What the data for this category looks like
Sources of gas industry research reports include public reports from domestic gas industry associations, annual and semi-annual performance announcements of listed gas enterprises, and segmented research reports from professional energy consulting institutions. Regular in-depth reports are released quarterly. Monthly operational data briefings are issued. Temporary special documents are generated during sudden gas supply fluctuations or pipeline network policy adjustments. Most documents are in PDF format. They contain fields such as total gas supply, pipeline network transmission mileage, terminal sales unit price, and policy compliance requirements. Common units are ten thousand cubic meters, kilometers, and yuan per cubic meter.
What constraints these characteristics impose on model access and configuration
The long-document nature of gas industry research reports requires models to reserve sufficient context window margin. This prevents loss of cross-page field association logic during chunking. Frequent regular updates and temporary ad-hoc documents require configurations that support fast incremental upload and automatic synchronization mechanisms. The mixed unit system of fields requires configuring unified unit parsing rules during model access. This avoids unit confusion during question answering. Large-volume single-upload documents require adjusting relevant parameter thresholds for file parsing and chunking. This prevents timeouts or parsing failures.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 12000–16000 tokens | Adapts to the content length of in-depth gas industry research reports, avoiding loss of cross-slice field associations |
UPLOAD_FILE_MAX_SIZE | 200 MB | Covers the volume upper limit of most single gas industry research report PDFs, preventing large document upload failures |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Adapts to the processing duration of long document parsing, avoiding timeout interruptions of the parsing process |
chunkSize | 800–1200 characters | Retains complete descriptions of core fields such as gas supply unit price and pipeline network mileage, and controls the length of single-segment context |
Recall count | Top 8 entries | Covers multi-dimensional operational, policy, and price data in gas industry research reports, avoiding omission of key information |
avatar | PNG/JPG format, HTTPS link, dimensions 64×64 to 200×200 pixels | Complies with icon loading specifications for model calls, ensuring normal interface display |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing.
Three common errors
- Phenomenon: A context overflow error triggers after uploading a long document to the knowledge base, or core data is truncated in question answering results. Cause: The
chunkSizeandmaxContextparameters are not adjusted for the long-document characteristics of gas industry research reports, and the chunking logic fails to retain cross-page field associations. - Phenomenon: Custom icons configured for the model fail to load properly, and the interface displays blank or incorrect placeholders. Cause: The icon link does not use the HTTPS protocol, or the icon format does not meet specifications, resulting in resource loading failure.
- Phenomenon: Term confusion occurs in question answering results for Chinese gas industry research reports, or units of fields such as gas supply and unit price cannot be accurately identified. Cause: The selected large language model has not been optimized for Chinese professional domains, or the context window configuration is insufficient to cover complete research report content.
How to confirm the configuration is complete
- Upload a typical gas industry research report document, and check if the parsed chunks match the preset segment length configuration.
- Submit a test question targeting core fields in the research report, and verify that the returned results include accurate field associations and unit descriptions.
- View the icon preview on the model configuration page, and confirm that the icon loads normally and meets the preset format requirements.
- Simulate batch uploading multiple different types of gas industry research reports, and check that the upload and parsing processes run without abnormal errors.
