What this category's data looks like
District and county teaching research activity and lesson observation/evaluation materials include three types: teaching research activity notices, lesson observation records, and lesson evaluation minutes. Notices contain activity time, location, subject, participating schools, and signed receipts; lesson observation records contain the instructor, class, topic, observation dimensions, and signature; lesson evaluation minutes contain evaluation points, improvement suggestions, date, and signature. During deployment, operations, and application handover, these materials serve as knowledge base import sources and respectively play the roles of activity basis, classroom evidence, and evaluation conclusions. The update cadence is weekly or by activity batch. It is common for the same record to have inconsistent names, quantities, or dates across different materials, for versions not to be synchronized, and for signatures or receipts to be missing. After the materials enter the knowledge base retrieval and recall function, candidate chunks and similarity scores are first formed, and then subsequent nodes or manual work organize them into a handover-ready deployment status and operation record.
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, merge, rerank, filter, and limit trimming). The handover-ready deployment status and operation record are then completed by subsequent nodes or manual work.
| Object | Check | Verification action |
|---|---|---|
| Teaching research activity notice | Fields, dates, and signatures: activity time, location, subject, participating schools, and receipt signature are complete | In the search test, search by notice keywords, check the number of candidates and scores, and confirm that date and signature fields can be recalled |
| Lesson observation record | Fields, dates, and signatures: instructor, class, topic, observation dimensions, and signature are complete | Switch searchMode to semantic, full-text, or hybrid, and compare whether candidates cover the key fields of lesson observation records |
| Lesson evaluation minutes | Fields, dates, and signatures: evaluation points, improvement suggestions, date, and signature are complete | Compare the ranking of the first few items before and after enabling usingReRank, and confirm that lesson evaluation point chunks are not trimmed away |
| Retrieval parameters | Number of candidates and scores: key chunks are still retained after similarity filtering and citation limit trimming | Record the number of candidates, separately check the cited text tokens, and inspect the trimming effect of similarity and limit |
Three common errors
- Symptom: the name and date of the same lesson observation record do not match between the notice and the minutes. Cause: the two materials are maintained separately, and field alignment and version synchronization were not done before import.
- Symptom: the lesson evaluation minutes lack a signature or receipt, and the corresponding record cannot be found when checking the handover form. Cause: the material collection step was not closed-loop, and the signature page was not archived together with the main text.
- Symptom: there are many candidates, but the ones ranked first are all irrelevant, and the answer lacks key paragraphs. Cause: the retrieval mode does not match the material form, rerank was not enabled, or similarity filtering is too loose.
How to verify the setup
This function's acceptance: test once each with synonym-rewritten questions, compare candidates and scores, then toggle rerank on and off to inspect the ranking of the first few items; at the same time, record the number of candidates, separately check the cited text tokens, and do not compare the number of array items as equal to the citation budget.
Business test: check item by item against the handover form once, and see which record is missing, including the fields, dates, and signatures of notices, lesson observation records, and lesson evaluation minutes, as well as version and connection status.
- In the knowledge base search test, switch
searchModeto semantic, full-text, or hybrid, compare the number of candidates and scores, and confirm that it matches the material form. - Compare the order of the first few items before and after enabling
usingReRank, and check whether the cited text retains key chunks aftersimilarityandlimittrimming.
