What this category's data looks like
This page addresses the international student admissions and student status management scenario. The source materials are international student admission brochures, admission notices, visa application forms, and student status change receipts. The admission brochure carries the program catalog, application requirements, deadlines, and document checklist; the admission notice carries the admitted program, student ID, registration date, and signature field; the visa application form carries passport information, entry date, signature, and receipt. The three types of materials are updated by semester batch: the brochure adjusts with annual policy changes, notices are issued by admission round, and visa forms change versions with embassy and consulate requirements. Field characteristics center on name spelling, program names, quantities, dates, and signature positions. The same record often shows inconsistent names, quantities, or dates across multiple materials, versions are not synchronized, and signatures or receipts are missing. When materials enter Q&A intake and missing-item follow-up, the brochure and notice serve as the baseline for field comparison, the visa application form serves as the basis for signature and receipt verification, retrieval results provide only candidate snippets and similarity scores, and intake records and completed follow-up items are handled by subsequent nodes or manually.
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, rerank, filter, and limit trimming). Intake records and completed follow-up items are then handled by subsequent nodes or manually.
| Object | Check | Verification action |
|---|---|---|
| International student admission brochure | Fields, dates, and signature: whether the program name, application deadline, and document checklist are consistent with the admission notice | In the search test, switch searchMode and compare candidate snippets and scores under semantic, full-text, and hybrid modes, checking whether the program and dates in the brochure are recalled |
| Admission notice | Fields, dates, and signature: whether the admitted program, student ID, registration date, and signature field correspond to the brochure and visa form | Run one retrieval each with synonymous rewrites of the same question, see whether notice snippets are hit stably, record the number of candidates and scores, then enable usingReRank to compare the ordering of the top few results |
| Visa application form | Fields, dates, and signature: whether passport information, entry date, signature, and receipt are complete | After retrieving visa form snippets, check the tokens of the returned cited text, record the array count separately, confirm whether the signature and receipt paragraphs are retained, and if necessary adjust similarity and limit to observe changes in candidates |
Three common errors
- Symptom: the program name or registration date for the same student does not match between the brochure and the notice. Cause: the two materials are updated in different batches, versions are not synchronized, and retrieval returns only candidate snippets without field-level comparison.
- Symptom: the visa application form lacks a signature or receipt, yet the Q&A still gives a complete answer. Cause: the missing item is not identified, retrieval hits similar snippets without triggering follow-up questions, and the intake record lacks a pending-items list.
- Symptom: the same question phrased differently fails to recall the key paragraph. Cause: the retrieval mode does not match the material form, or the key snippet is trimmed after similarity filtering and citation limit trimming.
How to verify the setup
Feature acceptance: test once each with synonymous rewritten questions, compare candidate snippets and similarity scores, then toggle rerank on and off to inspect the ordering of the top few results, and record the number of candidates and scores.
Business test: submit a question missing key information and see whether it asks a follow-up question before answering.
- In the knowledge base search test, switch
searchMode, run semantic, full-text, and hybrid separately for the same question, record the number of candidates and scores, and check whether brochure, notice, and visa form snippets appear at the same time. - Run once before and after enabling
usingReRank, compare the ordering of the top few results; check the tokens of the cited text, record the array count separately, and confirm that the signature and receipt paragraphs are not trimmed.
