Knowledge Base Retrieval for Graduate Admissions Interviews and Selection: Coordinate Operations and Application Handover

Graduate Admissions: review retrieval for operational handover. Check source versions, input mappings and the values received by downstream nodes.

What this category's data looks like

This category's data includes three types of graduate admissions re-examination and admission materials: re-examination plans, candidate score sheets, and transfer/adjustment lists. The re-examination plan contains assessment stages, score weights, time and location, and signature fields; the candidate score sheet contains candidate number, preliminary exam total score, re-examination subject scores, weighted total score, and review signature; the transfer/adjustment list contains adjustment batch, candidate number, original application unit, proposed admission major, date, and receipt. When these three types of materials enter knowledge base retrieval and recall, their roles differ: the re-examination plan provides the process and rule basis, the candidate score sheet provides individual score fields, and the transfer/adjustment list provides batch and destination fields. Materials are updated by admissions year and batch, and field names, counts, dates, and signatures are prone to differences between versions, requiring item-by-item verification at handover.

Configuration and implementation checks

This step is executed by the knowledge base retrieval service (retrieval node and search test), outputting candidate chunks and similarity scores (after mode, merge, rerank, filter, and limit trimming). The handover-ready deployment status and operation records are completed by subsequent nodes or manually. Retrieval only provides candidates and cited content; it does not generate statistical tables, business documents, or authorization results.

Re-examination planAssessment stages, score weights, time and location, signature fields, and admissions year version are consistentIn the search test, use the same question to switch searchMode to semantic, full-text, and hybrid and retrieve once each; verify whether the returned candidates cover the plan clauses, and record the number of candidates and scores
Candidate score sheetCandidate number, preliminary exam total score, re-examination subject scores, weighted total score, and review signature match in name, count, and date between the score sheet and the transfer/adjustment listRetrieve once each by candidate number and name; verify whether the score fields and signature fields in the candidate chunks are complete, and compare the top few rankings before and after enabling usingReRank
Transfer/adjustment listAdjustment batch, candidate number, proposed admission major, date, and receipt are consistent and version-synchronized across both materialsRetrieve by adjustment batch and major name; verify whether candidates include both semantic and full-text results, and record the number retained after similarity filtering
Retrieval configurationRetrieval mode, multi-route merge, rerank, similarity filtering, and citation limit trimming are documented item by item according to the handover formVerify that the values of searchMode, usingReRank, similarity, and limit match the task records, and record the citation count separately by array length

Three common errors

  • Symptom: the name or count for the same candidate number does not match between the score sheet and the transfer/adjustment list. Cause: the two material versions were not synchronized, only one was changed during update, and no item-by-item verification was done before handover.
  • Symptom: the date or signature field is missing from the re-examination plan and transfer/adjustment list, and the receipt is not attached. Cause: signatures and receipts were not fully collected during material circulation, and the handover form did not list the missing items.
  • Symptom: the same question cannot be recalled when rephrased, or there are many candidates but the top-ranked ones are irrelevant. Cause: the retrieval mode does not match the material form, rerank is not enabled, or similarity filtering and citation limit trimming are improperly set.

How to verify the setup

This feature acceptance: test once each with synonym-rewritten questions, compare candidates and scores, then toggle rerank on and off to observe the top few rankings; record the number of candidates and scores, and verify the values of searchMode, usingReRank, and similarity.

Business test: verify item by item according to the handover form and see which item record is missing; verify the fields, dates, and signatures of the re-examination plan, candidate score sheet, and transfer/adjustment list, and confirm that version, connection, and task records are consistent.

  • In the knowledge base search test, retrieve the same question separately using semantic, full-text, and hybrid modes, record the number of candidates and scores, and compare the top few order before and after enabling rerank.
  • Verify item by item according to the handover form the fields, dates, and signatures of the re-examination plan, candidate score sheet, and transfer/adjustment list, and after confirming that version, connection, and task records are consistent, hand over to operations or the next shift.
