What This Category’s Data Looks Like
Wind power research reports primarily come from public reports of securities research institutes, industry associations, and technical white papers from complete machine manufacturers. Update frequency aligns with industry events: new reports are added after policy releases or installed capacity data disclosures. Most documents are in PDF or DOCX format, with structures including policy summaries, installed capacity statistics, complete machine parameters, project costs, market share analysis and other modules. Field units include GW (installed capacity), MW (unit power), yuan/kW (unit cost) and others. Some reports include construction cycle data for individual projects.
Constraints on Document Parsing and Chunking
The multi-source heterogeneous nature of wind power research reports requires the parsing workflow to support both PDF text extraction and table OCR recognition. Nested table structures in some older reports add to chunking difficulty. High update frequency and frequent sudden new reports require parsing to support fast batch processing, and avoid timeout interruptions. The binding between professional parameters and their units requires retaining contextual associations during chunking, to prevent separating parameters from their units after splitting. Single documents often span dozens of pages, so a reasonable segment threshold is needed to avoid splitting complete parameters for the same unit into multiple chunks, which would harm subsequent retrieval matching.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Single PDF wind power research reports often span dozens of pages. Batch uploads of large files require sufficient reserved space to avoid upload failures |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long document parsing requires processing OCR and table extraction. The default timeout period is insufficient to complete full parsing |
chunk_size | 800–1200 characters | Wind power research reports include professional parameters and contextual associations. Excessively long chunks reduce recall accuracy, while excessively short chunks damage parameter integrity |
chunk_overlap | 100–150 characters | Retain the connection between parameters and context, to avoid splitting cross-chunk professional terms |
custom_delimiter | Determined via actual testing | Excel-format wind power installed capacity statistics tables require row-by-row separation. Default delimiters cannot adapt to table row structures |
enable_table_parse | Enabled | Installed capacity data and parameter tables in wind power research reports require complete extraction, to avoid incorrect splitting of table content |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require targeted analysis. It is recommended to test on appropriate samples before finalizing settings.
Three Common Mistakes
- Symptom: Uploaded DOCX-format wind power research reports larger than 10 MB stall at parsing progress for more than 10 minutes. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted. The default timeout period is insufficient to handle table parsing and text extraction for long documents. - Symptom: Imported Excel-format wind power installed capacity statistics tables have multiple rows of data merged into a single chunk. Cause:
custom_delimiterwas not configured as a line break. The default chunking rules do not adapt to table row separation logic. - Symptom: After importing a wind power research report with precise parameter matching, identical retrieval requests fail to recall the corresponding chunk. Repeating the operation with a newly created blank knowledge base works normally. Cause:
enable_table_parsewas not enabled during the first import, resulting in incomplete extraction of parameter text within tables. Subsequent configuration corrections were not followed by re-parsing the old files.
How to Verify Proper Configuration
- Upload a single maximum-size wind power research report, check the upload progress and parsing logs to confirm no upload timeout or parsing failure errors are triggered.
- Import an Excel-format wind power installed capacity statistics table, verify that chunking results are split per single row, with no multi-row merging.
- Input a sentence from the research report that includes complete parameters and units, confirm that the corresponding chunk can be recalled, and that professional content integrity is not damaged during chunking.
- Batch upload 3 to 5 wind power research reports, check the processing speed of the parsing queue to confirm no long-term backlog occurs.
