Knowledge Base Retrieval for Self-Funded Study Abroad Application Services: Track Progress and Check Statistics

What this category's data looks like

The materials for self-funded study abroad application services include study abroad service contracts, school application forms, personal statements, and progress records updated weekly. The contract provides the signing entity, service items, and dates; the application form provides the institution, major, round, and signature field; the personal statement provides the version, word count, and submission receipt. When these materials enter the knowledge base retrieval and recall function, each plays a different role: the contract and application form are used to verify the name, quantity, date, and signature of the same record, while the personal statement is used to verify whether the version is synchronized and whether the receipt is missing. The update cadence is weekly, and the field characteristics are concentrated in the record number, material name, date, quantity, signature status, and receipt status. The progress table and the statistical scope description must be able to match the record count and the statistical count; the scope is written in the table header, and exceptions are marked separately.

Configuration and implementation checks

This step is performed 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 "progress table and statistical scope description" is then completed by subsequent nodes or manually.

Three common errors

• Symptom: The name, quantity, and date of the same record in the contract and application form do not match. Cause: The two materials are entered separately and are not verified against a unified scope.
• Symptom: The personal statement version is not synchronized, and the progress table still records the old version. Cause: The update cadence is inconsistent, and the receipt has not been backfilled.
• Symptom: The application form lacks a signature or receipt, but the statistics still count it as completed. Cause: Signature and receipt status are not included in the scope, and exceptions are not listed separately.

How to verify the setup

This function's acceptance: test once each with synonym-rewritten questions, compare the candidates and scores, then toggle rerank on and off to check the ranking of the first few items, and record the number of candidate items and the score.

Business test: use one week of records to verify the total, and check whether the scope and exceptions are clearly stated.

• In the search test, switch searchMode and compare the candidate chunks and scores of semantic, full-text, and hybrid.
• Compare the order of the first few items before and after enabling usingReRank, and verify the cited text tokens under similarity and limit; record the array item count separately.
