Knowledge Base Retrieval for Public Vocational Skills Level Assessment: Maintain Document Versions and Changes

Skills Certification: review retrieval for version tracking. Check source versions, input mappings and the values received by downstream nodes.

What this category's data looks like

The daily materials for social evaluation of vocational skill level certification are concentrated in three types: evaluation implementation plans, candidate registration forms, and assessor dispatch forms. The evaluation implementation plan contains the occupation direction, level, assessment method, date, and approval signature; the candidate registration form contains name, ID number, declared level, years of work, unit, and receipt; the assessor dispatch form contains the assessor's name, certificate number, dispatched session, date, and signature. These materials are updated as batches, policy interpretations, and form templates are adjusted, and the same record often circulates among multiple materials, so field names, quantities, dates, and signature statuses easily diverge. When entering knowledge base retrieval and recall, the evaluation implementation plan serves as the rule source document, while the candidate registration form and assessor dispatch form serve as the basis for item-by-item verification; together the three support ledger maintenance in which the current version is unique, old versions are traceable, and citations are synchronized.

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, rerank, filter, and limit trimming). The version ledger and change records are then completed by subsequent nodes or manually.

ObjectCheckVerification action
Evaluation implementation planFields, dates, and signatures must be consistent with the current version, and old versions must be traceableIn the search test, use synonymous questions to retrieve the plan name and approval date, record the number of candidates and scores, and check whether the returned chunks contain the current version number and signature field
Candidate registration formThe name, quantity, and date of the same candidate in the registration form and the plan roster must matchUse searchMode to switch between semantic, full-text, and hybrid, check whether candidates hit both the name and declared level, and compare date and quantity fields item by item
Assessor dispatch formDispatched session, date, signature, and receipt must be synchronized with the plan's interpretationCompare the ranking of the top few results before and after enabling usingReRank, use similarity to observe score changes, and check whether the signature and receipt fields are complete
Version ledger and change recordsThe current version is unique, old versions are traceable, and citations are synchronizedAfter changing one piece of content, re-retrieve, record the candidate array length and the limit trimming result, check the tokens budget of the cited text, and confirm that the version number and citations are updated synchronously

Three common errors

  • Symptom: The name and declared level of the same candidate do not match between the registration form and the plan roster. Cause: The two materials were updated separately, without field-level verification against the same record.
  • Symptom: The plan has been revised, but the dispatch form still cites the old date and old signature. Cause: The version was not synchronized; the old version is traceable but is not marked as not being the unique current version.
  • Symptom: Retrieval returns many candidates, but key paragraphs are missing. Cause: After similarity filtering and citation limit trimming, the tokens of the cited text were not checked, and the array length was not recorded separately.

How to verify the setup

This feature's acceptance: test once each with synonymously rewritten questions, compare the number of candidates and similarity scores, then toggle usingReRank to see changes in the ranking of the top few results, and use searchMode to switch between semantic, full-text, and hybrid to observe recall differences.

Business test: change one piece of content and see whether the version number and citations are updated synchronously.

  • In the knowledge base search test, fix the questions, record the candidate array length and the number of items after limit trimming, check the tokens of the cited text separately, and do not compare the number of items and the budget as equal.
  • Compare the name, quantity, date, and signature receipt of the evaluation implementation plan, candidate registration form, and assessor dispatch form item by item; when inconsistencies are found, first verify hits and associations, then update the knowledge base or external documents.
