What this category's data looks like
This page addresses the international student admissions and enrollment management scenario. Materials include international student admission brochures, admission letters, and visa application forms. Admission brochures carry the program, duration of study, application requirements, and deadlines; admission letters carry the admission decision, registration date, and signature; visa application forms carry personal information, passport number, and receipt. The three types of materials often enter the knowledge base in parallel as scanned copies, electronic forms, and revised drafts, with update cadence changing with admission batches and visa policies. Field characteristics center on name spelling, passport number, program name, dates, and signature fields, and the same record may be written differently across materials. When materials enter the knowledge base retrieval function, each participates in recall as a candidate snippet source and does not directly generate basis entries.
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 pattern, merge, rerank, filter, and limit trimming). Basis entries that can be traced back to the original text are completed by subsequent nodes or manually.
| Object | Check | Verification action |
|---|---|---|
| International student admission brochure | Check whether fields, dates, and signature are consistent with the admission letter | Switch searchMode in the search test and compare semantic, full-text, and hybrid recall candidates |
| Admission letter | Check whether the program name, registration date, and signature field are synchronized with the brochure version | Compare the order of the top few items before and after enabling rerank, and record the similarity score |
| Visa application form | Check whether name spelling, passport number, and receipt match the admission letter | Adjust limit to observe changes in the number of candidates and confirm key snippets are not trimmed |
| Knowledge base retrieval service | Candidates come from multiple recall paths and have been merged, reranked, and filtered | Test once each with synonymous questions, record the number of candidates and scores, and check the effect of the usingReRank switch |
Three common errors
- Symptom: The same student's name spelling or program name does not match between the brochure and the admission letter. Cause: The two materials were entered separately, without field-level comparison and version synchronization.
- Symptom: The visa application form lacks a signature or receipt, and the admission letter date is inconsistent with the brochure deadline. Cause: The scanned materials did not verify the signature field, and date fields were not traced back to the original text.
- Symptom: The same question phrased differently cannot be recalled, and although there are many candidates, the top-ranked ones are irrelevant. Cause: The retrieval mode does not match the material form, rerank is not enabled, or similarity filtering is too strict.
How to verify the setup
Acceptance for this feature: test once each with synonymously rewritten questions, compare candidates and similarity scores, then toggle rerank to inspect the ordering of the top few items, and check the values of searchMode and limit.
Business test: ask a cross-material basis question and see whether the answer provides a traceable source.
- In the knowledge base search test, switch
searchModefor the same question, record the number of candidates and scores, and check whether the multi-path merge result includes both semantic and full-text candidates. - Compare the order of the top few items before and after enabling
usingReRank, and after adjustinglimit, check the tokens and array length of the cited text to confirm key snippets are not trimmed.
