Knowledge Base Retrieval for Professional Qualification Exam Applications: Manage Authorized Access and External Services

What this category's data looks like

Registration review materials for professional and technical personnel qualification examinations, including the registration form, education certificate, and work experience certificate. The registration form is filled out by the applicant, while the education certificate and work experience certificate are issued by external institutions. When entering the knowledge base for retrieval and recall, the three respectively serve the recall roles of the main record, qualification evidence, and years-of-experience evidence. Materials are updated by batch and year, and the fields include name, ID number, graduating institution, major, certificate number, start and end dates, position, employer name, signature, and receipt. A common field characteristic is that the name, quantity, and dates of the same record across different materials must be aligned item by item, and the version number and receipt status must be synchronized. After materials enter this function, the retrieval service is only responsible for recalling candidate fragments and similarity scores; the authorization entry point and visible scope are generated accordingly by subsequent nodes or manually.

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, rerank, filter, and limit trimming). The externally available entry point and authorization scope are then completed by subsequent nodes or manually.

Three common errors

• Symptom: The graduating institution name for the same record does not match between the registration form and the education certificate. Cause: The versions of the two materials are not synchronized, and field alignment verification was not performed during retrieval recall.
• Symptom: The start and end dates on the work experience certificate are inconsistent with the dates filled in on the registration form. Cause: The materials are updated at different paces, and the old version remains in the candidate fragments.
• Symptom: The registration form lacks a signature or receipt, but retrieval still returns that fragment. Cause: Similarity filtering only ranks by text relevance and does not include signature and receipt status in the trimming conditions.

How to verify the setup

This function's acceptance: test once each with synonym-rewritten questions, compare the candidates and similarity scores, then toggle usingReRank to observe the order of the first few results; record the number of candidates and the tokens of the quoted text after limit trimming.

Business test: access once with a restricted identity and check whether the visible scope matches the setting.

• In the knowledge base search test, switch among semantic, full-text, or hybrid according to searchMode, and check whether the candidates include both semantic and full-text results.
• Compare the order of the first few results before and after enabling reranking, and record the number of candidates and the similarity score, checking whether the tokens of the quoted text after limit trimming retain the key fields.
