Knowledge Base Retrieval for Teacher Qualification Exams and Certification: Coordinate Operations and Application Handover

What this category's data looks like

Teacher qualification exam and certification materials include written and interview registration forms, Mandarin proficiency certificates, medical examination forms, ideological and moral character appraisal forms, etc. Their sources are exam institutions, language commissions, hospitals, and certification units. The update cadence changes with batches and certification seasons, and fields include name, ID number, subject, score, grade, date, and signature. When materials enter knowledge base retrieval and recall, each plays a different role: the registration form provides the subjects applied for and test area information, the Mandarin proficiency certificate provides the grade and certificate number, the medical examination form provides the medical examination conclusion and date, and the appraisal form provides the unit's opinion and seal. During deployment, operations, and application handover, these materials must be checked item by item against the handover sheet for fields, dates, and signatures to ensure that version, connection, and task records are consistent, avoiding mismatches in names, quantities, and dates for the same record across different materials.

Configuration and implementation checks

This step is performed by the knowledge base retrieval service (retrieval node and search test), outputting candidate snippets and similarity scores (after mode, merge, rerank, filter, and upper-limit trimming). The handover-ready deployment status and operation records are completed by subsequent nodes or manually.

Three common errors

• Symptom: The name or date of the same record does not match between the registration form and the medical examination form. Cause: Material sources are not synchronized, and fields and signatures were not checked item by item against the handover sheet.
• Symptom: The grade on the Mandarin proficiency certificate is inconsistent with the record in another material. Cause: The version was not synchronized, the old certificate was not updated with the certification batch, and receipt confirmation is missing.
• Symptom: The handover sheet lacks a signature or receipt, and the task records are incomplete. Cause: The deployment status was not verified for consistency among version, connection, and task records, and the shift was handed over directly.

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 inspect the ranking of the top few items; switch searchMode, adjust similarity and usingReRank, record the number of candidates and scores, and record the number of cited items separately by array length.

Business test: check once item by item against the handover sheet to see which record is missing; check the fields, dates, and signatures of the written and interview registration form, Mandarin proficiency certificate, and medical examination form, and confirm that version, connection, and task records are consistent.

• In the knowledge base search test, switch searchMode and compare the candidate results and scores of the three options: semantic, full-text, and hybrid.
• Compare the ranking of the top few items before and after enabling usingReRank, adjust similarity to observe candidate changes, and record the number of candidates and scores.
