What the data for this category looks like
Hotel and catering investment research data comes from industry analysis reports, single-store operation ledgers, supply chain purchase price lists, OTA platform passenger flow and revenue data, food safety regulatory policy documents, and more. Update rhythms vary significantly: industry reports are updated quarterly or semi-annually, single-store operation data is updated daily or weekly, and supply chain purchase prices are updated daily or in real time.
Document structures include plain text analysis, structured tables, and mixed-format PDF documents. Structured tables contain fields such as sales per square meter per day, customer unit price, and ingredient cost. Common units are yuan/square meter/day, yuan/kilogram, passengers/day, and similar units.
What constraints these characteristics impose on document parsing and chunking
The mixed-format nature of hotel and catering investment research documents requires parsing tools to support both plain text extraction and structured table recognition. This prevents loss of key structured content such as purchase price lists and revenue details.
Different update rhythms correspond to different parsing trigger requirements. High-frequency updated supply chain data needs to adapt to real-time parsing processes. Low-frequency industry reports can use fixed-cycle parsing triggers.
Professional catering industry terms such as table turnover rate and credit period must be retained intact during chunking. Truncating these terms will cause semantic breaks.
Long-text annual store expansion planning reports require reasonable chunk parameter settings. This avoids disrupting the coherence of business logic.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_MODE | auto | Hotel and catering documents contain mixed structured tables, charts, and plain text. Auto mode can recognize all types of formats |
CHUNK_SIZE | 800–1200 characters | Structured table row content in the catering industry is mostly 300-800 characters long. Long-text analysis report paragraphs are mostly 600-1000 characters long. This range preserves context integrity |
TABLE_PARSE_ENABLE | true | Hotel and catering investment research documents contain a large number of purchase price lists and revenue detail tables. Enabling this retains complete row and column structure |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Annual report PDFs for large chain restaurants typically have 50-100 pages. 300 seconds covers full parsing duration |
CHUNK_OVERLAP | 100–150 characters | Retaining overlapping parts during long-text chunking avoids context breaks, and adapts to the logical coherence of catering industry reports |
PARSER_ENGINE | marker | Hotel and catering documents include cost calculation formulas and charts. The marker engine better recognizes such content |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test against your own samples before finalizing settings.
Three common mistakes
- Symptom: A
504 Gateway Timeouterror occurs when calling the parsing tool. Cause:PARSE_FILE_TIMEOUT_SECONDSis not set to a duration suitable for large catering reports, leading to uncompleted parsing due to timeout. - Symptom: Table fields are empty in the parsed result of an uploaded purchase price list PDF. Cause:
TABLE_PARSE_ENABLEis not enabled, so only plain text is extracted and structured content is lost. - Symptom: The locally deployed parsing tool cannot recognize cost calculation formulas normally. Cause: The parsing image version does not match the online version. For example, using the
v0.1marker image, which does not support the formula formats common in hotel and catering documents.
How to confirm the configuration is correct
- Upload a hotel and catering purchase price list PDF that includes structured tables, and verify that the parsed result retains complete row and column structure.
- Upload a catering operation report PDF that includes cost calculation formulas, and verify that the formulas are recognized and displayed correctly in the parsed result.
- Adjust the chunking parameters, then review the context coherence of the chunking results to confirm no key terms are truncated.
- Check system logs to confirm that no timeout or error status codes occurred during parsing tool calls.
