Knowledge Base Retrieval for Modern Apprenticeships and Employer-Sponsored Classes: Draft Materials and Hand Over Responsibilities

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

What this category's data looks like

In modern apprenticeship and order-class management, school-enterprise cooperation agreements, order-class training plans, and mentor apprenticeship records are the three core types of materials. School-enterprise cooperation agreements come from signing by both the school and the enterprise, and are updated with the cooperation cycle and supplementary clauses; order-class training plans are jointly drafted by the teaching and employer departments, and are adjusted with job standards and semester arrangements; mentor apprenticeship records are filled in weekly or monthly by the mentoring master, and are updated on a rolling basis with apprenticeship progress. All three types of materials carry fields, dates, and signature elements, and when they enter knowledge base retrieval and recall, each is recalled in fragment form: agreement fragments provide the cooperation term and the scope of rights and responsibilities, plan fragments provide the correspondence between courses and jobs, and apprenticeship record fragments provide process facts. During material drafting and responsibility handover, retrieval results serve only as candidate fragments and similarity scores, for subsequent nodes or humans to compare whether fields are complete, whether the responsible person is clear, and whether versions and dates are consistent.

Configuration and implementation checks

This step is executed by the knowledge base retrieval service (retrieval node and search test), outputting candidate fragments and similarity scores (after mode, merge, re-rank, filter, and upper-limit trimming). The issuable material drafts and handover records are then completed by subsequent nodes or humans.

ObjectCheckVerification action
School-enterprise cooperation agreementFields include both cooperating parties, cooperation term, rights and responsibilities clauses, signature and date; the name, quantity, and date of the same record in two materials must matchIn the knowledge base search test, switch searchMode to semantic, full-text, or hybrid, see whether candidate fragments cover the agreement term and signature fields, and record the number of candidates and scores
Order-class training planFields include training objectives, course setup, job correspondence, version number, and effective date; when versions are not synchronized, the latest effective version prevailsCompare the order of the top few items before and after enabling re-rank, and check whether usingReRank puts plan version and date fragments first; record the number of cited items by array length, and view the tokens of the cited text separately
Mentor apprenticeship recordFields include mentoring master, apprentice, apprenticeship content, signature, and receipt; records missing signature or receipt cannot directly enter handoverTest once each with synonym-rewritten questions, see whether candidates stably recall apprenticeship records; adjust similarity and limit to observe whether key fragments are still retained after filtering and trimming

Three common errors

  • Symptom: the name, quantity, and date of the same record do not match between the agreement and the plan. Cause: the two materials were drafted separately, were not checked against the same field scope, and retrieval candidates were not cross-compared.
  • Symptom: the plan version is not synchronized, and old-version fragments are still recalled. Cause: the knowledge base was not updated by effective date, similarity was close during retrieval, and re-rank did not put the latest version first.
  • Symptom: the apprenticeship record is missing signature or receipt, and is returned during handover. Cause: the drafting step checked only content and not signature fields, the handover record did not attach the receipt, and the responsible person was unclear.

How to verify the setup

This feature acceptance: test once each with synonym-rewritten questions, compare candidates and scores, then toggle re-rank to see the order of the top few items; check the changes in the number of candidates and scores under searchMode, usingReRank, similarity, and limit.

Business test: draft one copy according to the template and complete one handover, and see whether missing items are blocked.

  • In the knowledge base search test, test once each with synonym questions, record the number of candidates and scores, and compare the order of the top few items across the three searchMode modes and before and after toggling usingReRank.
  • Draft one material according to the template and complete one handover, check fields, responsible person, version, and date item by item, and block release when signature or receipt is missing.
