signature verification; the three are returned in the same retrieval request as snippets and scores, for subsequent nodes or manual comparison of fields, dates, and signatures.
Configuration and implementation checks
This step is executed by the knowledge base retrieval service (retrieval node and search test), outputting candidate snippets and similarity scores (after mode, merge, re-rank, filter, and limit trimming). The handover-ready deployment status and operation records are completed by subsequent nodes or manually.
| Object | Check | Verification action |
|---|---|---|
| International student admission brochure | The major name, program duration, and application deadline are consistent across the three materials, and the signature field is complete | In the search test, switch searchMode, run one retrieval each with synonymous questions, record the number of candidates and the similarity score, and check whether the brochure snippet contains the major and deadline |
| Admission letter | The admission decision, registration date, and receipt match the dates on the visa application form | Turn usingReRank on and off and run one retrieval each, compare the order of the top few results, record the number of candidates after limit trimming, and check whether the admission letter snippet contains the registration date and receipt |
| Visa application form | The name, passport number, and nationality are consistent with the fields in the admission brochure and admission letter, and the signature and receipt are not missing | Run retrieval with synonymously rewritten questions, record the number of candidates and the similarity score, check whether the application form snippet contains the passport number and signature field, and separately record the number of items in the citation array |
| Deployment status and operation records | The version, connection, and task records are consistent, and missing items can be located | Check item by item once against the handover list, record missing items, check the tokens budget of the cited text, and record the number of array items separately |
Three common errors
- Symptom: The major name or registration date for the same student does not match between the admission brochure and the admission letter. Cause: The two materials' versions are not synchronized, the retrieval candidates come from different versions, and they are not merged and checked against the same record.
- Symptom: The visa application form is missing a signature or receipt, but retrieval still returns snippets. Cause: Similarity filtering only matches by text, and the signature and receipt fields are not treated as independent candidate verification items.
- Symptom: The same question phrased differently cannot be recalled, or there are many candidates but the top-ranked ones are all irrelevant. Cause: The retrieval mode does not match the material form, re-rank is not enabled, and key passages are trimmed after similarity filtering and citation limit trimming.
How to verify the setup
This function's acceptance: test once each with synonymously rewritten questions, compare candidates and similarity scores, then turn usingReRank on and off to see the order of the top few results, record the number of candidates and the citation array length, and check the tokens budget of the cited text.
Business test: check item by item once against the handover list, see which item's record is missing, and check whether the version, connection, and task records are consistent.
