What the Data for This Category Looks Like
Gas utility financial report data mainly comes from periodic announcements of listed gas enterprises both domestic and overseas, monthly operation statistics from industry associations, and gas supply data from local housing and urban-rural development departments. Update cycles are divided into regular and irregular: quarterly reports are released 1 to 2 months after the end of the quarter, annual reports are disclosed by the end of April of the following year, and monthly gas sales and pipeline operation data are updated dynamically alongside industry statistics. Most documents are in PDF format, with structures including business discussion sections, core operating data tables, financial statement notes and other chapters. Fields include gas sales volume (unit: 10,000 cubic meters), operating revenue (unit: 10,000 yuan), natural gas pipeline length (unit: kilometers), gas storage capacity (unit: 10,000 cubic meters) and other specialized indicators.
What Constraints These Characteristics Impose on the Knowledge Base Retrieval and Recall Link
Multi-source data sources require retrieval pipelines to support mixed recall across announcements and industry statistical data, to avoid missing cross-channel gas operating indicators. Content with different update frequencies needs differentiated incremental update trigger rules, to ensure the timeliness of syncing monthly operation data and quarterly financial reports. Long document structures require retaining chapter boundaries during parsing, to avoid mixing content from unrelated sections into retrieval context. Differences in specialized fields and units require retrieval models to align with gas industry-specific terminology and measurement rules, reducing the probability of irrelevant results being recalled.
Configuration Settings
| Configuration Item | Recommended Value | Basis for This Setting |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1500 MB | Covers the single-file size of most annual reports and supporting announcements from listed gas companies |
maxContext | 800-1200 characters | Fits the length of core operating paragraphs in gas financial reports, avoids introducing irrelevant section content |
Number of retrieved entries | 4-6 entries | Balances coverage of key data points in gas financial reports and context redundancy |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Reserves sufficient processing time for parsing large-volume gas financial reports |
Similarity threshold | 0.75-0.85 | Filters out irrelevant results with too low matching degree to gas-specific terminology |
Number of re-ranked returned entries | 3-4 entries | Focuses on the most core operating and financial indicators in gas financial reports |
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 Misconfigurations
- An error "File size exceeds limit" pops up when importing gas financial report PDFs. The cause is failing to adjust the
UPLOAD_FILE_MAX_SIZEparameter to a value adapted to the single-file volume of gas financial reports. - No matching results are returned when querying current monthly gas sales data via chat. The cause is failing to configure a knowledge base incremental update task triggered monthly, and failing to sync the latest industry operation statistics data.
- When calling the privately deployed retrieval API, the number of returned results is fixed at 6 and cannot be adjusted. The cause is failing to modify the
maxRetrieveparameter value in the configuration file.
How to Confirm Proper Configuration
- Upload a single annual report PDF from a listed gas company, check the upload progress and parsing status, confirm that the
UPLOAD_FILE_MAX_SIZEparameter is adapted to the current file volume. - Initiate a query containing specialized terms such as "gas sales volume" and "pipeline length", check the matching degree of returned results, confirm that the similarity threshold setting meets business requirements.
- Call the retrieval API, verify that the number of returned results matches the expected configuration, confirm that the
maxRetrieveparameter has been modified correctly. - View the knowledge base update log, confirm that the latest gas monthly operation data has been synced successfully according to the set update frequency.
