Knowledge Base Retrieval for Technical College Program Management: Handle Questions and Collect Missing Information

Technical Colleges: review retrieval for question intake. 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 materials: student registration forms, teaching plans, and skills training records. Student registration forms contain student name, student registration number, registration date, and handler's signature; teaching plans contain course name, class hours, semester, and approval signature; skills training records contain training item, number of workstations, training date, instructor's signature, and receipt. The three types of materials are updated by semester or batch, with fixed fields and signature positions. When the materials enter the Q&A acceptance and missing-item follow-up function, student registration forms are used to verify identity and registration status, teaching plans are used to verify the basis for courses and class hours, and skills training records are used to verify training items and signature receipts. The names, quantities, and dates of the three must be consistent, versions synchronized, and signature receipts complete.

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). "Acceptance records and items to be completed" are handled by subsequent nodes or manually.

ObjectCheckVerification action
Student registration formFields include name, student registration number, registration date, and handler's signature, and are consistent with the student roster and semester in the teaching planIn the search test, switch searchMode to semantic, full-text, or hybrid, check the number of candidates and scores, and confirm that the registration date and signature fields are recalled
Teaching planCourse name, class hours, and semester match the training items and dates in the skills training records; when versions are not synchronized, the latest approved version prevailsEnable usingReRank to compare the ordering of the top few results, and check whether the course name and class hours appear completely in the candidate snippets
Skills training recordTraining item, number of workstations, training date, instructor's signature, and receipt are complete, and the name, quantity, and date of the same record are consistent across the two materialsAdjust limit to observe changes in the number of candidates, record the referenced text tokens and array count, and confirm that the signature and receipt fields have not been trimmed or lost

Three common errors

  • Symptom: The name or student registration number of the same student does not match between the student registration form and the teaching plan. Cause: The two materials were not checked against the same field standard when entered, or the versions were not synchronized.
  • Symptom: The number of training items in the skills training record does not match the class hours in the teaching plan. Cause: Training records are counted by workstation, while teaching plans are counted by class hour, and the counting basis has not been unified.
  • Symptom: The student registration form lacks the handler's signature, or the skills training record lacks a receipt. Cause: The signature confirmation was not completed during the material circulation step, and the signature and receipt fields were not checked during archiving.

How to verify the setup

This function's acceptance: test once each with synonymous rewritten questions, compare candidates and scores, then toggle rerank on and off to inspect the ordering of the top few results; switch searchMode and usingReRank, and record the number of candidates, scores, and referenced text tokens under limit, with the array count recorded separately.

Business test: ask a question missing key information and see whether it first asks a follow-up question before answering.

  • In the knowledge base search test, retrieve the same question once with different phrasings, compare candidate snippets and similarity scores, and confirm that recall is stable.
  • Enable and disable rerank, compare the order of the top few candidates; adjust the reference limit, check the referenced text tokens and array count, and confirm that the key signature and date fields are still present.
