What This Category's Data Looks Like
Wind power-related enterprise financial report data mainly comes from periodic reports disclosed by domestic and overseas stock exchanges, project operation ledgers, and publicly available industry statistical materials. The update cycle primarily follows quarterly, semi-annual, and annual schedules; some project operation data is updated monthly. Most documents are mixed structured and semi-structured PDF formats, containing fields such as wind turbine installed capacity, annual power generation, equipment utilization hours, single-unit turbine cost, and per-kilowatt-hour cost. The corresponding units are ten thousand kilowatts, ten thousand kilowatt-hours, hours, yuan per unit, and yuan per kilowatt-hour.
What Constraints Do These Characteristics Impose on Document Parsing and Chunking
The mixed structure, specialized fields, and high-frequency update characteristics of wind power financial reports create multiple constraints for parsing and chunking. First, documents that combine semi-structured content and charts require simultaneous support for table extraction and text-image association parsing, to avoid separating chart annotations from main body text. Second, specialized fields have fixed units and business attribution. Chunking must split content by business modules such as installed capacity, operation, and cost, to prevent mixing cross-domain fields. Third, batch documents with high-frequency updates require controlling per-document parsing time to avoid exceeding processing thresholds.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_PDF_ENABLE_IMAGE | Enabled | Wind power financial reports include equipment parameter charts and power generation trend charts. Chart annotation text must be extracted to supplement semantic context |
maxChunkSize | 800–1200 characters | Business information for single fields in wind power financial reports is concentrated. Excessively long chunks lead to scattered recall semantics, while excessively short chunks lose business associations |
chunkOverlap | 100–150 characters | Wind power financial reports have cross-page business logic, such as three consecutive periods of installed capacity data. Overlapping chunks ensure contextual coherence |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Annual wind power financial report PDFs have a large number of pages, including numerous tables and charts, requiring sufficient parsing time |
RECALL_TOP_N | Top 5 entries | Core business modules of wind power financial reports are concentrated. A small number of highly relevant chunks can cover query needs |
SIMILARITY_THRESHOLD | 0.75–0.85 | Wind power financial reports contain many specialized terms. A higher threshold is required to filter low-relevance general expressions |
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 specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Issue: After uploading a wind power financial report PDF, the annotation text of equipment parameter charts is not extracted, and only the main body text is retained in the knowledge base. Cause: The
PARSE_PDF_ENABLE_IMAGEconfiguration item is not enabled, causing the parsing process to ignore attached text from images embedded in the PDF. - Issue: When parsing structured tables in wind power financial reports, units from adjacent columns such as ten thousand kilowatts and yuan per unit are merged into the same paragraph, leading to confusion in field semantics. Cause: Chunking is performed only by fixed-length text splitting without splitting by business modules, and the structural association of tables is not preserved.
- Issue: After batch uploading multiple wind power financial reports, some documents fail to parse, and the console returns a
408 Request Timeoutstatus code. Cause: ThePARSE_FILE_TIMEOUT_SECONDSconfiguration is not adjusted, and the per-document parsing time exceeds the default threshold.
How to Confirm Configurations Are Correct
- Upload a single wind power financial report PDF, view the parsed chunk content, and verify that chart annotation text is included to confirm that the
PARSE_PDF_ENABLE_IMAGEconfiguration is active. - Extract any chunk content, check that specialized fields and their corresponding units are fully associated, to confirm that the chunking logic aligns with business module divisions.
- Upload multiple wind power financial reports, check the completion status of parsing tasks, to confirm that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration covers per-document parsing time. - Initiate a query targeting fields in wind power financial reports, verify that the number of recalled chunks and similarity meet expected standards, and adjust corresponding configuration items to the appropriate range.
