What the data for this category looks like
Financial report data for gas public utility enterprises comes primarily from publicly disclosed periodic reports, monthly operation announcements, and industry monitoring data. Update cycles include annual, semi-annual, monthly, and ad-hoc emergency matters. Document structures typically include these fields: gas sales volume, operating revenue, pipeline network operation and maintenance costs, upstream procurement volume, number of end users, and total pipeline length. Corresponding units are cubic meters, CNY, CNY, cubic meters, households, and kilometers. Some ad-hoc announcements include short text content such as price adjustment notices and pipeline network maintenance plans. Single-document lengths vary significantly.
Constraints on vector models and indexing
Multi-unit numeric fields require vector models to support numeric feature encoding, to avoid vector distance bias across different numeric types that reduces recall accuracy. Monthly high-frequency operation data requires indexes to support incremental updates, to avoid resource consumption and excessive delays from full reconstruction. Ad-hoc announcement timeliness requires indexes to support recall sorted by release time, to prioritize returning the latest content. Documents of varying lengths require chunking strategies tailored to the differences between long-text annual reports and short-text announcements, to balance context completeness and computational efficiency.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Gas financial reports include long-text operation descriptions and short numeric segments. This range balances context completeness and vector recall accuracy |
chunk_overlap | 100–150 characters | Numeric fields in financial reports often span multiple chunks. Overlap preserves associated field information |
INDEX_INCREMENTAL_UPDATE | Enabled | Gas financial reports are updated monthly at high frequency. Incremental updates avoid excessive delays from full reconstruction |
SIMILARITY_THRESHOLD | 0.75–0.85 | Numeric vectors with different units must be distinguished. This threshold balances recall comprehensiveness and relevance |
RECALL_TOP_K | Top 8–12 results | Financial report analysis requires coverage of multi-dimensional business data. This recall volume balances comprehensiveness and computational efficiency |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large annual financial report documents takes significant time. This duration covers the complete parsing process |
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 individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- A single specified gas financial report file remains in the "indexing" state for an extended period with no progress updates. The cause is failure to configure the
INDEX_INCREMENTAL_UPDATEparameter, combined with excessive delays from full indexing of large annual reports and lack of a chunking timeout threshold. - A 504 Gateway Timeout error or a "60-second timeout" prompt appears when switching knowledge base indexes. The cause is failure to adjust the
PARSE_FILE_TIMEOUT_SECONDSparameter. The default duration is insufficient for parsing large gas financial report documents. - After uploading a small gas operation data file, it remains displayed as "rebuilding index" for an extended period. The cause is failure to enable incremental indexing mode. The system attempts a full rebuild of all associated knowledge bases, leading to excessive resource usage.
How to Confirm Correct Configuration
- Upload a single large annual financial report document, check whether the parsing progress bar completes within a reasonable time, to confirm that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration matches the document size. - Upload multiple different types of gas financial report files (annual reports, monthly announcements), check the index completion status, to confirm that the
INDEX_INCREMENTAL_UPDATEparameter is active. - Initiate a financial report analysis query, check whether the recall results include multi-dimensional gas business data, to confirm that the
RECALL_TOP_KandSIMILARITY_THRESHOLDconfigurations meet analysis requirements. - Upload a short document such as an ad-hoc price adjustment announcement, check whether the recall results are sorted to prioritize the latest content, to confirm that the index's time filtering rules are configured correctly.
