What this category of data looks like
Policy data related to new energy development mainly comes from officially public documents of the National Energy Administration, provincial development and reform commissions, and local energy authorities. Updates align with the release schedule of new policies. Documents primarily consist of regulatory filings, with fields including document number, issuing body, effective date, clause entry, applicable scenario description, and more. The length of individual documents varies widely, covering notices hundreds of words long to special plans tens of thousands of words in length. Some files include attached data tables, and there is no unified fixed field format.
What constraints do these characteristics impose on the citation and traceability process
The wide variation in length and dispersed sources of new energy development policy documents create multiple constraints for the citation and traceability process. Long-text special plans require reasonable paragraph splitting to avoid losing context. Short notices require retaining complete document number information. Multi-level issuing bodies and effective date fields require precise matching of the issuing unit and effective time during traceability, to avoid confusing policies with the same topic but different validity periods. Some files include attached data, which requires associating attached content synchronously, increasing the complexity of association matching during traceability.
How to configure settings
The following configurations are defined for FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Basis for This Setting |
|---|---|---|
quoteMaxToken | 6000–10000 token | Adapt to the wide span of new energy policy documents, avoid truncating core clause content |
responseData | Include document number, issuing unit, effective date | Match the core traceability fields of policy documents, meet compliance traceability requirements |
detail | Enabled | Display the original text of specific clauses, facilitating verification of the accuracy of policy basis |
| Single retrieval recall limit | Top 6 entries | Cover scenarios of multi-department joint document issuance, avoid missing relevant policy basis |
| Context window length | 1500–2000 characters | Retain the front and back context logic of policy clauses, avoid taking content out of context |
Three common mistakes
- Phenomenon: When policy-related questions are asked consecutively, subsequent answers become off-topic. Cause: No suitable context window length is configured, leading to failure to retain the policy basis context from prior questions.
- Phenomenon: Incomplete clauses or forced truncation occur during citation and traceability. Cause: The
quoteMaxTokenvalue is set too low, exceeding the token length of the target policy document paragraph. - Phenomenon: Key traceability information such as policy document number or effective date is missing from traceability results. Cause: The return fields of
responseDataare not set correctly, omitting core identifiers of policy documents.
How to confirm proper configuration
- Upload a new energy policy document, trigger a question-and-answer session, then check the returned citation content to confirm it includes the preset traceability fields.
- Test question-and-answer sessions for long-text policy documents, check that the cited content does not show unprompted forced truncation, confirming the configuration adapts to document length.
- Launch multiple consecutive rounds of policy-related questions, verify that answers can associate policy basis mentioned in previous questions.
- View the display format of citation sources, confirm that the
detailswitch configuration meets display requirements.
