Knowledge Base Retrieval for Technical College Program Management: Manage Authorized Access and External Services

Technical Colleges: review retrieval for authorized access. Check source versions, input mappings and the values received by downstream nodes.

What this category's data looks like

This category's data covers three types of materials: student registration records, teaching plans, and skills training records. Student registration records are updated by enrollment batch and semester, with fields including name, major, class, registration date, and signature; teaching plans are revised by major and grade, including course name, credit hours, assessment method, and approval signature; skills training records are registered by training project and cycle, including project name, equipment number, training date, and instructor signature. When these three types of materials enter the knowledge base retrieval and recall function, student registration records and teaching plans serve as the foundational materials for determining the authorization scope, while skills training records serve as the candidate content source that can be retrieved in external services. Material versions are updated in sync with semester and major adjustments; signatures and receipts are the credentials that make materials effective.

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 pattern, merge, re-rank, filter, and limit trimming). The externally accessible entry points and authorization scope are completed by subsequent nodes or manually.

ObjectCheckVerification action
Student registration recordsWhether fields, dates, and signatures are consistent with the class and major names in the teaching plansIn the knowledge base search test, switch searchMode, compare semantic and full-text recall candidates, and check the registration date and signature fields
Teaching plansWhether versions are in sync, and whether course names, credit hours, and assessment methods correspond to the skills training recordsCompare the order of the top few candidates before and after enabling usingReRank, and check the plan version number and approval signature
Skills training recordsWhether the training project name, equipment number, training date, and instructor signature are completeUse synonymous rewrites of the same question to retrieve once each, record the number of candidates and the similarity score, and check the signature and receipt fields
External entry points and authorization scopeWhether visitor identity matches the visible scope, and whether unauthorized content is invisibleAccess once with a restricted identity, check whether the returned candidates fall within the authorization scope, and record the number of citations after limit trimming

Three common errors

  • Symptom: The name or class of the same student does not match between the student registration records and the skills training records. Cause: The two materials were entered separately and were not checked against the same student ID number.
  • Symptom: The teaching plan has been revised, but retrieval still returns the old version's course names and credit hours. Cause: The version was not synced, and the old version material was not removed from the knowledge base.
  • Symptom: Skills training records lack an instructor signature or receipt but still appear in external candidates. Cause: The material effectiveness credentials were not verified, and retrieval returns results based only on text similarity.

How to verify the setup

This feature's acceptance: test once each with synonymous rewritten questions, compare candidates and similarity scores, then toggle usingReRank on and off to observe the ordering of the top few results.

Business test: access once with a restricted identity and check whether the visible scope matches the configuration.

  • In the knowledge base search test, switch searchMode, record the number of candidates and scores for semantic, full-text, and hybrid modes respectively, check the tokens of the cited text after limit trimming, and record the array length separately.
  • Check the fields, dates, and signatures of the student registration records, teaching plans, and skills training records, and confirm that the names, quantities, and dates of the same record are consistent across the three materials, with versions in sync and receipts complete.
