What the Data for This Category Looks Like
Solid waste treatment financing daily report data is sourced from public project approval documents released by local ecological environment authorities, financing announcements from solid waste treatment enterprises, and regular submission materials from industry associations. Update cycles are typically weekly or monthly. Each document includes multiple independent financing project entries. Most documents use table or structured text formats. Core fields include:
- Project name
- Solid waste treatment category (such as construction waste, kitchen waste)
- Financing amount
- Financing subject
- Investor
- Project location
- Approval document number
Amount units are mostly ten thousand yuan, and volume units are mostly tons.
Constraints Imposed by These Characteristics on Document Parsing and Chunking
Multiple independent project entries require chunking to preserve complete information for a single project, and avoid splitting across multiple projects. Structured table formats require the parsing step to retain correspondence between fields, to prevent column data misalignment after parsing. The high-frequency weekly or monthly update cycle means individual documents have a large number of entries. Chunking logic must adapt to dense entry content. The presence of solid waste treatment-specific terminology requires the parsing step to prioritize identifying professional classification fields, to avoid incorrect splitting of terminology.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Single project information in solid waste treatment financing daily reports is mostly 500-1000 characters long. This range ensures a single chunk contains complete project information and avoids cross-project splitting |
segment_overlap_rate | 10%–15% | Structured table content has strong field associations. Moderate overlap ensures complete cross-chunk field context and improves retrieval accuracy |
PARSE_TABLE_STRATEGY | retain column associations | The correspondence between table fields in daily reports directly affects information availability. This configuration prevents column data misalignment after parsing |
UPLOAD_FILE_MAX_SIZE | 500 MB | The total size of a single monthly financing daily report file usually does not exceed 200 MB. A reasonable upper limit is set to avoid large file upload failures |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing multi-entry documents takes longer. This duration covers the parsing needs of daily report files of conventional size |
minimum_text_segment_length | 200 characters | Filters out meaningless short entries and avoids invalid chunks occupying index resources |
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. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfiguration Issues
- Symptom: After upgrading the platform version, an error "Cannot redefine property: toString" occurs when uploading solid waste treatment financing daily report CSV files. Cause: The built-in table parsing method in the new version conflicts with a custom script method with the same name, and no namespace isolation is implemented.
- Symptom: The number of chunks after parsing a single daily report document exceeds 3000, resulting in truncated results or index failure during retrieval. Cause: No chunk upper limit parameter is configured, causing the number of chunks per document to exceed the system default threshold.
- Symptom: Cross-project field misalignment appears in parsed chunks, such as the financing amount of project A corresponding to the project location of project B. Cause: The
PARSE_TABLE_STRATEGY"retain column associations" configuration is not enabled. Table content is split directly by rows during parsing, and column correspondence is lost.
How to Verify Correct Configuration
- Upload a single solid waste treatment financing daily report document of typical size, view the parsed chunk list, and confirm each chunk contains only complete information for a single financing project.
- Navigate to the knowledge base configuration page, and verify that the value of
PARSE_TABLE_STRATEGYmatches the preset configuration. - Upload multiple daily report documents of different sizes, and confirm that the upload progress bar completes normally with no timeout errors.
- Search for solid waste treatment-specific terminology in the document, and confirm that the retrieved chunks do not have field misalignment.
