What Data for This Category Looks Like
Data for this category comes from design drawings, material quality certificates, welding equipment parameters, filler metal inventory, non-destructive testing systems, and personnel qualification ledgers. Daily documents include welding procedure qualifications, welding procedure specifications, filler metal issue records, welder qualification records, weld inspection reports, and repair orders. Data updates follow the rhythm of each weld, each batch of materials, or each shift of operations. A single document typically contains clear process parameters, qualification information, and test result fields, with no unified fixed chapter format. Some documents are updated in real time alongside production progress.
Constraints These Characteristics Impose on Knowledge Base Retrieval and Recall
Dispersed data sources and high update frequencies require retrieval and recall to cover real-time data synchronized across multiple systems, to avoid matching outdated filler metal qualifications or process parameters. Documents have no unified chapter structure, so precise matching of scattered fields must be supported, rather than relying solely on fixed title positioning. Single pieces of data are strongly bound to information such as welds and batches, so retrieval must match business-related fields simultaneously to avoid welding schemes that do not meet qualification requirements. Bid documents require strict rigor, so retrieved results must strictly correspond to compliance requirements, and key constraint items must not be omitted.
How to Configure
This configuration is based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Process parameters and qualification information for welded structural components require precise matching. This interval filters low-relevance results to avoid using unqualified welder qualifications or outdated filler metal parameters |
limit | Top 8 entries | A single bid document needs to cover multi-dimensional information. 8 results balance the comprehensiveness of process, qualification, and inspection requirements while controlling context length |
searchMode | embedding | Semantically related process logic must be matched to adapt to professional expression differences in welding processes, avoiding ambiguity caused by keyword-only matching |
usingReRank | Enabled | There are many welding technical terms. Reranking corrects deviations in semantic matching to ensure that key process parameters and qualification information are retrieved first |
datasetSearchUsingExtensionQuery | Enabled | Bid scenarios require supplementary associated compliance requirements, and extended queries cover implicit constraints of procedure qualifications |
collectionIds | Welded structural component-specific collections divided by business line | Isolate documents from other categories to avoid matching irrelevant data from mechanical processing, narrowing the retrieval scope |
Three Common Mistakes
- Phenomenon: When calling the create file collection interface, the metadata field does not take effect, and the welder qualification batch information associated with the document cannot be retrieved. Cause: The metadata parameter was not passed correctly, or the parameter format does not meet system requirements, resulting in metadata not being embedded into the knowledge base vector database.
- Phenomenon: The RAG retrieval result does not include the chapter title of the weld inspection report, making it impossible to locate specific inspection items. Cause: The chunking configuration does not retain chapter title association information, or the retrieval mode does not enable title-associated matching.
- Phenomenon: The retrieval result only matches the main content of the chunk and does not associate auxiliary data, resulting in the inability to match both filler metal issue records and corresponding filler metal qualifications. Cause: The extended query function is not enabled, and auxiliary fields are not included in the retrieval matching scope.
How to Verify Correct Configuration
- Upload a welding procedure specification document, perform a retrieval test, and check whether the returned results include matching process parameters and qualification requirements.
- View the metadata fields of the knowledge base collection to confirm that the associated information of the uploaded welder qualification records and filler metal issue records has been correctly stored.
- Adjust the similarity threshold, verify whether the relevance of the returned results meets business requirements, and confirm that the threshold interval is suitable for the professional matching logic of welded structural components.
- Call the retrieval interface, check whether the returned results include chapter title information, and confirm that the chunking configuration has retained document structure associations.
