What the data for this category looks like
Environmental monitoring research report data mainly comes from publicly available monitoring station data from ecological environment authorities, special reports from third-party environmental monitoring institutions, and regional environmental quality monthly summary documents. Update cycles cover hourly real-time data, daily monitoring reports, and quarterly and annual comprehensive analysis documents. A single document usually includes fields such as monitoring point number, pollutant category, real-time concentration value, sampling time, and quality control qualification mark. The units for concentration indicators are mostly μg/m³ and mg/m³, while noise-related indicators use dB(A). Some documents also include monitoring instrument calibration records.
What constraints do these characteristics impose on the citation sources and traceability link
The high-frequency updates of hourly real-time data require traceability information to be precise to the sampling timestamp, rather than only marking the document release date. The multi-field document structure requires binding unique identifiers such as monitoring point numbers and instrument numbers during traceability to avoid mixing data from different points. Different pollutants correspond to different units, so the traceability link must display both the indicator name and corresponding unit to prevent deviations in numerical interpretation. The quality control qualification mark, as the basis for data validity, must be included in the traceability display content to ensure compliance of cited data.
How to set the configuration
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
Recall count | Top 8–12 entries | The core information of a single environmental monitoring research report is concentrated. Excessive recall will introduce irrelevant monitoring point data, while insufficient recall will fail to cover core indicators |
Similarity threshold | 0.72–0.85 | Monitoring indicator names have strong recognizability. A threshold that is too low will introduce retrieval results from unrelated environmental categories |
context_window | 1200–1800 characters | The core information of a single environmental monitoring document is approximately 1000 characters, reserving sufficient space to display traceability metadata |
Display Traceability Fields | Monitoring Point ID, Sampling Time, Quality Control Mark, Unit | These fields are the core identifiers for environmental monitoring data traceability, helping to quickly locate specific monitoring data |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Batch environmental monitoring documents contain multiple sets of time-series data, which take a long time to parse, so the timeout period needs to be extended |
Rerank result count | Top 3–5 entries | Users only need traceability information for core monitoring data. Excessive display will interfere with access to valid information |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules, so specific issues require specific analysis. It is recommended to test on the reader's own samples before finalizing settings.
Three common mistakes
- Phenomenon: A red error pop-up appears during retrieval result display, prompting "Traceability field missing". Cause: Required metadata fields such as monitoring point ID or sampling time are not added to the
Display Traceability Fieldsconfiguration, causing the system to fail to generate compliant traceability information. - Phenomenon: In a workflow based on question classification, only the first triggered retrieval node can display knowledge base citations, and subsequent nodes have no traceability information. Cause:
Enabled跨节点溯源上下文同步is not enabled in the workflow global configuration, causing subsequent nodes to fail to reuse the loaded dataset configuration. - Phenomenon: When configuring the
datasetidglobal variable in the knowledge base retrieval node, the variable cannot be correctly recognized. Cause: The允许引用Global Variableswitch is not enabled in the workflow's "Variable Mapping" panel, causing the retrieval node to fail to read the global dataset ID.
How to confirm the configuration is correct
- A standard environmental monitoring document is uploaded, a parsing task is run, and the parsed fields are checked to confirm they include the traceability fields specified in the configuration items.
- A query containing specific monitoring indicators is initiated, the traceability display of retrieval results is viewed, and all configured traceability fields are confirmed to be correctly displayed.
- The global variable
datasetidis configured in the workflow, this variable is called in the retrieval node, and the variable is verified to be properly read and associated with the corresponding knowledge base. - The
Similarity thresholdconfiguration is adjusted, a test query is initiated, and the relevance of retrieval results is confirmed to meet preset requirements.
