Knowledge Base Retrieval for Vocational College Skills Competition Organization: Maintain Document Versions and Changes

What this category's data looks like

For data versioning and change maintenance in vocational college skills competition organization, the core materials are competition regulations, registration forms, and training plans. Competition regulations contain the event name, group, date, venue, scoring criteria, and signature fields; registration forms contain the contestant's name, ID number, competition event, supervising instructor, date, and receipt; training plans contain phases, class hours, training content, responsible person, and approval signature. The three types of materials come from different sources: regulations come from documents issued by the organizer, registration forms come from submissions by each participating team, and training plans come from the school's teaching and research group. In terms of update cadence, regulations are adjusted with pre-competition notices, registration forms change with supplementary registration and qualification review, and training plans are revised on a rolling basis as phases progress. When the materials enter the knowledge base retrieval service, each serves as a source of candidate snippets: regulations provide the basis for rules and dates, registration forms provide personnel and event fields, and training plans provide training arrangement fields. The names, quantities, dates, and signature statuses of the same record across the three materials must remain consistent, old versions must be traceable, and citations must point synchronously to the current version.

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 pattern matching, merging, reranking, filtering, and upper-limit truncation). The version ledger and change records are completed by subsequent nodes or manually.

Three common errors

• Phenomenon: The name or event of the same contestant does not match between the registration form and the training plan. Cause: The two materials were revised separately, without version synchronization and field verification.
• Phenomenon: The regulation date has been updated, but the training plan still cites the old date. Cause: The old version was not marked as invalid, retrieval candidates return both old and new snippets, and citations are not synchronized.
• Phenomenon: The registration form lacks a receipt or the training plan lacks an approval signature. Cause: After the materials were submitted, no signature status check was performed, and the version ledger did not record the missing items.

How to verify the setup

Acceptance for this feature: test once each with synonymously rewritten questions, compare candidates and scores, then toggle reranking on and off to inspect the ranking of the top few items.

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

• In the search test, switch searchMode to compare the number of candidate items and scores across the semantic, full-text, and hybrid modes, and confirm that the material form matches.
• Compare the ranking of the top few items before and after enabling usingReRank, and check the citation text tokens after similarity filtering and citation upper-limit truncation, recording the array length separately.
