What the data for this category looks like
Crop farming financial report data primarily comes from periodic reports of publicly traded agricultural enterprises, industry monitoring documents from agricultural and rural authorities, statistical materials from industry associations, and production ledgers from large-scale planting bases. Update frequency varies by document type: enterprise financial reports are released quarterly and annually, industry monitoring data is updated monthly or quarterly, and production ledgers are updated per production cycle. Document formats include CSV tables of regional planting area and yield per unit, PDF annual industry analysis reports, and structured cost accounting documents. Common fields include crop name, planting area, total yield, unit cost, with corresponding units of mu, ton, kilogram, and yuan.
Constraints Imposed on Document Parsing and Chunking by These Characteristics
The multi-type document characteristics of crop farming financial reports create clear constraints for parsing and chunking. For CSV regional planting data, the association between fields and their corresponding rows must be preserved to avoid splitting cross-row field combinations. PDF industry reports often mix text analysis and data tables, so text paragraphs and table content must be distinguished to avoid separating chart titles from their corresponding data blocks. Long-cycle annual reports must be split by theme to avoid combining cross-quarter analysis content and regional data into a single chunk. In addition, the binding relationship between fields and units must be fully retained to prevent parsed values from being separated from their units, which would reduce the accuracy of subsequent financial report analysis. Batch-uploaded planting ledgers require unified parsing formats to accommodate differences in field order across different ledgers.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
maxChunkSize | 800–1200 characters | Crop farming financial reports often contain long text analysis and dense data tables. This range balances the completeness of information in a single chunk and retrieval accuracy |
chunkOverlap | 100–150 characters | Retains cross-chunk field associations and analysis context, and avoids splitting table headers from their corresponding row data |
parsePdfTableMode | structured | Adapts to mixed tables and analysis text in crop farming financial reports, and preserves the structured field and unit binding relationship of tables |
csvFieldDelimiter | , or calibrated via actual testing | Adapts to the delimiter format of most publicly available crop farming CSV documents, and avoids incorrect field splitting |
UPLOAD_FILE_MAX_SIZE | 500 MB | Covers the upload requirements for large files such as annual industry reports and batch planting ledgers |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to the parsing time required for multi-page PDF financial reports and batch CSV files |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by document format, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Scenario: After upgrading the platform version, uploading crop farming CSV financial reports returns a
413 Request Entity Too Largeerror. Cause: The new version adjusted the default value of theUPLOAD_FILE_MAX_SIZEparameter by default, and did not synchronously adapt to the upload requirements of existing large-file ledgers. - Scenario: When integrating minerU as a custom document parsing tool, crop names and unit cost fields from crop farming financial reports cannot be extracted correctly. Cause: No crop farming-specific field mapping rules were added to the minerU configuration, and the default parsing rules do not cover the unique fields of this category.
- Scenario: When calling the API to create a file collection for a knowledge base, the PDF parsing parameter is not specified, and the returned chunk results do not retain the unit fields of tables. Cause: The
parsePdfTableModeparameter in the API request was not configured asstructured, and structured table parsing was not enabled.
How to Confirm Configuration is Correct
- Upload a single crop farming annual financial report PDF, view the parsed chunk list, and verify that the field and unit binding relationship of the table is retained to confirm that the parsing configuration is effective.
- Upload batch CSV-format planting ledgers, check that the chunk results fully retain the field data for each row, and confirm that the delimiter configuration matches the document format.
- Call the API to create a knowledge base file collection, add the
parsePdfTableModeconfiguration item to the request parameters, and check whether the returned chunk results conform to the expected structured parsing logic. - Upload a single large-size planting ledger file, check whether the upload and parsing processes complete normally, and confirm that the timeout and size limit configurations adapt to the current document scale.
