What This Category of Data Looks Like
Data sources for this category include publicly disclosed regular corporate reports and industry regulatory monitoring data. Updates follow a fixed quarterly, semi-annual, and annual schedule. Temporary announcements are updated in real time. Document formats include official financial reports in PDF, operational data tables in Excel, and operational briefings in Word. Excel documents typically contain multiple sheets corresponding to revenue classification, cost structure, store operations, duty-free product category proportions, and other business categories. PDF financial reports contain nested tables across multiple chapters, with some chapters including data visualizations. Fields include duty-free sales (unit: ten thousand yuan / hundred million yuan), off-island shopping passenger trips, license qualification information, product gross profit margin, operational cost proportion, and other relevant metrics.
Constraints Imposed on Document Parsing and Chunking
Multi-sheet Excel documents for the duty-free category require the parsing process to accurately identify the business attribution of each sheet. This prevents unrelated content from being mixed into chunks. Nested tables and visual content in PDF financial reports require retention of the original row and column structure. This avoids chaotic parsed content. Real-time updated temporary announcements require the parsing process to support fast batch processing. Cross-format documents including PDF, Excel, and Word require a unified chunking logic. This ensures content coherence. Highly specialized financial report fields require retention of the binding relationship between fields and business data during chunking. This avoids breaking business logic after splitting.
Configuration Settings
The following table lists recommended configuration values and their rationales:
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_EXCEL_SHEET_ENABLE | true | Duty-free financial report Excel files usually contain multiple business sheets. Enabling this setting allows separate extraction of valid content from each sheet, avoiding business logic confusion caused by combined parsing |
PARSE_PDF_ENHANCE | true | Duty-free financial report PDF files contain nested tables and visual content. Enabling enhanced parsing preserves the row and column structure of tables, preventing chaotic content parsing |
CHUNK_SIZE | 800–1200 characters | Duty-free financial report fields are highly specialized. This segment length preserves the complete logic of a single business data entry, avoiding breaking the binding between fields and data after splitting |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large duty-free financial report documents, including multiple sheets and charts, take a long time to parse. This duration covers the complete parsing process |
UPLOAD_FILE_MAX_SIZE | 500 MB | Some annual duty-free financial reports include multiple pages of charts and detailed data. This upper limit meets requirements for uploading large files |
PARSE_EXCEL_SHEET_WHITELIST | ["revenue details","cost composition","store operations"] | Filters non-business-related system sheets, retaining only core business chunks and reducing invalid content |
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 Misconfigurations
- Phenomenon: After parsing an Excel document, only the content of the first sheet is returned. The names and data of other business sheets cannot be extracted. Cause: The
PARSE_EXCEL_SHEET_ENABLEconfiguration is not enabled, or no valid sheet whitelist is configured. - Phenomenon: When importing PPT or Word documents, after selecting the PDF enhanced parsing option, the parsed result does not retain the original table and text structure. Cause: PDF enhanced parsing only adapts to PDF format documents. Other formats require corresponding dedicated parsing rules.
- Phenomenon: Importing an Excel file results in a parsing failure, or a CSV file only recognizes two columns of data. Cause: The Excel parsing enable option is not configured, or the column separator for CSV parsing does not adapt to the multi-column data format of duty-free financial reports.
How to Verify Correct Configuration
- Upload a single Excel test file containing multiple business sheets. Check whether the parsed result includes independent chunked content for each sheet.
- Upload a PDF format duty-free financial report test file. Check whether the parsed result retains the row and column structure and text logic of nested tables.
- Upload test documents in different formats. Confirm that the parsed results of each format meet business requirements, and adjust the values of corresponding configuration items.
- View parsing logs. Confirm that the timeout configuration covers the parsing duration of large documents, and no parsing interruption errors occur.
