What the data for this category looks like
The data for gas intelligent due diligence reports primarily comes from daily inspection ledgers of gas operation enterprises, pipe network maintenance archives, upstream gas supply contracts, and safety supervision announcements from local housing and construction authorities. Daily inspection data is updated daily. Pipe network maintenance archives are updated quarterly. Gas supply contracts and supervision data are updated annually.
The document structure includes structured inspection record forms with fields such as pipeline pressure, burial depth, and coordinates of gas leakage points, as well as unstructured safety assessment reports. Field units use fixed industry standard units including MPa for pressure, cubic meters for gas consumption, and meters for burial depth.
What Constraints These Characteristics Impose on Multi-turn Dialogue and Prompt Engineering
The classification dimensions of gas due diligence data, including pipe network segments, regions, and inspection cycles, and unit rules are clearly defined. Multi-turn dialogue must first confirm the target query scope to avoid matching irrelevant pipe network historical data.
The update frequencies of different data sources vary significantly. Prompts must explicitly specify whether to use the latest inspection data or historical contract data to prevent returning outdated information.
The units of structured fields are fixed. Prompts must strictly verify the unit format of extraction results to avoid parameter matching errors.
Image content in unstructured reports must be separately associated with corresponding inspection records. Multi-turn dialogue must support embedded display of image links.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Gas due diligence reports contain multiple sections of inspection records and contract text, requiring sufficient retained context to prevent loss of critical parameters |
recallTopK | Top 6 entries | Gas data is categorized by inspection region and pipe network segment. Too many recalled entries will introduce irrelevant data, while too few will miss core due diligence items |
similarityThreshold | 0.75–0.85 | Gas parameter units and field names follow fixed formats. A threshold that is too low will match data from non-target pipe network segments, while a threshold that is too high will result in insufficient recall |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | A single gas inspection report may contain dozens of pages of images and text, leading to long parsing times |
promptTemplate | Extract region and pipe network segment parameters first based on user questions, then match corresponding data | Gas due diligence requires precise targeting of the target pipe network, and multi-turn dialogue must gradually confirm parameters |
multiTurnMaxRound | 3–4 rounds | Gas due diligence only requires confirming three core parameters: region, pipe network segment, and report type. Too many rounds will increase user interaction costs |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. Testing on independent samples is recommended before finalizing settings.
Three Common Misconfigurations
- Phenomenon: Inspection images included in returned due diligence reports fail to display properly, only showing text placeholders. Cause: The prompt does not explicitly require embedding image links from the knowledge base in responses, or image recall association parameters are not configured.
- Phenomenon: Extracted pipe network parameters such as pressure values and gas consumption have incorrect units or field mismatches. Cause: The prompt does not specify standard fields and units for the gas industry, and does not perform format verification on extraction results.
- Phenomenon: User-provided pipe network region parameters from prior interactions are not correctly retained in multi-turn dialogue, requiring repeated confirmation. Cause: Multi-turn dialogue context caching configuration is not enabled, resulting in context being cleared for each new query.
How to Verify Proper Configuration
- Initiate a query specifying a target pipe network segment and inspection date, verify that returned results only include gas data for the target region with no irrelevant entries.
- Upload a due diligence report containing inspection images, request display of relevant images, verify that correct image links are embedded in the response.
- Initiate step-by-step queries: first request the pipe network region to be queried, then add the inspection date. Verify that the system retains prior parameters and completes subsequent matching.
- Trigger parsing of a large due diligence report, verify that no timeout errors occur during parsing and that returned content is complete.
