What the Data for This Category Looks Like
Air governance research report data sources include publicly available monitoring datasets from ecological environment departments, air governance white papers from industry associations, and special local environmental protection survey documents. Update frequencies fall into three categories: real-time monitoring data is updated hourly, quarterly industry research reports are released quarterly, and annual special reports are released annually.
Document structures include monitoring station codes, sampling times, pollutant concentration values, governance measure details, and regional air quality ratings. Fields and units are as follows: station code (no unit), pollutant concentration value (mg/m³), governance cost (ten thousand yuan), sampling period (hourly). Single document lengths vary widely, ranging from single monitoring records to dozens of pages of special demonstration reports.
Constraints on Citation Source and Traceability Posed by These Characteristics
The multi-source heterogeneity and varying update frequencies of air governance research reports create multiple constraints for citation traceability.
Real-time monitoring data updates hourly, so traceability must be tied to hourly sampling timestamps to avoid mixing data versions across time periods. Three different document formats are used, with different identification fields across sources. Unified field mapping rules must be configured to ensure accurate matching between citations and sources.
Wide variation in document lengths requires segmented retrieval traceability anchors to be configured for different document types, avoiding deviations in traceability coverage of cited passages.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_top_k | Top 10-15 retrieved results | Air governance research reports have high data density. Too many retrieved results will cause context redundancy, while too few will fail to cover key information |
rerank_top_k | Top 5-8 retrieved results | The re-ranking step filters low-relevance retrieved results, retaining sources that closely match core air governance issues |
source_field_map | Monitoring Data: Site Code, Sampling Time; Research Report: Issuing Organization, Release Date; Special Report: Compiling Unit, Compiling Year | Different sources have different identification fields, so corresponding fields must be mapped to complete traceability identification |
citation_chunk_size | 800-1200 characters | Core demonstration paragraphs of air governance research reports are mostly around 1,000 characters. This length accurately locates cited passages |
enable_source_citation | Enabled | Citation traceability information must be output to meet compliance requirements |
max_context_tokens | 8000 tokens | Single air governance research report documents have relatively long lengths, so sufficient context space must be reserved to carry traceability information |
The parameter values given on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: The number of context entries displayed on the interface does not match the actual number of retrieved sources. For example, the interface only shows 30 entries but backend logs show 310 retrieved entries. Cause: The parameter mapping for
recall_top_kandrerank_top_kis not configured correctly. The number of entries filtered in the re-ranking step is not synchronized to the front-end display logic. - Phenomenon: Citation traceability is not associated with the corresponding data timestamp, leading to cross-time-period air governance data confusion. For example, yesterday’s monitoring data is bound to today’s research report conclusions. Cause: The mapping rule for the sampling time field is not configured in
source_field_map, so traceability only relies on the overall release time of the document and cannot match the hourly updates of real-time monitoring data. - Phenomenon: Attempting to remove citation output has no effect, or invalid citation formatting remains in the generated results. Cause: The
enable_source_citationparameter is not correctly disabled, or the preset placeholder code of the citation template is modified incorrectly.
How to Confirm Proper Configuration
- Check the parsing results after source data is uploaded, verify that the fields configured in
source_field_mapare correctly extracted and displayed. - Initiate a research report retrieval request, compare the number of retrieved entries displayed on the interface with the configured values of
recall_top_kandrerank_top_kto confirm the numbers match. - Check the citation identifiers in the generated results, confirm that the associated fields match the source identifiers configured in
source_field_map. - Adjust the
enable_source_citationparameter and initiate the request again, confirm that the citation output in the results meets the configuration requirements.
