What this category's data looks like
International student admissions and enrollment management involves three types of materials: admission brochures, admission letters, and visa application forms. Fields include name, passport number, major, enrollment date, signature, and receipt. The admission brochure serves as the external version source, the admission letter serves as the individual credential, and the visa application form serves as the process form. Material sources are the admissions office, academic departments, and the international student center, and the update cadence changes with the admissions season, visa policies, and enrollment status changes. When entering the knowledge base retrieval service, the brochure handles rule recall, the admission letter handles individual verification, and the visa application form handles field comparison. The version numbers, effective dates, and signature fields of the three must be traceable in the retrieval candidates, and the name, quantity, and date of the same record must be consistent across materials, with old versions retained and traceable.
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). The version ledger and change records are completed by subsequent nodes or manually.
| Object | Check | Verification action |
|---|---|---|
| Admission brochure | The name, major, enrollment date, and signature field in the brochure must be consistent with the admission letter, and the version number and effective date must be unique | In the search test, switch searchMode to semantic, full-text, and hybrid and test each once, check the number of candidates and scores, and confirm the current version is unique and old versions are traceable |
| Admission letter | The passport number, major, date, and signature receipt in the admission letter must correspond to the visa application form, and no signature or receipt may be missing | Search with synonymous questions, compare candidate snippets and similarity scores, and check whether the cited text contains the signature field and receipt field |
| Visa application form | The name, quantity, and date in the application form must be consistent with the brochure rules, and citations must be updated synchronously | Turn usingReRank on and off to compare the ranking of the top few results, record the number of items in the citation array, and separately check whether the tokens of the cited text fall within the budget |
| Version ledger | The current version is unique, old versions are traceable, and citations are synchronized | After changing one piece of content, rerun retrieval to see whether the version number and citations are updated synchronously, and whether key snippets are retained after limit trimming |
Three common errors
- Symptom: The name, quantity, and date of the same record do not match between the brochure and the admission letter. Cause: The versions are not synchronized, old versions are still recalled, and candidates are not filtered by effective date.
- Symptom: The visa application form lacks a signature or receipt, but retrieval still returns that snippet. Cause: The signature status was not marked when the material was ingested, and similarity filtering did not cover that field.
- Symptom: There are many candidates, but the ones ranked at the top are all irrelevant, and the answer lacks key paragraphs. Cause: Rerank was not enabled or
searchModedoes not match the material form, and key snippets were truncated after citation limit trimming.
How to verify the setup
Acceptance of this feature: test each synonymous rewritten question once, compare candidates and scores, then toggle rerank on and off to observe the ranking of the top few results; switch searchMode to observe differences between semantic and full-text candidates, and record the number of candidates under similarity and limit.
Business test: change one piece of content, see whether the version number and citations are updated synchronously, and confirm that the current version is unique, old versions are traceable, and the signature and receipt fields are complete.
- In the knowledge base search test, test the same question once with each synonymous question, record the number of candidates and scores, and compare the differences among the three
searchModemodes. - Run once with
usingReRankenabled and once disabled, compare the ranking of the top few results; after changing one piece of content, rerun and check whether the version number and citations are updated synchronously.
