What This Category of Data Looks Like
This category of data primarily comes from the food safety sampling and monitoring system, the State Administration for Market Regulation sampling results query system, laboratory LIMS, and enterprise account books. Daily documents include sampling plans, sampling slips, inspection reports, unqualified food verification and disposal reports, and risk control announcements. Data is updated on a monthly basis. Data fields cover sampling batches, sample names, inspection items, non-conforming items, disposal measures, and other related items. No custom units are used. Core documents primarily combine structured forms and unstructured reports.
Constraints Imposed on Knowledge Base Retrieval and Recall by These Characteristics
Monthly updated data requires retrieval and recall workflows to adapt to periodic data refreshes, and avoid referencing expired documents. The mixed structured and unstructured document structure requires support for multi-format content chunking and precise matching. The need for multi-source data access requires ensuring the retrieval scope covers all compliant data sources. Documents related to non-conforming product disposal have extremely high timeliness requirements. Retrieval must prioritize the latest released risk control and disposal announcements, while ensuring the field matching accuracy of inspection reports to avoid incorrect associations.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Matches the field matching accuracy required for structured documents such as inspection reports and sampling slips, and avoids recalling non-sampling-related policy documents |
limit | Top 6 results | Covers the policy basis and sampling-related documents required for a single Q&A, and avoids context overload |
searchMode | hybrid | Balances keyword matching and semantic retrieval, adapting to mixed structured and unstructured sampling documents |
usingReRank | Enabled | Reranks the top 10 retrieved results, prioritizing high-priority documents such as non-conforming product disposal reports and inspection reports |
datasetSearchUsingExtensionQuery | Enabled | Expands retrieval terms based on user questions, covering different types of documents such as sampling plans and risk announcements |
collectionIds | Bind the specified food safety sampling dataset | Limits the retrieval scope to compliant sampling-related data sources, avoiding mixing in policy documents from other categories |
Three Common Configuration Mistakes
- Issue: A query requests matching sampling policy basis that meets three requirements A, B, and C simultaneously, but the returned results only cover some conditions and fail to fully match all requirements. Cause:
datasetSearchUsingExtensionQueryis not enabled, and no semantic expansion is performed on user questions, resulting in retrieved documents not covering all relevant policy entries. - Issue: After importing WeChat official account links related to food safety supervision, corresponding documents cannot be retrieved. The interface shows import successful but no results are returned during retrieval. Cause: The imported dataset is not correctly associated with the specified sampling business collection, or the document preprocessing process is not enabled.
- Issue: Retrieval results mix non-food safety sampling policy documents that are irrelevant to the current business. Cause:
collectionIdsis not configured to limit the retrieval scope, resulting in the retrieval scope covering datasets from other categories.
How to Confirm Configurations Are Correct
- Run a test query by entering "Policy basis for unqualified food verification and disposal". Check whether the retrieval results include the latest risk control announcements and disposal reports.
- View the source tags of retrieval results to confirm that only content from the bound food safety sampling dataset is included, with no irrelevant documents.
- Run a multi-condition query by entering "Sampling policies that meet sampling specifications, inspection standards, and disposal requirements simultaneously". Check whether the returned results cover all relevant entries.
- After enabling
usingReRank, check whether the reranked results prioritize displaying high-priority documents such as inspection reports and disposal documents.
