What this category's data looks like
This page addresses the international student admissions and enrollment management scenario; the materials include international student admission brochures, admission notices, and visa application forms. The admission brochure provides the major, quota, application conditions, and deadline; the admission notice provides the admission decision, registration date, and issuer; the visa application form provides the name, passport number, study period, and signature field. These materials are updated according to admission batches and the pace of enrollment status changes, and the fields are mainly names, quantities, dates, and signatures. When entering the reranking and hybrid retrieval feature, the admission brochure, admission notice, and visa application form each participate in recall as independent candidate sources; hybrid retrieval simultaneously runs the vector and full-text paths and merges the results. After merging, the scope is large and similarity filtering cannot be applied directly, so a reranking model is usually then used to sort and filter by rerank score, providing sorted candidates and rerank scores for subsequent citation trimming and answer generation.
Configuration and implementation checks
This step is executed by the reranking model in the retrieval service, which outputs sorted candidates and rerank scores. The basis entries that can be traced back to the original text are then completed by citation trimming and answer generation. Hybrid retrieval simultaneously runs the vector and full-text paths and merges the results. After merging, the scope is large and similarity filtering cannot be applied directly, so a reranking model is usually then used to sort and filter by rerank score.
| Object | Check | Verification action |
|---|---|---|
| International student admission brochure | Fields, dates, and signatures match those in the admission notice and visa application form | Check whether the major name, quota number, and application deadline in the brochure are consistent with the admission notice, and inspect the issuer's signature field |
| Admission notice | The version is current and consistent with the study period and name in the visa application form | Check the notice version number and effective date, and compare the name, passport number, and study start and end dates on the visa application form |
| Visa application form | Signatures and receipts are complete, and the name, quantity, and date of the same record can be traced back to the original text | Check the applicant's signature, acceptance receipt, and date, and confirm that the name, quantity, and date are consistent with the same record in the admission brochure and admission notice |
| Hybrid retrieval and reranking | Both paths are enabled and merged, and reranking has been used for sorting and filtering | Check searchMode and usingReRank in the search parameters, compare the number of candidates and scores before and after reranking, and if necessary use similarity and limit to observe the recall scope |
Three common errors
- Symptom: the same student's name spelling, quota number, or date does not match between the admission brochure and the admission notice. Cause: the two materials are entered in different stages, and cross-material field comparison and traceback verification are lacking.
- Symptom: the visa application form still references the study period from an old version of the admission brochure, and the signature or receipt is missing. Cause: the version was not synchronized, and re-verification and signature confirmation were not triggered after the materials were updated.
- Symptom: there are many candidates but the top few are irrelevant, similarity filtering appears ineffective, and the results lean toward keyword hits. Cause: after hybrid retrieval merging, the scope is large and rerank score filtering was not used.
How to verify the setup
Feature acceptance: compare the order and rerank scores of the top three before and after enabling reranking, check the number of candidates and score changes, and confirm that usingReRank and searchMode have taken effect.
Business test: ask a cross-material basis question, see whether the answer provides traceable sources, and check that the cited entries come from the institution’s materials, that the version is current, and that the entries match the original text.
