What the data for this category looks like
Core data for this category includes animal quarantine certificates, slaughter and cutting records, ingredient marinating records, thermal processing records, cold chain temperature records, microbial test reports, and production logs related to equipment inspection and maintenance. Data sources cover animal quarantine information, supplier batch logs, production traceability systems, real-time temperature collection equipment, metal detection results, and laboratory test data. Updates follow production batch and per-shift schedules. Cold chain temperature data is collected and updated continuously. Documents include fields such as batch number, quarantine number, temperature threshold, and test indicators, with both structured logs and unstructured records.
What constraints these characteristics impose on the knowledge base retrieval and recall workflow
This category’s data involves biosecurity and production compliance requirements. Retrieval results must strictly match the corresponding batch and quarantine status, to prevent irrelevant or incorrect information from interfering with equipment inspection and maintenance decisions. Frequently updated cold chain temperature and real-time test data require the retrieval workflow to support incremental recall and timeliness filtering, to avoid calling outdated data. Diverse document formats and multi-source data require the retrieval system to support a unified recall logic for both structured and unstructured content. Equipment inspection and maintenance Q&A must be linked to production batches and quarantine information. The retrieval scope must be limited to equipment data within the corresponding production link, to avoid cross-scenario confusion.
How to configure the system
These configurations are adapted for FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | This category requires strict matching of associated information between equipment inspection and production batches, to avoid low-relevance results being included in Q&A scenarios |
limit | Top 6–8 results | Balance the amount of recalled information and response speed. Excessive results increase context processing time and reduce the smoothness of equipment maintenance Q&A |
searchMode | mixedRecall | Data for this category includes both structured logs and unstructured records. Hybrid retrieval covers equipment inspection manuals and production data in different formats |
usingReRank | Enabled | Use reranking to filter redundant results, improve the accuracy of equipment maintenance-related Q&A, and avoid irrelevant documents interfering with decision-making |
datasetSearchUsingExtensionQuery | Enabled | Optimize search terms by expanding questions, to match implicit associated information in equipment inspection manuals and production records |
collectionIds | Specify dedicated dataset ID for equipment inspection and maintenance | Limit the retrieval scope to the exclusive knowledge base of the corresponding category, to avoid interference from irrelevant quarantine or test data |
Three common configuration errors
- Phenomenon: A "no matching results" error appears during knowledge base retrieval, or retrieval results are irrelevant to equipment inspection questions. Cause:
collectionIdsare not limited to the dedicated dataset, so the retrieval scope covers irrelevant quarantine or test documents. - Phenomenon: Some PDF documents cannot be recognized, and no corresponding content is returned during retrieval. Cause: Parsing rules are not adjusted for the category’s document format, or the PDF contains encrypted content or non-standard fonts that cause parsing failure.
- Phenomenon: Retrieval response is delayed, or context processing times out. Cause: A reasonable
limitvalue is not set, and recalling too many results creates excessive system processing pressure.
How to verify correct configuration
- Upload dedicated equipment inspection records and production documents for the category, confirm that
collectionIdsonly points to this dataset, and that retrieval only returns content from the corresponding documents. - Enter equipment inspection-related questions, check that the
similarityscores of returned results fall within the preset range, and that results are highly relevant to the question. - After enabling
usingReRank, compare the sorting of retrieval results before and after enabling, and confirm that the relevance of reranked results has improved. - Test retrieval of frequently updated cold chain temperature data, confirm that the latest collection records are returned, and that no outdated data interferes with results.
