What the data for this category looks like
The core data for this category comes from the national pollution discharge permit management information platform, enterprise environmental protection ledgers, online monitoring systems, and environmental statistics systems, with a quarterly update frequency. Commonly processed documents include pollution discharge permit application forms, implementation reports, self-monitoring plans, ledger records, change applications, and permit copies. Application forms contain structured fields such as industry category and permit limits. Ledgers and monitoring reports include quantitative data such as emission concentrations and monitoring times. Most documents combine structured fields with non-compliant explanatory text, and field units mostly use environmental industry standard formats such as mg/m³ and tons/year.
What constraints these characteristics impose on the knowledge base retrieval and recall link
The data for this category comes from scattered sources and involves enterprise privacy and official compliance data, so retrieval must strictly distinguish access permissions to avoid sensitive data leaks. The coexistence of multiple document types requires retrieval to adapt to both structured field matching and unstructured text semantic recall. The quarterly update frequency requires the knowledge base to perform full synchronization regularly to ensure that reviewers obtain the latest compliance requirements and enterprise data. The review link requires accurate verification of permit limits and technical specifications, and the relevance of recall results directly affects review efficiency and compliance, so low-relevance results that interfere with judgment must be avoided.
How to set up the configuration
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Requires accurate matching of permit limits and technical specification clauses, filtering low-relevance non-compliant documents |
limit | Top 8 entries | Balances reviewers' reference needs and context overload risk, covering multiple associated documents |
searchMode | Semantic search + keyword hybrid | Adapts to dual retrieval needs for structured fields such as permit limits and unstructured text such as monitoring plan explanations |
usingReRank | Enabled | Re-sorts recall results by relevance to improve the display priority of key compliance clauses |
datasetSearchUsingExtensionQuery | Enabled | Covers common term abbreviations in the pollution discharge industry, expanding the coverage of retrieval |
collectionIds | Bound to an exclusive pollution discharge permit management knowledge base collection | Distinguishes documents for different business scenarios, avoiding interference from irrelevant data from other categories |
Three Common Misconfigurations
- Retrieval results show an unauthorized access error. The cause is that the access permission for the corresponding data source is not configured, and the access permissions for enterprise environmental protection ledgers and national pollution discharge permit platform data are not opened to the current knowledge base collection.
- The number of returned retrieval results is insufficient. The cause is that the
similaritythreshold is set too high, filtering out some necessary reference documents, or thelimitparameter value is too low, failing to recall enough associated content. - Unable to jump to the original file corresponding to the retrieved fragment. The cause is that the complete path and anchor point information of the original file was not retained during chunking, or the source file association configuration of the knowledge base was not enabled.
How to Verify Correct Configuration
- Submit a typical pollution discharge permit implementation review request, and check whether the retrieval results include technical specification documents for the corresponding industry.
- Check the prompt information of the retrieval results to confirm that there is no unauthorized access error copy.
- Click any text fragment in the retrieval results to verify whether it can jump to the corresponding position of the original file.
- Enter a query containing industry term abbreviations to confirm that relevant compliance documents can be recalled.
