What the data for this category looks like
The data related to environmental monitoring mainly comes from automatic monitoring station data publicly released by ecological environment authorities, pollution discharge monitoring logs uploaded by enterprises themselves, and compliance reports issued by third-party testing institutions. Automatic monitoring data is updated every 15 minutes to once per hour, while third-party test reports are updated within 1 to 3 working days after testing is completed. Most documents are structured CSV/JSON formats or PDF test reports with metadata. Fields include monitoring point code, pollutant name, measured concentration, emission standard limit, monitoring time, sampling point latitude and longitude, with units including μg/m³, mg/L, dB(A), etc.
What constraints these characteristics impose on the "citation source and traceability" link
High data update frequency and scattered sources mean the traceability link must accurately match monitoring data from the corresponding time interval, otherwise invalid cross-time citations will occur. There are many structured fields but varying formats; some PDF test reports require field extraction first, otherwise the specific monitoring point and concentration value being cited cannot be located. Data from different sources has permission differences: monitoring data uploaded by enterprises themselves must be associated with corresponding enterprise main body information, and data ownership must be verified during traceability. In addition, monitoring data cited in financial report analysis must match the corresponding regulatory standards. During traceability, the standard document number and implementation time must also be associated, which requires traceability to be bound with multi-dimensional metadata; using only text fragments does not meet the requirements.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 3-5 entries | Environmental monitoring data has short single-item content and high repetition rate of data from the same monitoring point. Too many recalled entries will cause citation redundancy, while too few will fail to cover key monitoring periods |
Similarity threshold | 0.65-0.75 | Field matching for monitoring data requires precision. A threshold that is too low will introduce monitoring data from irrelevant points, while a threshold that is too high will fail to recall valid data from the same point across different time periods |
Chunk size | 800-1200 characters | Environmental monitoring financial report analysis requires linking monitoring data with enterprise environmental protection investment and compliance status. A segment that is too long will lose field association information, while a segment that is too short will fail to fully include complete monitoring cycle data for a single point |
Citation limit | 2000-3000 tokens | The monitoring data involved in a single financial report analysis covers many monitoring points, and the total token requirement is higher than that of general question answering. A limit that is too low will truncate key compliance comparison data |
Metadata Binding Switch | Enabled | Environmental monitoring data relies on metadata such as monitoring points, standards, and time for traceability. When enabled, non-text metadata can be displayed synchronously during citation, improving traceability credibility |
Deduplication Strategy | Deduplicate by monitoring point + monitoring time | Monitoring data from the same point and same time period may be uploaded repeatedly across multiple documents. Deduplicating by these two fields avoids repeated citation of the same data |
The parameter values given on this page are conventional recommendations used to determine the starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common mistakes
- Phenomenon: Unable to recall monitoring data for a specified point when citing from the knowledge base, and the interface shows empty recall results. Cause: The
Similarity thresholdis set too high, exceeding the semantic matching limit between monitoring data and financial report text, resulting in valid data being filtered out. - Phenomenon: Some uploaded monitoring reports show training exceptions, with the log returning the
PARSE_FILE_FAILEDerror code. Cause: Third-party test reports in PDF format have encryption or non-standard typesetting, resulting in field extraction failure, and the file enters the knowledge base without being parsed. - Phenomenon: Multiple duplicate data entries from the same monitoring point but different time periods appear in citation results, without automatic deduplication. Cause: The deduplication strategy based on monitoring point + monitoring time is not configured, and only the default text hash deduplication is used, which cannot identify data from the same point at different times.
How to confirm the configuration is correct
- Upload a single standard-format monitoring data CSV file, trigger a knowledge base recall test, and check whether the number of recall results matches the set value of
Recall count. - Adjust the
Similarity thresholdto 0.6, enter a financial report query statement containing a specified monitoring point, and verify that monitoring data for the corresponding point can be recalled. - Upload two monitoring data files with identical content but different times, check whether automatic deduplication occurs when the knowledge base cites the data, and confirm that the deduplication strategy takes effect.
- View the citation source display area, confirm whether metadata fields such as monitoring point and monitoring time are displayed synchronously, and verify the configuration effect of the
Metadata Binding Switch.
