What the Data for This Category Looks Like
Gas industry research reports mainly come from national energy industry associations, provincial gas regulatory authorities, third-party energy consulting institutions, and public announcements of listed gas companies. Update cycles are divided into regular and ad-hoc updates. Regular reports are released monthly, quarterly, and annually. Ad-hoc reports cover sudden events such as gas source price adjustments, pipeline network maintenance, and policy implementation. Document structures include modules such as upstream gas supply data, midstream pipeline transmission and distribution parameters, downstream residential and commercial gas consumption scale, industry policy documents, and corporate business analysis. Fields include gas transmission volume, gas source price, gasification rate, project construction progress, and more. Some reports include regional gas consumption statistics, with units including cubic meters, yuan per cubic meter, and others.
What Constraints Do These Characteristics Impose on Multi-turn Dialogue and Prompt Engineering
Gas industry research reports contain dense technical terms such as LNG, CNG, and pipeline transmission loss rate. Multi-turn dialogue must strictly maintain term consistency to prevent large models from confusing concepts across different energy categories. Data updates occur frequently, and ad-hoc reports account for a large share of total content. Prompts must limit recall to documents from the last 60 days to avoid outputting outdated supply and demand data. Statistical dimensions vary across different reports. For example, the statistical scope of gas consumption scale may include or exclude industrial users. Multi-turn dialogue must actively guide users to clarify statistical dimensions to avoid conflicting comparison results. Some research reports include long sections of calculation models. The context window must adapt to the associated logic of long fragments to prevent fragmentation of professional analysis.
How to Set Configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
recallTopK | Top 8–12 entries | A single gas industry research report contains multi-dimensional data, so a sufficient number of relevant segments must be recalled to cover supply and demand, policy, corporate, and other modules |
similarityThreshold | 0.72–0.78 | Gas industry research reports have dense technical terms. A threshold that is too low will introduce irrelevant documents about electricity and coal, while a threshold that is too high may miss content with detailed statistical dimensions |
chunkSize | 1000–1200 characters | Gas industry research reports include long sections of supply and demand calculation models. Too long a segment will lose context association, while too short a segment will fragment professional logic |
systemPrompt | Customized based on "Answer only using content from recalled gas industry research reports, clearly indicate the report type and update time of the data source, and actively explain differences in statistical dimensions" | There are large differences in statistical dimensions across gas industry research reports, so the scope of answers and information transparency must be strictly constrained |
maxContext | 8000–10000 characters | Multi-turn dialogue must retain user follow-up questions about terms and dimension clarifications to avoid information loss caused by context overflow |
UPLOAD_FILE_MAX_SIZE | 20 MB | The file size of a single gas industry research report PDF is usually large, so the maximum document upload limit must be adapted |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Errors
- Phenomenon: Calling the large model inference interface returns 400 Bad Request, and the interface displays template parsing failure. Cause: The prompt template does not adapt to the exclusive variable placeholders for gas industry research reports, resulting in syntax errors during template rendering.
- Phenomenon: Subsequent responses in multi-turn dialogue use inconsistent statistical dimensions with historical inquiries, leading to duplicate or conflicting values. Cause: No context reuse rules are added to the system prompt, so the large model does not inherit the statistical dimension constraints clarified in historical conversations.
- Phenomenon: Uploading a single gas industry research report PDF that exceeds the default limit triggers an upload failure error from the interface. Cause: The
UPLOAD_FILE_MAX_SIZEparameter is not adjusted, and the default limit cannot cover the file size of a single gas industry research report.
How to Confirm Proper Configuration
- A gas industry research report PDF is uploaded, the retrieval function is triggered, and returned recalled segments are checked to confirm they only include gas-related supply and demand, pipeline network, and policy content, with no irrelevant documents from other energy categories.
- A multi-turn dialogue is initiated: first the query "What is the domestic commercial and industrial gas consumption scale in 2024" is submitted, followed by the follow-up query "What is the data when calculated using the residential statistical dimension". Responses are checked to confirm they distinguish the two statistical dimensions and retain constraints from the historical conversation.
- A 20 MB gas industry research report PDF is tested for upload, to confirm the interface does not return an upload failure error.
- A complete multi-turn dialogue is initiated, and the final response is checked to confirm it indicates the report type and update time of the data source, with no fabricated content.
