What the data for this category looks like
Wind power marketing-related documents are primarily used for customer acquisition and investment financing of wind power projects by financial institutions. Sources include wind power project feasibility study reports, unit equipment parameter manuals, regional wind resource assessment materials, customer success case white papers, compliance approval documents, and more. Update cycles adjust with project progress, equipment iterations, and marketing cycles, with no fixed schedule. Document formats include multi-page PDFs, Word documents with embedded engineering calculation formulas, compliance files with digital signatures, and large numbers of structured tables. Fields and units cover engineering-related parameters such as power (kilowatt kW, megawatt MW), hub height (meter m), swept area (square meter ㎡), power generation (kilowatt-hour kWh), wind speed (meter per second m/s), and others.
Constraints Imposed by These Characteristics on Document Parsing and Chunking
The characteristics of wind power marketing documents impose multiple constraints on the parsing and chunking process. First, large numbers of structured parameter tables require the parsing engine to accurately identify table boundaries, avoid incorrect splitting of cross-page tables, and retain the corresponding relationship between original fields and units. Second, compliance files with digital signatures must support encrypted signature formats. Standard parsing engines cannot read valid content from such files. Third, documents containing engineering calculation formulas must retain the semantic structure of the formulas. Plain text conversion will cause logic loss. Fourth, individual documents range from single-page marketing materials to dozens of pages of feasibility study reports. Adaptive adjustment of chunking thresholds is required to avoid over-splitting short documents or exceeding context window limits for long documents.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_PDF_SIGN_SUPPORT | true | Wind power marketing documents often include compliance files with digital signatures. Signature-compatible parsing mode must be enabled, compatible with FastGPT V4.9.1 and above |
chunk_size | 800–1200 characters | Wind power documents include long engineering descriptions and structured parameters. This range balances context coherence and chunk granularity |
PARSE_TABLE_EXTRACT_MODE | structured_table | Wind power marketing documents include large numbers of structured tables such as unit parameters and project budgets. Row and column structure of tables must be retained, and plain text conversion is not used |
UPLOAD_FILE_MAX_SIZE | 500 MB | Individual wind power feasibility study reports may include multiple pages of drawings and parameter attachments. Large file upload requirements must be accommodated |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Parsing large-capacity wind power documents requires a longer processing cycle to avoid parsing failure due to timeout |
enable_formula_recognition | true | Wind power documents include engineering formulas such as power generation calculation and load calculation. Formula semantics must be retained to ensure accurate subsequent retrieval |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: An error is returned when parsing wind power documents using the Doc2x tool, and the error message is truncated to
Only support .txt, .m. Cause: The uploaded file format is not supported by the current parsing engine, or the file extension does not match the actual content. - Phenomenon: After uploading a digitally signed wind power project PDF, the parsing result contains no valid text content. Cause: The compatible parsing mode for signed PDFs is not enabled. Standard parsing engines cannot read document content after encrypted signatures.
- Phenomenon: A permission error or page unavailable prompt appears after clicking the document reading link generated via the API. Cause: The temporary link generated during parsing is not configured with correct access validity, or the link becomes invalid due to an interruption during the file parsing process.
How to Verify Correct Configuration
- Upload a digitally signed wind power compliance PDF, and check whether the parsing result includes complete text and parameter content.
- Upload a wind power document containing structured parameter tables, and check whether the parsing result retains the row and column structure of the table and the original field units.
- Adjust the
chunk_sizeparameter, and compare parsing results under different chunk lengths to confirm that the chunk granularity adapts to the content length of the current document. - Upload a large-capacity wind power feasibility study report, check whether the parsing process times out, and confirm that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration meets the document processing requirements.
