What the Data for This Category Looks Like
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. Updates occur quarterly. Daily processed documents include pollution discharge permit application forms, implementation reports, self-monitoring plans, ledger records, change applications, and permit copies. These cover the full workflow for pollution discharge units, from initial permit application through post-permit supervision. The data includes structured fields such as permit limit values and emission boundaries, plus unstructured content like technical specification descriptions and ledger filling requirements. Some implementation reports contain complex multi-dimensional table data, with individual documents totaling thousands of characters.
Constraints Imposed on Knowledge Base Retrieval and Recall
The quarterly update frequency requires the knowledge base to run full synchronization regularly, to prevent inaccurate inquiry and reply caused by expired data. Mixed data from multiple sources requires the retrieval system to support matching both structured fields and unstructured text. The presence of complex table documents requires chunking rules adapted to table structures, to avoid content truncation or recognition errors. The need for precise matching of core content such as permit limit values and technical specifications requires the retrieval and recall process to strictly limit interference from low-relevance results, while ensuring high-relevance content is displayed first. Daily service inquiry questions often include industry abbreviations or specific terminology, so query expansion support is needed to cover more relevant documents.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Requires precise matching of core content such as permit limit values and technical specifications, to avoid low-relevance results interfering with service inquiry and reply |
limit | Top 8 results | Pollution discharge permit-related documents have long content. Too many recalled results will exceed the context window limit, reducing answer accuracy |
searchMode | vector+keyword hybrid mode | Balances structured field matching and unstructured text semantic matching, covering different types of service inquiry questions |
usingReRank | Enabled | Performs secondary sorting on recalled results, to prioritize displaying pollution discharge permit management content most relevant to the inquiry question |
datasetSearchUsingExtensionQuery | Enabled | Supports expanding inquiry questions to cover variants such as industry abbreviations and specific terminology, improving recall coverage |
collectionIds | Bound to the exclusive knowledge base collection for pollution discharge permit management | Limits the retrieval scope, avoids interference from irrelevant data, and ensures returned results are directly related to pollution discharge permit management business |
Three Common Misconfigurations
- Stuck operations after entering the agent editing page: The page loads fully, but no editing buttons can be clicked. The console reports an error indicating abnormal dataset parameters. The cause is that the
collectionIdsparameter is not correctly configured with the exclusive pollution discharge permit knowledge base collection, or the bound collection has too much data, exceeding the system loading threshold. - Knowledge base search test score exceeds normal range: Search results show similarity scores of 4000+, which falls outside the normal range. The cause is that the
similaritythreshold is not configured, or non-standard similarity calculation logic is used, resulting in unnormalized scores. - Complex tables fail to import correctly into the knowledge base: Uploaded implementation report table content appears as scattered text or missing key data in the knowledge base. The cause is that table chunking adaptation mode is not enabled, or chunking rules are not optimized for table structures, leading to incorrect truncation of table content.
How to Verify Successful Configuration
- Confirm the
collectionIdsparameter is bound to the exclusive pollution discharge permit management knowledge base collection, to limit the retrieval scope to target data. - Test retrieval with typical service inquiry questions such as "pollution discharge permit limit values" and "self-monitoring requirements", to verify returned results include correct document content and field information.
- Check the similarity scores of search results, confirm they fall within the reasonable 0-1 range, to validate the
similaritythreshold configuration is active. - After enabling
usingReRank, confirm sorted results prioritize displaying technical specification or permit requirement content most relevant to the inquiry question.
