What this category's data looks like
This category covers admission brochures, admission letters, visa application forms, and similar materials. Fields include name, passport number, major, program duration, registration date, signature, and receipt. The admission brochure carries the major and application conditions; the admission letter carries the admission decision and registration date; the visa application form carries personal identity and entry information. The name, quantities, and dates in the same record must be consistent across all three materials; the version must be unique and old versions must be traceable. The update cadence of materials is affected by admission batches, visa policies, and enrollment status changes. Each change should produce a new version number and be referenced in sync. When materials enter the knowledge base retrieval node, they serve as citation sources for subsequent field comparison, ledger writing, and report generation.
Configuration and implementation checks
This step is executed by the citation output of the knowledge base retrieval node, which outputs an array of cited content, each item containing an original text snippet and a source identifier; the length may be 0. The "version ledger and change records" are completed afterward by subsequent AI nodes, code nodes, or manual work.
| Object | Check | Verification action |
|---|---|---|
| International student admission brochure | Fields, dates, and signature must be consistent with the admission letter and visa application form | Check the major name, application deadline, signature field, and receipt requirements in the brochure; use responseData (non-streaming module results returned with detailed output enabled) to see whether the citation array points back to the original paragraphs of the brochure |
| Admission letter | Name, passport number, major, and registration date must be consistent with the visa application form | Check the name spelling, passport number, major, registration date, and signature in the admission letter; use quoteList to see whether the cited snippets correspond to the original text of the admission letter |
| Visa application form | Name, passport number, and entry date must be consistent with the admission letter | Check the name, passport number, entry date, and signature in the visa application form; use quoteMaxToken to check the citation text budget, and record the number of array items separately |
| Knowledge base retrieval node | Knowledge bases associated with the same vector model; the citation array length may be 0 | In the node, check the selected knowledge base collection and vector model; run a test with a question that has no matching materials to confirm the output is empty while the chain continues |
Three common errors
- Symptom: The major name and registration date for the same student do not match between the admission brochure and the admission letter. Cause: Versions were not synchronized, old materials are still being cited, and the current-version uniqueness principle was not followed when updating.
- Symptom: The visa application form lacks a signature or receipt, and the quantity fields in the admission letter and the application form are inconsistent. Cause: The material circulation step did not verify signatures and receipts, and fields were not compared across materials.
- Symptom: The answer has no citation superscripts, or the cited snippets do not match the original text. Cause: First check whether this round hit anything and which material was hit, then look at trimming; do not directly attribute it to length trimming.
How to verify the setup
Feature acceptance: Ask a question that has supporting original text, check whether the citation array and superscripts point back to the original text, and use responseData to view the cited content array; then ask a question with no matching materials and confirm the array is empty while the chain still runs through.
Business test: Change one piece of content and see whether the version number and citations update in sync; the number of citations is the array length, and quoteMaxToken is the citation content budget; the two are not compared for equality.
- Open the search parameter panel and check each value item by item against the knowledge base retrieval section, confirming that the knowledge bases associated are those of the same vector model.
- Run a test with a question that has no matching materials, see that the output is empty while the chain continues, and record the number of array items and the tokens of the citation text.
