Data Characteristics for This Category
Water industry investment research data originates from internal pipeline operation reports, real-time monitoring node data, water quality test reports, industry policy documents, and professional research reports. Update rhythms vary significantly. Real-time monitoring data such as pipeline pressure and flow updates hourly. Monthly operation reports update weekly or monthly. Industry policies and research reports update irregularly, quarterly, or annually. Document structures include structured tables (such as pipeline parameters, water quality indicators), long-text analysis reports, scattered inspection records and equipment ledgers. Some inspection records are unstructured handwritten scans that require OCR parsing before being added to the knowledge base. Fields and units have clear industry-specific attributes. For example, pipeline pressure uses MPa as the unit, water quality pollutant concentration uses mg/L as the unit, and equipment IDs are string-form unique identifiers.
Constraints for Deployment and Upgrade
The multi-type and varied update rhythm characteristics of water industry data create clear constraints for knowledge base deployment and upgrade workflows. High proportions of structured tables with nested headers require parsing modules to support complex Excel/CSV parsing, to avoid field loss or misalignment. Hourly update requirements for real-time monitoring data require configuring incremental sync triggers during deployment, to reduce resource usage and time spent on full indexing. Mixed structures of long-text reports and scattered small documents require compatibility with segment rules for different document lengths during upgrades, to avoid breaking professional term integrity. Industry-specific multi-unit fields require configuring metadata standardization mapping rules before deployment, to avoid recall bias caused by inconsistent units during retrieval.
Configuration Recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300-600 seconds | Water industry documents include long-text operation reports and Excel files with nested headers. Too short a timeout causes parsing failures |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single annual pipeline operation reports from water industry groups may exceed 1 GB. Upload limits must be relaxed |
chunkSize | 800-1200 characters | Water industry documents contain many professional terms and long sentences. Too short segment lengths break term integrity. Too long lengths reduce recall accuracy |
RECALL_TOP_K | Top 8-12 results | Water industry investment research requires associating multiple data types including pipeline data, water quality indicators, and policy documents. Too few recall results miss associated content |
ENABLE_INCREMENTAL_SYNC | Enabled | Water industry monitoring data updates hourly. Incremental sync reduces indexing resource usage and improves update efficiency |
MODEL_API_TIMEOUT | 600 seconds | Locally deployed private large models require adaptation to intranet latency and long-text parsing time when processing complex water industry queries |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing values.
Three Common Misconfigurations
- Phenomenon: A
Connection refusederror is returned when calling a locally deployed private large model. Cause: API port access permissions for the local model are not configured, and the correct intranet access address is not filled in the FastGPT model configuration page. - Phenomenon: Water quality monitoring images uploaded to the knowledge base cannot be refreshed synchronously with knowledge base updates. Cause: The automatic image index update configuration item is not enabled, or the used version does not support the incremental update function for image indexes.
- Phenomenon: A
CUDA out of memoryerror occurs when deploying a parsing service locally. Cause: ThechunkSizeparameter is not adjusted based on the average length of water industry long documents, causing the text volume loaded for a single parse to exceed the graphics card video memory capacity.
How to Verify Proper Configuration
- Upload a water industry Excel report with nested headers, verify that parsed fields are complete, with no missing or misaligned entries.
- Initiate an incremental sync task, verify that only updated monitoring data is correctly indexed, and that unchanged historical data is not reprocessed.
- Call a locally deployed private large model to initiate a water industry data query, verify that the returned results include correct content from intranet data sources.
- Simulate concurrent retrieval requests, verify that the service does not show significant delays or errors. Adjust concurrency thresholds later based on actual business needs.
