What this category's data looks like
This page addresses the international student admissions and enrollment management scenario. Materials include international student admissions brochures, admission letters, visa application forms, and subsequent receipts and signature pages. The brochure provides program names, application requirements, and date specifications; the admission letter carries the name, student ID, admitted program, and registration date; the visa application form records passport information, entry date, and signature. These three types of materials are updated intensively during admissions season, with versions changing as batches progress, and fields are mainly names, quantities, dates, and signatures. When materials enter knowledge base retrieval and recall, each plays a different role: the brochure and visa application form provide candidate fragments for rules and identity fields, while the admission letter provides case record fragments; together, the three support multi-source comparison of the same record during exception tracing.
Configuration and implementation checks
This step is performed by the knowledge base retrieval service (retrieval node and search test), outputting candidate fragments and similarity scores (after pattern, merge, rerank, filter, and limit trimming). The exception list and review conclusions are completed by subsequent nodes or manually.
| Object | Check | Verification action |
|---|---|---|
| International student admissions brochure | Name, quantity, date, and signature fields must be aligned item by item with the admission letter and visa application form | In the search test, use synonymous questions to retrieve brochure fields, record the number of candidates and similarity scores, and switch searchMode to compare candidate differences among semantic, full-text, and hybrid options |
| Admission letter | The name, quantity, and date of the same record in the brochure and visa application form must be consistent, and versions must be synchronized | Compare the top few rankings before and after enabling usingReRank, check whether the hit fragments contain name, student ID, and registration date, and check whether signatures or receipts are missing |
| Visa application form | Passport information, entry date, and signature must correspond to the admission letter, and the receipt must not be missing | Adjust similarity to observe candidate changes, check the tokens of the cited text and the number of array items corresponding to limit, and confirm whether key paragraphs are retained |
| Exception list and review conclusions | Each exception must be supported by the original record, and only after the reviewer signs can it be handed to the responsible person for handling | Trace back from candidate fragments to the source materials, record the number of citations and scores, and confirm that the exception description corresponds item by item with the original fields |
Three common errors
- Symptom: The name and date of the same record in the brochure and admission letter do not match. Cause: The two versions of the materials were not updated synchronously, field specifications are inconsistent, and retrieval candidates hit different versions respectively.
- Symptom: The visa application form lacks a signature or receipt, making it impossible to confirm during review. Cause: The signature page was not completed when the materials were archived, and retrieval only recalled body fragments, missing the signature field.
- Symptom: There are many candidates but the top-ranked ones are irrelevant, and the answer lacks key paragraphs. Cause: Rerank was not enabled or similarity filtering was too loose, and the recall channel does not match the material form.
How to verify the setup
Acceptance of this feature: test once each with synonym-rewritten questions, compare candidates and similarity scores, then toggle rerank on and off to see the top few rankings.
Business test: create an exception record and see whether it can be traced back to the source materials.
- In the search test, switch
searchMode, compare the number of candidates and scores for semantic, full-text, and hybrid, and confirm that after multi-route merging both types of results are included. - Adjust
similarityandlimit, record the number of citations and the tokens of the cited text, and check whether the key fragments remain complete after trimming.
