What the Data for This Category Looks Like
Mining and mineral processing policy and regulatory basis data comes primarily from official public documents released by the Ministry of Natural Resources, the Ministry of Emergency Management, and provincial and municipal mine supervision departments. Data updates align with the release of new policies and revisions to existing policies, with no fixed schedule. Document structures include fixed fields such as policy document number, issuing authority, release date, effective clauses, and attachment list. Penalty amounts are listed in RMB yuan, and extraction limits are measured in tons. Most documents are available in PDF, Word, or web public notice formats. Document lengths vary widely, from short notification files of a few hundred words to lengthy safety regulation documents totaling tens of thousands of words.
Constraints Imposed on Citation Sources and Traceability Workflows
Official fields such as policy document numbers and issuing entities require traceability workflows to accurately match document identifiers, rather than only displaying text content. Document lengths vary greatly. Long documents require reasonable chunking to avoid information breaks. Short documents require avoiding over-splitting that causes semantic loss. Policies have timeliness and regional differences. Retrieval workflows must filter expired policies and match local supervision requirements. Attachment-style policy documents need to be traced in association with their main documents, which further increases the complexity of citation matching.
Configuration Settings
| Configuration Item | Recommended Approach | Basis for This Approach |
|---|---|---|
| Chunk Length | 800–1200 characters | Mining and mineral processing policies use clause-based structures. 800–1200 characters cover a complete single clause and avoid split breaks |
| Overlap Length | 100–150 characters | Logical connections exist between policy clauses. Overlap preserves contextual cohesion and prevents loss of cross-chunk information |
quoteMaxToken | 2000–3000 token | Policy citations need to fully display core information such as document numbers and issuing authorities. This range covers the core content of a single policy document |
| Sort Order | Reverse chronological order by release date | Mining and mineral processing policies have strong timeliness. Newly released policies take priority over older ones, aligning with current regulatory requirements |
detail | Enabled | Policy document numbers, issuing authorities and other traceability metadata must be displayed. Enabling this option returns complete document information |
responseData | Return metadata + original text snippets | Users need to verify policy sources, so both document identifiers and cited content must be displayed |
Three Common Misconfigurations
- Symptom: Markdown-formatted policy clauses cannot be rendered in context citations. Cause: Markdown tags in policy documents were not properly escaped during knowledge base preprocessing, or native text rendering was not enabled in configurations.
- Symptom: Some queries fail to match policy files in the knowledge base. Cause: Chunk length was set too large, causing policy clauses to not be fully split, or the similarity threshold was set too high, filtering eligible matching documents.
- Symptom: Traceability fields such as policy document numbers are not displayed in citation results. Cause: The
detailconfiguration item was not enabled, so only text snippets were returned without accompanying metadata information.
How to Verify Correct Configuration
- Upload a standard mining and mineral processing policy document. Run chunk preview in the knowledge base backend of FastGPT v4.17.0. Confirm that single chunk lengths fall within the set range, with no clause split breaks.
- Submit a query targeting a specific policy document number. Check if the returned results include metadata such as policy issuing authority and document number. Confirm that the
detailconfiguration is active. - Submit multiple queries related to policies of different timelines. Confirm that returned results are sorted in reverse chronological order by release date, with newly released policies displayed first.
- Check the display content of the citation module. Confirm that Markdown-formatted clauses are properly rendered, with no unescaped tag characters.
