Knowledge Base Retrieval for Vocational Training Subsidy Applications: Handle Multilingual Materials and Terminology

What this category's data looks like

This page addresses vocational training subsidy application materials, covering three types of sources: training class filing records, sign-in records, and completion assessment forms. The update cadence rolls with class sessions, and fields include institution name, class session number, personnel name, date, quantity, and signature receipt. In the multilingual materials and terminology handling scenario, class filing records carry the first occurrence of terms and translation-name anchoring, sign-in records carry item-by-item cross-referencing of personnel and dates, and completion assessment forms carry the closure of assessment conclusions and signatures. When the three types of materials enter knowledge base retrieval and recall, each participates as a candidate chunk source in semantic, full-text, or hybrid recall, and then undergoes merging, reranking, filtering, and limit truncation to form cited content, for use in the subsequent generation of the unified terminology table and the comparison draft.

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 mode, merging, reranking, filtering, and limit truncation). The unified terminology table and comparison draft are completed next by subsequent nodes or manually.

Three common errors

• Symptom: The name, quantity, and date of the same record do not match between the training class filing record and the sign-in record. Cause: The versions of the two materials were not synchronized, and the first occurrence of the term was not back-referenced to the source text.
• Symptom: The completion assessment form lacks a signature or receipt, and the terminology table and comparison draft cannot be closed. Cause: The signature field was not checked when the materials were archived, and the retrieval candidates did not cover the receipt chunk.
• Symptom: The same term cannot be recalled when phrased differently, and although there are many candidates, the ones ranked at the front are all irrelevant. Cause: The retrieval mode does not match the material form, reranking is not enabled, or similarity filtering is too strict.

How to verify the setup

This feature's acceptance: test once each with synonym-rewritten questions, compare the number of candidates and the similarity score, then toggle usingReRank on and off to observe changes in the ranking of the first few items.

Business testing: sample three terms to check whether the writing is consistent throughout, confirm that the translation name can back-reference the source text, and check and record the number of cited items (array length) and the cited text tokens separately.

• In the knowledge base search test, switch searchMode and compare the differences in candidate chunks and scores among the semantic, full-text, and hybrid modes.
• Check the number of returned cited items and the cited text tokens, record the order of the first few items once before and once after enabling usingReRank, and check whether key chunks are retained after limit truncation.
