What data in this category looks like
Data for hotel and catering financing daily reports primarily comes from store POS systems, supply chain reconciliation reports, monthly revenue ledgers, and form files submitted with financing applications. Most files generate updates daily; some chain stores aggregate data weekly. Document formats mainly use XLSX and PDF. Structures include fixed header rows, with fields covering store number, operating period revenue, ingredient procurement costs, daily passenger trips, financing application amount, and approval status. The currency unit is uniformly RMB yuan, passenger traffic uses trips as the unit, and time fields are precise to the calendar day.
What constraints these characteristics impose on document parsing and chunking
High-frequency daily updated files require parsing tools to support fast batch processing, to prevent single-file parsing timeouts. Fixed headers paired with cross-row merged operating data rows demand accurate table structure recognition to avoid incorrect splitting. Multi-field mixed content such as revenue and financing information on the same page requires retaining contextual association during chunking, and must not split the same store’s same-day data. Multi-row XLSX tables may contain blank rows or hidden columns; automatic filtering of invalid content is required while preserving field correspondence. Scanned PDF files may have OCR recognition errors, so parsing logic needs to adapt to fuzzy text.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
PARSE_FILE_ENCODING | utf-8, gbk auto-adapt | Hotel and catering financing daily reports may include files with local encoding formats; auto-adaptation avoids errors like the argument ‘windows-1252’ is invalid encoding |
PARSE_TABLE_MERGE_CELL | Enable merged cell recognition | Daily report tables often have cross-row and cross-column operating period merged cells; enabling this fully extracts the correspondence between headers and data |
PARSE_CHUNK_SIZE | 800–1200 characters | A single daily report entry contains multiple fields; this range retains complete contextual association between a store’s same-day operations and financing information, avoiding disruptive chunking |
PARSE_CHUNK_OVERLAP | 50–80 characters | Daily report data is grouped by time period or store; overlapping chunks ensure associated information across chunks is not lost |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | When batch processing weekly aggregated chain store reports, this prevents single-file parsing timeouts |
UPLOAD_FILE_MAX_SIZE | 50 MB | Weekly aggregated chain store reports may include data from multiple stores; this upper limit covers file sizes for most scenarios |
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 targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three common errors
- Phenomenon: Field misalignment or data loss occurs when parsing multi-row XLSX format tables. Cause: Merged cell recognition configuration is not enabled, leading to incorrect correspondence between cross-row and cross-column headers and data.
- Phenomenon: The
the argument ‘windows-1252’ is invalid encodingerror is thrown during document parsing. Cause: Adapted file encoding parameters are not configured, and the document uses a non-universal encoding format. - Phenomenon: Retrieved chunked content cannot be linked to the specific source document. Cause: Document traceability association configuration is not enabled, and original document metadata information is not retained during chunking.
How to confirm configurations are correctly set
- Upload a standard hotel and catering financing daily report file, check if the parsed table structure fully retains the correspondence between headers and data, and confirm that the merged cell recognition configuration is active.
- Upload test files in different encoding formats, check if parsing logs show encoding error prompts, and confirm that the encoding adaptation configuration works properly.
- Generate chunked knowledge base content, check if each chunk includes identification information of the original document, and confirm that traceability configuration is enabled.
- Batch upload multiple daily report files, check if parsing tasks complete within a reasonable time frame, and confirm that the timeout configuration matches the current business scenario.
