What the documents look like
Third-party overseas warehouses can serve multiple sales channels, and the seller allocates stock across them. A single replenishment batch may therefore appear in several warehouse entry appointments and last-mile delivery orders, and the parties, objects and quantity scope in each document require separate checking. The working materials in this category are replenishment plans, warehouse entry appointments, inventory age reports and last-mile delivery orders. They arrive from overseas warehouse WMS, ERP sales forecasts, freight forwarder systems and carrier bills. Weekly and daily updates mean parsing and chunking must preserve version clues so that a later check can point back to the source text.
For contract and transaction material comparison, this structure matters at the chunking step. The same replenishment batch can be described in one appointment and referenced in a delivery order, and the two documents do not carry the same commitments.
Constraints at the document chunking step
Chunking follows the structure of each material. A condition, its explanation and the content it constrains stay in the same segment, so that a retrieved segment can be read without reassembling separated fragments.
Original data and retrieval indexes are distinct. In the documented storage structure, one data group can map to several vectors, and the indexes field in dataset.datas records the corresponding vector IDs as an array. A single group of original data can therefore correspond to multiple indexes.
Retrieval locates material content. It does not perform authorization checks. Semantic recall and the minimum relevance threshold do not act as permission filters or entity isolation, and a retrieval result is not an approval or an execution basis. Libraries built on different vector models cannot be associated with each other; identifiers are checked first and non-matching libraries are excluded.
Hypothetical paper exercise sample: the warehouse entry appointment text supplied for checking reads, "Overseas warehouse A confirms receipt of seller B's replenishment batch C, with a scheduled warehouse entry date of 10 March 2025 and a quantity of 200 cartons. This appointment is used only for inbound arrangement and does not constitute a commitment to last-mile delivery timing." The draft sentence to be assessed reads, "Overseas warehouse A has committed to complete last-mile delivery on 10 March 2025." The draft sentence shares the same party as the source text, but its object changes from warehouse entry appointment to last-mile delivery. The source text states no delivery commitment, so the draft sentence is unsupported.
Configuration and implementation checks
| Configuration item | Setting | Relation to this page's sample |
|---|---|---|
| Search mode | Hybrid retrieval | The sample contains identifier C and natural language description, requiring semantic and full-text recall together |
| Reference limit | Hypothetical trial starting value of 800 tokens for this exercise | The sample source text is short; this value makes it easier to observe whether the reference is complete, compared against the actual sample length |
| Minimum relevance | Hypothetical trial starting value of 0.3 for this exercise | Used to filter low-relevance fragments, compared against the sample retrieval scores |
| Question optimization | Enabled | The draft sentence contains a reference that needs completion before retrieval |
| Result reranking | Enabled according to settings | Secondary ordering when candidates are numerous, compared against the rerank score |
| Chunking basis | Segmentation by material structure | Keeps appointment conditions and quantity scope in the same segment |
Three common errors
- Treating a retrieval hit as authorization confirmation. In the sample, the appointment text describes only an inbound arrangement, and retrieving that segment does not mean last-mile delivery was committed. The check inputs the draft sentence, compares whether the source text contains a delivery commitment field, and observes whether the hit segment concerns inbound arrangement only.
- Treating a pending review status as missing authorization. In the sample, the appointment is under review, which does not demonstrate that the seller lacks operating permission. The check inputs the status field, compares whether the source text states a permission restriction, and observes whether any permission-related wording appears.
- Treating a quotation validity period as a supply period. The sample does not involve a quotation. If a validity period appears in a material, its constrained object is compared, and the observation is whether it is misread as a supply period.
How to verify the setup
- Input the sample draft sentence "Overseas warehouse A has committed to complete last-mile delivery on 10 March 2025", compare whether the source text states a delivery commitment, and observe whether the retrieval result returns only warehouse entry appointment content. The check condition is met when the returned content contains no delivery commitment.
- Input identifier C from the sample appointment text, compare whether full-text retrieval hits that segment, and observe whether the returned segment contains the quantity of 200 cartons and the date 10 March 2025. The check condition is met when both are present.
- Input the empty reference sample
[], compare whether the downstream design handles it as an empty result, and observe whether undefined behavior appears. The check condition is met when the downstream explicitly accepts an empty result. All of the above are paper checks and were not actually executed.
