What this type of data looks like
IT service marketing content data primarily comes from vendor official solution manuals, customer case documents, service quotation sheets, SLA agreements, and similar materials. Update cycles align with business iterations, with syncs when new solutions launch or quotations are adjusted. Document structures are typically chapter-based, mixing native text PDFs, scanned offline solution materials, multi-sheet Excel tables, and text-image hybrid content. Fields include service module names, delivery cycles, unit prices, customer industries, and case revenue data. Units cover business-specific identifiers such as ten thousand yuan, man-days, and quarters.
What constraints these characteristics impose on document parsing and chunking
Mixed document formats require parsing tools to handle native text and scanned pages differently, to avoid wasting resources on repeated OCR of native content. Multi-sheet Excel stores quotation and case data, so the parsing process must support extracting all worksheet names and corresponding content to avoid missing associated business data. Numeric fields with units require retaining the correspondence between fields and units after parsing, to prevent loss of data semantics. Text-image mixed marketing manuals require distinguishing text content and visual charts, to avoid including image areas of architecture diagrams and schematic diagrams in the OCR scope, which would interfere with main text parsing results. Frequently updated documents also need to support batch parsing timeout and capacity configurations to maintain parsing efficiency.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Meets the parsing duration requirements for large IT service solution documents, prevents parsing interruptions due to excessive length |
ocr_strategy | Skip OCR for native text pages, enable OCR for scanned pages | Matches the common structure of IT service marketing documents that mix native PDFs and scanned manuals, reduces unnecessary computation |
chunk_max_length | 800–1200 characters | Balances contextual coherence for long paragraph solution descriptions and tabular data, adapts to the granularity requirements of retrieval scenarios |
excel_sheet_parse | Extract all sheet names and content | Meets the parsing needs of multi-sheet stored IT service quotations and case lists, avoids missing associated data |
keep_table_format | Enabled | Retains the structure and unit correspondence of quotation and revenue data tables in IT service documents, prevents field loss |
skip_image_ocr | Enable for schematic diagrams and architecture diagrams | Prevents visual charts in marketing documents from being incorrectly OCR'd, retains the original image display path |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- When a scanned IT service solution PDF is uploaded, the parsing result only includes page numbers without valid text content. The cause is that the scanned page OCR configuration is not enabled, and only native text content is recognized, resulting in lost text on scanned pages.
- After parsing a text-image mixed service manual, the architecture diagram area generates redundant meaningless text via OCR, disrupting the original text layout logic. The cause is that the skip image OCR rule is not configured, and all image areas are included in the OCR scope.
- When a multi-sheet service quotation Excel is uploaded, the parsing result only includes content from the first worksheet. The cause is that the multi-sheet extraction configuration is not enabled, and only the first worksheet is parsed by default.
How to confirm the configuration is correct
- Upload a mixed IT service solution PDF with both native text and scanned pages, check whether the parsed result includes complete text content on scanned pages.
- Upload a service quotation Excel with multiple sheets, check whether the parsed result includes all sheet names and corresponding data.
- Upload a service manual with architecture diagrams, check whether the parsed result retains the original image links and does not include redundant OCR text.
- Upload a single large IT service document, check the completion status of the parsing task, and no timeout-related errors appear.
