What the documents look like
An MCN organization manages long-term account compliance for multiple creators rather than serving a single brand campaign. The working materials include creator signing contracts, training records, violation handling forms, and account schedules. Cross-border and multilingual retrieval requires the same set of materials to be findable across Chinese, English, or other languages, and document parsing and chunking determine the basic form these materials take once they enter the knowledge base.
Creator signing contracts usually contain structured elements such as the contracting parties, the object of the arrangement, the validity period, and the scope of authorization. Training records and violation handling forms contain dates, account identifiers, and handling status. Account schedules involve dates and creator identifiers. These materials are not uniform in language, and segmentation needs to preserve the complete relationship between clauses and their constraints, avoiding the separation of subject, object, and validity scope.
Constraints at the document chunking step
Multilingual materials depend on the cross-language understanding capability of semantic retrieval in vector search, but chunking quality directly affects recall precision. If a creator signing contract splits the authorization scope and the validity period into different data chunks, retrieval may recall only one fragment. Violation handling form numbers and account identifiers suit full-text retrieval, while natural-language descriptions suit semantic retrieval, and hybrid retrieval merges the two paths through RRF. A single set of original data can correspond to multiple vector indexes, and adding multiple indexes for the same data chunk can improve recall coverage, but the index content needs to maintain a traceable relationship with the original identity and version.
Hypothetical paper exercise sample: an excerpt from an English creator signing contract reads, "Party A authorizes Party B to use the account @demo_creator for live commerce in the Southeast Asia region from 2025-03-01 to 2025-08-31. This authorization does not include sublicensing." A draft sentence to be assessed reads, "The contract's authorization scope covers the Southeast Asia region, the validity period runs to 2025-08-31, and sublicensing is included." The check compares the draft sentence against the original text on three fields: authorization scope, validity period, and sublicensing. The original text explicitly excludes sublicensing, while the draft sentence claims it is included, forming a mutually exclusive value on the same field.
Configuration and implementation checks
The table below centers on the hypothetical sample and lists officially documented settings or implementation check items relevant to this feature. The values are hypothetical starting points for this exercise, used to explain the reason for selection and the comparison method; they do not represent official defaults.
| Configuration item | Hypothetical starting point for this exercise | Reason for selection and comparison method |
|---|---|---|
| Search mode | Hybrid retrieval | Contract numbers and account identifiers need full-text retrieval; clause semantics need semantic retrieval. Compare whether the two recall paths cover the same data chunk. |
| Reference limit | Hypothetically set to 2000 tokens | The contract excerpt is short. Compare whether this value can contain the complete clause without truncating the authorization scope and validity period. |
| Minimum relevance | Hypothetically set to 0.3 | Used to observe whether low-relevance fragments are filtered after semantic retrieval or reranking. Compare against recalled content item by item. |
| Question optimization | Hypothetically enabled | In multilingual retrieval, short questions may lack a subject. Compare whether the retrieval terms are completed with the creator identifier or contract number after enabling. |
| Result reranking | Hypothetically enabled | After hybrid retrieval the candidate set is large. Compare the ranking difference between the rerank score and the vector score. |
| Chunk review | Manual inspection | Check paragraph by paragraph whether authorization scope, validity period, and sublicensing remain in the same data chunk or can be traced back to the same original data. |
Three common errors
- Treating a successful upload as an updated retrieval index. After a material change, the actual training and index status needs to be checked; the upload action itself does not indicate that the new chunk has entered the retrievable range. Check method: enter the changed contract number for retrieval and compare whether the returned content contains the new version clause. If the old version is still returned, the index has not been updated.
- Treating a semantic recall score as a permission or entity filter. The minimum relevance is a filtering threshold and does not distinguish creator accounts or contract parties. Check method: retrieve using another creator's account identifier and compare whether the returned results contain contract fragments that do not belong to that creator. If they do, retrieval has not performed entity isolation.
- Accepting "sublicensing is included" in the draft sentence directly. The original text explicitly excludes sublicensing, and the draft sentence and the original text hold mutually exclusive values on the same field. Check method: compare the draft sentence against the original text field by field. If any of the three items—authorization scope, validity period, sublicensing—is inconsistent, mark it as pending verification and do not treat the draft sentence as confirmed fact.
How to verify the setup
- Enter the contract original text and the draft sentence from the hypothetical sample, and compare whether the draft sentence matches the original text on the three fields of authorization scope, validity period, and sublicensing. Expected observation: the sublicensing field shows mutually exclusive values, and the draft sentence is marked as pending verification and does not enter a confirmed state.
- Enter the contract number or account identifier for full-text retrieval, and compare whether the returned results contain the corresponding data chunk. Expected observation: when the number or identifier hits, a fragment containing that field is returned; if nothing is returned, record it as not recalled and do not infer that the data does not exist.
- Enter the Chinese question "What is the authorized region of this contract" (English rendering) and compare whether the fragment returned by semantic retrieval contains "Southeast Asia region" from the original text. Expected observation: cross-language semantic retrieval hits that fragment; if an empty result is returned, use the explicit paper input [] to check the downstream design, record it as a miss for this attempt, and do not claim that the retrieval rule necessarily returns empty.
Retrieval or form collection of values does not constitute authorization execution. A pending review status does not demonstrate the absence of operating permission. Signing, cooperation reaching agreement, and contract effectiveness are three distinct facts. Missing evidence remains missing, and fields not stated remain unknown.
