What This Type of Data Looks Like
Wind power financing daily reports primarily originate from wind power project loan certificates, bank credit ledgers, grid connection announcements from local energy bureaus, and weekly financing progress reports from project parties. Documents are updated daily. Structured tables form the core content of documents, with a small amount of accompanying text instructions. Some attachments include scanned loan receipt images. Core fields include wind power project installed capacity (unit: MW), financing amount (unit: ten thousand yuan), lending bank, fund arrival date, repayment term, and guarantee method. Some documents also include project approval numbers and grid connection approval document numbers.
Constraints on the Document Parsing and Chunking Process
Wind power financing daily reports center on structured tables. The parsing process must fully retain table row and column structures, and avoid splitting field association information that spans multiple columns or rows. Attached scanned loan certificates require the parsing process to support text extraction via OCR. The daily update characteristic of data sources requires chunking logic to match the information integrity of a single project per daily report, and avoid splitting associated fields such as installed capacity and financing amount of the same wind power project into different content chunks. Some fields have clear physical units. Chunking must retain the binding relationship between units and corresponding values to prevent information separation.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_ENABLE_OCR | Enabled | Documents include scanned loan certificates, and text content such as loan amount and fund arrival date in images must be extracted |
CHUNK_SIZE | 800–1000 characters | Wind power financing daily reports have tightly associated fields. A single chunk must cover the core financing information of a single project to avoid splitting key associated fields |
CHUNK_OVERLAP | 100–150 characters | Field association information across chunks must be retained to avoid loss of contextual association between adjacent chunks |
PARSE_TABLE_MODE | Retain complete table structure | Structured tables are the core data carrier. Splitting tables will lose the binding relationship between fields and units |
UPLOAD_FILE_MAX_SIZE | 20 MB | Single wind power financing daily report documents are usually small in size. This setting covers conventional batch upload requirements |
PARSE_FILE_TIMEOUT_SECONDS | 60 seconds | The parsing process for a single daily report includes OCR and table structuring. This duration covers conventional parsing time |
The parameter values provided on this page are general recommendations used as a starting point 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 Misconfigurations
- Symptom: Parsed content chunks do not include text content from scanned loan certificates. Cause: The
PARSE_ENABLE_OCRconfiguration item is not enabled, so key information embedded in images cannot be extracted. - Symptom: Chunking results split the numerical value and unit MW of wind power installed capacity into different content chunks. Cause: The
CHUNK_SIZEconfiguration uses tokens as the unit, which does not match the field unit binding characteristic of wind power financing daily reports, leading to information separation. - Symptom: When uploading multiple daily reports in batch, some documents return a
413 Request Entity Too Largeerror. Cause: TheUPLOAD_FILE_MAX_SIZEconfiguration item is not adjusted, and the default upload limit is exceeded, causing parsing to interrupt.
How to Verify Configuration Correctness
- A test daily report including a scanned loan certificate is uploaded. Check whether the parsed result contains text content from the image to confirm the configuration is active.
- Review chunked content chunks, and verify that numerical values and units of fields such as wind power installed capacity and financing amount are contained within the same chunk to confirm the chunking logic matches business requirements.
- A test document exceeding the default upload size is uploaded to verify the configuration is active, with no error returned.
- Review parsing logs to confirm the table parsing mode retains the complete structure, and no table content is split into scattered text.
