What Data Looks Like for This Category
The data for water treatment intelligent due diligence reports comes primarily from publicly available monitoring data from environmental monitoring stations, daily operation and maintenance logs from water utility operators, environmental impact assessment documents for construction projects, and water quality test reports. This data supports due diligence needs for water-related projects at financial institutions.
Update frequency varies by data type: daily water quality monitoring data is updated daily or weekly, while environmental impact assessment documents are static files for the full project lifecycle.
Documents include structured detection tables with fields such as monitoring location, detection item, detected value, and corresponding unit. Unstructured sections include on-site inspection records, pollution control plan descriptions, and other content, with fields tied to industry-standard environmental protection units.
Constraints Imposed on Document Parsing and Chunking
The multi-type data characteristics of water treatment due diligence reports create multiple constraints for document parsing and chunking in financial scenarios.
Structured detection tables contain multiple correlated fields. Automatic chunking may break the binding relationship between monitoring locations, detection items, and corresponding values. Row-level context must be preserved.
Unstructured content includes a large number of environmental protection technical terms and standard units. Parsing must avoid misjudging the correspondence between units and detected values.
Additionally, reports mix static environmental impact assessment documents and dynamic monitoring data. Different data update timelines must be distinguished to avoid combining expired monitoring data with long-term valid plan content during chunking.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Water treatment due diligence reports contain a large number of structured detection tables. Enabling this option preserves the row and column structure of tables, preventing misalignment of parsed data |
Chunk Length | 800–1200 characters | Technical terms and related data are closely linked in water treatment reports. This length preserves complete context for a single set of monitoring items and accompanying analysis notes |
TABLE_ROW_GROUP_SIZE | 10–15 rows | Multi-column detection tables each correspond to multiple data points for a single monitoring location. Grouping by rows prevents cross-location data confusion |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing large environmental impact assessment documents and batch monitoring reports takes significant time. This duration covers parsing needs for most scenarios |
AUTO_CHUNK_OVERLAP | 100–150 characters | Technical terms in water treatment reports require retained context overlap across chunks to avoid semantic breaks |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Issue: When a multi-column water quality detection Excel file is uploaded, automatic chunking mixes and splits rows from different monitoring locations, failing to preserve complete data for a single row. Cause: The
TABLE_ROW_GROUP_SIZEparameter is not configured, and the default chunking logic does not group rows to associate corresponding monitoring locations and detection data. - Issue: When an environmental impact assessment PDF document is uploaded, detected values and units are separated in the parsed results. For example, "COD 100" and "mg/L" appear in separate chunks. Cause: The
Chunk Lengthsetting is too small, orPARSE_TABLE_ENABLEis not enabled, causing technical terms and associated units to be split across different chunks. - Issue: When monthly monitoring reports are batch uploaded, the parsing task returns a
408 Request Timeouterror. Cause: ThePARSE_FILE_TIMEOUT_SECONDSsetting is insufficient to cover the parsing time required for batch reports.
How to Verify Correct Configuration
- Uploading a single typical water quality detection Excel file and reviewing the parsed table structure confirms that no row data is split across rows.
- Uploading a single environmental impact assessment PDF document and randomly selecting a segment of detection data confirms that detected values and their corresponding units are within the same chunk.
- Uploading a single large monitoring report and waiting for parsing to complete confirms that no timeout error is triggered.
- Searching the chunked knowledge base content verifies that complete detection data for a specified monitoring location can be accurately matched.
