What this category of data looks like
Coal chemical industry policy and regulatory basis data is primarily sourced from official announcements of national-level departments including the National Development and Reform Commission, National Energy Administration, and Ministry of Ecology and Environment, as well as industry standards released by the China Coal Processing and Utilization Association. Data updates are triggered by the release of new policies, with no fixed cycle. Each individual document includes fields such as policy document number, issuing authority, release date, applicable scenarios, core clauses, and attachment list. Field formats include policy document numbers in the format of NDRC Energy [202X] XX, dates in YYYY-MM-DD format, and scenario descriptions without quantitative units.
What constraints do these characteristics impose on the citation sources and traceability link
The official source attribute of coal chemical policy data requires that the traceability link must match the official domain of the issuing authority, to avoid citing non-authoritative content. The lack of a fixed update cycle requires that the traceability configuration supports incremental pulling of new policies, while retaining a complete traceability chain for historical policies. Each individual document includes structured fields such as document number and release date, which requires that the traceability process must extract the document number as a unique identifier to ensure direct positioning to the original file during citation. The subdivided applicable scenario fields require that the traceability process must associate scenario tags, to avoid citing policy clauses across scenarios.
How to configure the settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | The core clause length of individual coal chemical policy documents falls within this range, avoiding truncation of key information such as document numbers and issuing authorities required for traceability |
responseData | Include original file URL and structured fields | Matches the structured characteristics of coal chemical policy documents, allowing direct extraction of document numbers as unique traceability identifiers |
detail | Enabled | Supports returning attachment content of policy documents, covering common attachment specification requirements for coal chemical policies |
| Single recall limit | Top 3 entries | The number of policy clauses for the same scenario in coal chemical industry is limited; excessive recall will interfere with answer accuracy |
| Maximum context length | 4000–6000 characters | Adapts to the splicing needs of multiple policy documents, avoiding context overflow |
Three Common Configuration Mistakes
- Phenomenon: After recalling a coal chemical policy document, only a citation prompt is returned, with no specific answer content. Cause: The value of
quoteMaxTokenis set too small, truncating the policy clause content required for the answer, leaving only traceability citation information. - Phenomenon: An input error occurs when calling the coal chemical policy Q&A plugin. Cause: The structured return format of
responseDatais not configured correctly, causing the plugin to fail to parse the field information of policy documents. - Phenomenon: Unable to match the original policy file during traceability. Cause: The
detailswitch is not enabled, and the original URL and document number fields of the policy document are not obtained, making accurate traceability impossible.
How to Verify Successful Configuration
- Upload a coal chemical policy document, initiate a relevant Q&A, and check whether the returned results include the original file URL and document number.
- Adjust the value of
quoteMaxToken, and test whether policy clauses of different lengths are fully retained or truncated. - Call the coal chemical policy Q&A plugin, confirm that there are no format errors during input, and that the returned results meet expectations.
- View logs in the FastGPT v4.17.0 backend, and confirm that the traceability process correctly extracts the structured fields of the policy document.
