Knowledge Base Retrieval for Modern Apprenticeships and Employer-Sponsored Classes: Find Supporting Evidence

Apprenticeships: review retrieval for evidence lookup. Compare the source records, required inputs and downstream results before handing the task over.

What this category's data looks like

This page addresses business basis queries in modern apprenticeship and order class management. Material types include school-enterprise cooperation agreements, order class training plans, and master mentorship records. School-enterprise cooperation agreements carry the cooperation entities, training positions, term, and signatures; order class training plans carry course arrangements, rotation plans, and assessment methods; master mentorship records carry mentorship dates, process content, and master signature receipts. The three material types are updated by semester or project milestone, and field characteristics concentrate in four categories: name, quantity, date, and signature. When entering knowledge base retrieval and recall, agreements and plans serve as the main material for semantic recall, mentorship records serve as a supplement for full-text recall, and image attachments participate in image description retrieval or image vector retrieval according to model capability, with multi-path results finally fused into cited content.

Configuration and implementation checks

This stage is executed by the knowledge base retrieval service (retrieval node and search test), outputting candidate chunks and similarity scores (after mode, merge, re-rank, filter, and limit truncation). Basis items that can be traced back to the original text are then completed by subsequent nodes or manually.

ObjectCheckVerification action
School-enterprise cooperation agreementFields, dates, and signatures must match the order class training plan; the name and quantity of the same record must be consistent across both materialsIn the knowledge base search test, switch searchMode, ask using the position name and term from the agreement, check whether candidate chunks carry the original date and signature location, and record the number of candidate items and scores
Order class training planThe version must be the current one, and course and rotation dates must not conflict with master mentorship recordsAsk using the course name and rotation month from the plan, turn usingReRank on and off to compare the ranking of the top few results, and check whether the returned citations point to the current version
Master mentorship recordMentorship dates, process content, and master signature receipts must be complete; entries missing a signature or receipt cannot serve as a basisAsk using the process and date from the mentorship record, adjust similarity to observe candidate increase or decrease, and check whether the cited text retains the signature column and receipt field
Knowledge base retrieval serviceCandidate chunks and similarity scores are output after mode, merge, re-rank, filter, and limit truncation; the number of citations is recorded separately by array lengthIn the search test, view the number of returned candidate items and scores, check the tokens budget of the cited text after limit truncation, and confirm that key passages have not been cut off

Three common errors

  • Symptom: the name, quantity, and date of the same mentorship record do not match between the agreement and the plan. Cause: multiple materials were entered separately, without field-level comparison and unified naming.
  • Symptom: the plan has been revised, but retrieval still recalls the old version of courses and rotation arrangements. Cause: versions were not synchronized, and old files were not taken down or marked with current status.
  • Symptom: a mentorship record lacks a master signature or receipt but is still cited as a basis. Cause: the signature column was not checked before the material was stored, and retrieval recalls only by text similarity.

How to verify the setup

This feature's acceptance: test once each with synonym-rewritten questions, compare candidates and scores, then turn re-ranking on and off to see the ranking of the top few results; switch searchMode to observe differences between semantic and full-text results, and adjust similarity and limit to record changes in the number of candidate items and scores.

Business test: ask a cross-material basis question, see whether the answer gives a traceable source, and check whether the source can be traced back to the original text location, date, and signature in the agreement, plan, or mentorship record.

  • In the knowledge base search test, retrieve once each with different phrasings of the same basis question, record the number of candidate items and scores, and confirm that cross-material entries can all be traced back to the original text.
  • Retrieve once each with re-ranking on and off, compare the ranking of the top few results, and check the tokens budget of the cited text and the array length, recording them separately.
