What this category of data looks like
This category of data covers documents including pollution discharge permit application forms, implementation reports, self-monitoring plans, ledger records, change applications, and permit copies. Data sources include the National Pollution Discharge Permit Management Information Platform, corporate environmental protection ledgers, online monitoring systems, and environmental statistics systems. The update frequency is quarterly. Data fields include permitted emission limits, emission boundaries, monitoring requirements, ledger reporting specifications, and other items. These fields vary by industry category and permit item, with no unified fixed format.
Constraints Imposed on Multi-turn Dialogue and Prompt Engineering
Data sources are scattered and cover multiple types of business documents. Multi-turn dialogue must gradually clarify the specific document type and permit item that the user is consulting about, to avoid generating inaccurate responses due to vague information. The quarterly update feature requires prompts to clearly mark the timeliness range of the data, to prevent referencing expired content. The field logic of different documents differs, so multi-turn dialogue needs to distinguish scenarios to guide users to supplement necessary information. For example, distinguish the different inquiry logic between implementation report review and change application consultations. At the same time, errors in this field can lead to compliance risks. Prompts need to include compliance verification guidance to ensure responses meet relevant requirements for pollution discharge permit management.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Preset three exclusive variables: {permit item type}, {document type}, {enterprise industry category} | Used to bind the specific pollution discharge permit scenario of the user's consultation during multi-turn dialogue, avoid context confusion, and accurately recall corresponding business data |
messages | Retain the first 10 valid dialogue contexts | Consultations related to pollution discharge permits have strong contextual relevance. Retaining sufficient rounds ensures coherent dialogue logic, while avoiding excessive length that causes resource usage issues |
| Single search limit | Top 6 results | Associated information in pollution discharge permit documents is relatively concentrated. Too many recalled results will interfere with the large language model's judgment of professional content |
| Chunk length | 1000–1500 characters | Professional content in pollution discharge permit documents has moderate length. This chunk range ensures that a single chunk contains complete permitted emission limit or reporting requirement information |
| Maximum context window | 8000–12000 tokens | Pollution discharge permit documents contain many professional terms and fixed formats. A sufficient context window ensures the large language model can fully reference relevant data |
| Question optimization | Calibrated based on actual testing | Questions related to pollution discharge permit consultations often include industry-specific terms. Optimized questions can improve the accuracy of knowledge base recall |
Three Common Mistakes
- Phenomenon: The dialogue response result does not reference the user-uploaded pollution discharge permit ledger data, and only calls general knowledge base content. Cause: The uploaded file is not bound to the
variablesvariable, causing the large language model to fail to recognize the association relationship of the uploaded data. - Phenomenon: Dialogue times out, returning a 504 status code. Cause: Too many documents are recalled in a single search, and the context window is set too large, causing the large language model processing to time out.
- Phenomenon: The response contains expired permitted emission limit content. Cause: The prompt does not clearly mark the quarterly update frequency of the data, causing the large language model to reference unsynchronized old data.
How to Verify Proper Configuration
- Initiate a multi-turn dialogue involving specific pollution discharge permit items, check whether the first 10 valid dialogue contexts are retained.
- Upload a pollution discharge permit implementation report, initiate a statistical summary request, check whether the result references content from the uploaded file.
- Initiate a consultation related to "latest permitted emission limits", check whether the response clearly marks the data update frequency.
- Test consultations for different document types, check whether the
variablesvariable correctly binds the corresponding scenario.
