What this category of data looks like
Data for policy and regulatory basis Q&A for iron and steel smelting comes primarily from official documents released by national industry and information technology authorities and state-owned asset supervision authorities, covering topics such as industrial capacity replacement, environmental emission standards, and smelting process specifications. It also includes internal rules of state-owned and public enterprises related to work safety, raw material procurement, and compliance management. The update cycle for this data is not fixed. Industry policies adjust based on regulatory requirements, while internal rules are updated irregularly alongside compliance reviews. Most documents follow the official red-headed document format, with structures including document numbers, issuing authorities, effective dates, clauses and sections. Fields include policy ID, applicable scenarios, penalty clauses, and execution indicators. Many execution indicators use specific units: for example, capacity is measured in tons per year, and emission indicators are measured in mg/m³.
What constraints these characteristics impose on knowledge base retrieval and recall
The hierarchical clause structure of documents requires that retrieval chunking preserves clause associations, to avoid truncating critical policy context. Specific fields and units require matching corresponding fields during retrieval, to prevent recalling policy content from mismatched scenarios. The lack of a fixed update rhythm requires the knowledge base to support on-demand synchronization and version tracking, to ensure retrieved policies are the currently valid versions. Cross-level document sources require retrieval to support filtering by issuing authority, to narrow the scope of compliance retrieval.
How to Configure
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Iron and steel policies are rigorous compliance documents. This range balances precision and recall coverage, filtering low-relevance results. |
limit | Top 10 results | Too many single-round retrieval results will exceed the context window. 10 results cover the retrieval needs for core policy basis. |
searchMode | vector+keyword | Policy text has both semantic relevance and exact field matching requirements. The hybrid mode can recall both semantically related and keyword-matched documents. |
usingReRank | Enabled | Iron and steel policies have high similarity. Reranking further filters redundant results and improves the ranking priority of core policies. |
datasetSearchUsingExtensionQuery | Enabled | There are many proprietary terms in the iron and steel industry. Extended queries supplement synonym matching, expanding the recall scope of policy terms. |
collectionIds | Specify the exclusive collection ID for iron and steel smelting policies | Limit the retrieval scope to only iron and steel smelting-related policies, avoiding interference from documents of other categories. |
Three Common Configuration Errors
- After clicking to add a new iron and steel smelting policy knowledge base folder, the interface displays a "provider not found" error. This occurs when the service provider parameters for the corresponding policy data source have not been configured in the system, or the selected service provider does not support the parsing format of red-headed documents.
- A 401 status code is returned when synchronizing the knowledge base collection via API, with a prompt indicating authentication failure. This happens when the FastGPT API key has not been added to the access whitelist of the internal policy document system, or the key permissions do not cover the policy document reading scope.
- The retrieved policy results include a large number of general environmental protection documents. This is caused by failing to limit retrieval to the iron and steel smelting exclusive policy collection via
collectionIds, resulting in mixed documents from other categories.
How to Verify Successful Configuration
- Manually upload an iron and steel smelting environmental protection policy document, run a keyword retrieval, and confirm that the returned results include the corresponding clauses of this document.
- View the FastGPT retrieval log, confirm that
searchModeis set to hybrid mode andusingReRankis active, and the number of returned results matches thelimitsetting. - Call the FastGPT API interface with a policy keyword, check whether the
similarityscore of the returned results falls within the preset 0.75–0.85 range. - Test the API synchronization function, confirm that the latest files from the internal policy document system can be pulled normally, with no authentication-related errors.
