What the Data for This Category Looks Like
Sources for hotel and catering marketing content documents include store menus, holiday promotion plans, membership system rules, exported files from online group purchase detail pages, and store descriptions on food delivery platforms. Update rhythms align with marketing campaigns: seasonal menus and monthly promotion plans update on a fixed cycle, while temporary activity documents are released as needed. Document structures include plain text notifications, formatted poster PDFs, dish pricing Excel files, membership rule Word documents, and more. Fields include dish name, selling price, activity time, applicable stores, discount intensity, and others. Units include yuan per serving, hours, person-times, and others.
What Constraints Do These Characteristics Place on the Document Parsing and Chunking Link
Diverse document formats require parsing tools to support multiple types including text, tables, and formatted posters, to avoid missing key information such as dish pricing and activity details. Frequently updated marketing content requires chunking logic that preserves contextual associations, preventing coherent promotion rules from being split into unrelated fragments. Differences in field attributes across documents require distinguishing core information from auxiliary content during parsing. For example, store addresses and activity times must not be split into different chunks. Additionally, some documents contain parallel rules for multiple stores. Chunking must ensure complete information for a single scenario, and avoid mixing rules across stores.
How to Configure the Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Hotel and catering marketing documents often contain coherent activity rules and dish combination descriptions. Adapting to this length ensures the integrity of information in a single chunk |
chunk_overlap | 100–150 characters | Ensures key information that spans segments such as promotion time and applicable stores is not truncated, improving contextual relevance |
enable_table_extract | Enabled | Menu pricing tables and group purchase package lists are often stored as tables. Enabling this allows complete extraction of fields and corresponding values |
PARSE_FILE_TIMEOUT_SECONDS | 180 seconds | Large-scale promotion activity documents (including multi-store details) take longer to parse, avoiding parsing failure due to timeout |
parse_format_priority | Prioritize original document structure | Preserves line breaks in poster copy and row-column correspondence of tables, avoiding chaotic formatting after parsing |
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, and it is recommended to test on your own samples before finalizing.
Three Common Errors
- Phenomenon: Chunking results split complete promotion copy into multiple independent fragments, with key information split into different chunks. Cause: Failed to adjust the
chunk_overlapparameter based on the document structure, resulting in adjacent segments failing to retain cross-chunk key associated information. - Phenomenon: Chunked content displayed in the knowledge base cannot be rendered as Markdown format, and table content is displayed as stacked plain text. Cause: Failed to enable the
enable_table_extractconfiguration, or failed to retain original document format tags during parsing. - Phenomenon: After passing in a web link, no document content can be parsed, and only empty parsing results are returned. Cause: Failed to adapt the anti-crawling mechanism of the target web page in version v4.8.13, or the linked page has no publicly crawlable marketing document content.
How to Confirm the Configuration Is Properly Set
- Upload a table document of a store menu, check whether the parsing result completely extracts the row and column contents of the table, confirming that the table extraction configuration is enabled.
- Select a section of promotion copy containing associated information, check whether adjacent chunks retain partially overlapping key content, confirming that the chunk overlap configuration adapts to the document structure.
- Upload multi-format marketing documents, verify whether the format of the parsing result corresponds to the original document's typesetting, confirming that the format parsing configuration meets requirements.
- Upload a single large-scale marketing document, check whether the parsing task is completed within the preset timeout period, confirming that the timeout configuration matches the document size.
