Document Parsing and Chunking for Student Discipline and Appeals: Maintain Document Versions and Changes

What this category's data looks like

This page focuses on the student disciplinary and appeal handling scenario, outlining the version and change maintenance of three types of materials: disciplinary fact materials, disciplinary decision documents, and appeal letters. Disciplinary fact materials usually come from the college or student affairs department, recording the course of conduct, involved personnel, and dates; disciplinary decision documents are issued by the school, stating the basis clauses, types of disciplinary action, and effective dates; appeal letters are submitted by students, containing demands, supplementary facts, and signatures. After materials enter document parsing and chunking, each assumes a different role: fact materials are used to verify the original course of events, decision documents are used to confirm the current disciplinary conclusion, and appeal letters are used to track objections and subsequent changes. In terms of update cadence, disciplinary decisions may be adjusted due to review or appeal results, fact materials may be supplemented with new evidence, and appeal letters may have receipts appended. Field characteristics center on name, student ID, conduct date, disciplinary document number, signature, and receipt date; the same record must remain consistent across different materials, otherwise the version ledger cannot be unique.

Configuration and implementation checks

This step is executed by parsing and training tasks (server-side tasks), outputting data rows and index status (parsed, indexing, indexed). The "version ledger and change records" are then completed by retrieval and subsequent processing. After parsing is completed, parsing and chunking immediately persist to the database as visible data rows and bind a unique data identifier; the index transitions through the three states parsed, indexing, and indexed, and data pending indexing does not participate in recall.

Three common errors

• Symptom: the name, quantity, or date of the same disciplinary record does not match between the fact materials and the decision document. Cause: the two materials were uploaded separately, were not merged under the same data identifier, and the versions were not synchronized.
• Symptom: the disciplinary decision document has been updated, but the appeal letter still references the old version's document number and clauses. Cause: the old version is traceable but references were not synchronized, and retrieval still recalls the old data row.
• Symptom: the materials lack a signature or receipt, and the version ledger cannot confirm closure. Cause: parsing and chunking only persist visible data rows, and the signature and receipt fields were not included in the verification dimensions.

How to verify the setup

This feature's acceptance: upload one material, observe the data row status transitions and the coverage scope of the rebuild task, confirm that the three states parsed, indexing, and indexed are consistent with the interface display, and that the rebuild targets only data whose indexing has been completed.

Business test: change one piece of content, see whether the version number and references are updated in sync, and verify whether the respective identities of the file record and the data row can be distinguished.

• Open the data row to verify the status, confirm that it is in one of parsed, indexing, or indexed and consistent with the interface display, and record the splitting results of chunkSize and chunkSplitter.
• Verify the file record and the data row separately, confirm the processing mode corresponding to trainingType, and check whether the rebuild task covers only indexed data.
