What this category’s data looks like
This data draws from national public resource trading platform water sector project financing announcements, local ecological environment department special fund allocation notices, and publicly disclosed financing information from listed water enterprises. Full data for the prior natural day updates by 18:00 each day. Documents appear as structured tables or plain text entries. Each data entry includes these fields: project name, affiliated administrative region, financing amount, fund source type, implementing entity, approval date, and approval document number. All amounts use ten thousand RMB as the unit.
Constraints on citation and traceability
The data is scattered across multiple platforms, updated in full daily, and has inconsistent field names. These characteristics create three constraints for traceability. First, field names vary across sources. Some notices label financing amount as "funds in place". Configure unified field mapping rules to ensure field consistency during traceability. Second, full daily data volume is large. Use project approval document number as the unique identifier to match data and avoid cross-project confusion. Third, some local notices use nested formats. Retain the original source’s hierarchical structure to directly locate the corresponding paragraph in the original text during traceability.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall count | top 10-15 entries | Water treatment financing daily report entries are relatively short. 10-15 entries cover the day’s core financing projects and avoid redundant citations |
similarity threshold | 0.65-0.75 | Project names and approval document numbers are strong matching fields for financing daily reports. A threshold that is too low introduces irrelevant projects. A threshold that is too high fails to recall notices for the same project from different sources |
reordered return count | top 5-8 entries | Retain 3-5 most relevant sources for traceability. Reordering filters out low-correlation content |
source_id matching field | approval document number | The approval document number for water treatment financing projects is a unique identifier. It enables accurate matching of the same financing data across different sources |
file parsing format retention | retain original table/paragraph structure | Some local notices have nested formats. Retaining structure ensures the corresponding paragraph in the original text can be located during traceability |
incremental update trigger interval | 24 hours | Financing daily reports update daily. Triggering incremental updates per natural day ensures data timeliness |
The parameter values provided on this page are general recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. Testing with local samples is recommended before finalizing settings.
Three common configuration mistakes
- Phenomenon: After adjusting the
similarity thresholdorrecall countparameters, the number of recalled content remains fixed at a certain value with no obvious change. Cause: Thesource_id matching fieldis not configured as the project’s unique identifier. The system defaults to recalling based on global content similarity, and deduplication whitelist configuration is not enabled, leading to repeated filtering of similar financing entries. - Phenomenon: Returned citation content contains unrendered Markdown tags, and the format does not display as expected. Cause: When configuring
file parsing format retention, only retaining original text was selected, and front-end rendering adaptation is not enabled, so only raw syntax content is output. - Phenomenon: Water treatment financing daily report data from historical conversations cannot be directly cited. Cause: Knowledge base historical context recall configuration is not enabled, and the data source from historical conversations is not added to the current recall pool.
How to confirm configuration is correct
- Submit a test query, view the citation source list in the returned results, and check whether the project approval document number is included as a traceability identifier.
- Adjust the value of
similarity threshold, observe changes in the number of recalled entries, and confirm the configuration takes effect. - Upload a locally issued notice with nested formats, check whether the parsed text retains the original paragraph or table structure.
- Trigger an incremental update, check whether the knowledge base update log completes synchronization according to the preset cycle.
