What This Category’s Data Looks Like
Marketing content data for the optical optoelectronics field targeting the financial industry is primarily sourced from internal enterprise product parameter manuals, sales follow-up documents, exhibition electronic brochures, CSV-format business statistics tables, and multi-level directory marketing materials from Feishu collaboration platforms. Updates occur without a fixed schedule, with sporadic daily updates aligned with new product launches, quarterly business adjustments, or marketing campaign changes. Document structures include long-form text product introductions, multi-column structured parameter tables, collaborative documents with nested multi-level directories, and often mix DOC files and embedded images. Fields cover optical parameters, electronic parameters, product model and batch information, with a variety of specialized units attached.
Constraints for Document Parsing and Chunking
The multi-source, mixed-format characteristics of optical optoelectronics marketing documents require the parsing module to support multiple formats including PDF, Word, CSV, and Feishu documents, while also being compatible with embedded images and DOC files. Multi-column structured CSV tables contain multiple sets of business parameters; extracting only the first two columns will lose core business information. Collaborative documents with nested multi-level directories require recursive retrieval of full content, otherwise marketing materials in subdirectories will be missed. Frequently updated document content requires the chunking module to retain contextual associations between parameters and units, avoiding damage to parameter logic after splitting. The combination of long-form manuals and high-definition images also requires the parsing module to have sufficient timeout fault tolerance and large file processing capabilities.
Configuration Recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500–1000 MB | Optical optoelectronics marketing documents often include high-definition product images and long-form manuals, requiring adaptation for large file uploads |
maxChunkSize | 800–1200 characters | Optical and electronic parameters are often densely arranged; overly long chunk sizes will lose parameter associations, while overly short chunk sizes will damage context |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Parsing large PDF manuals requires a longer duration, to avoid interrupting the parsing process due to timeout |
enableRecursiveParse | Enabled | Marketing materials in Feishu multi-level directories require recursive retrieval of full content to avoid missing subdirectory documents |
parseCsvAllColumns | Enabled | Optical optoelectronics CSV documents contain multiple columns of parameter data; extracting only the first two columns will lose critical business information |
enableImageOcr | Enabled | Product photos and parameter stickers in brochures require OCR recognition to extract hidden text information |
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 individual analysis, and testing against local samples is recommended before finalizing settings.
Common Configuration Errors
- Only extracting the first two columns of data after uploading a CSV file. This occurs because the
parseCsvAllColumnsconfiguration item is not enabled, and the default parsing logic only extracts the first two column fields. - Receiving a 413 error when uploading large files in Docker mode deployment. This occurs because the
UPLOAD_FILE_MAX_SIZEparameter is not adjusted, and the container does not lift the size limit for the corresponding upload port. - Failure to call an external PDF parser after configuration. This occurs because the corresponding key for the external parser is not correctly filled in the system configuration, and the key configuration path is incorrect.
- Only parsing top-level content for Feishu multi-level directory documents, with embedded DOC files and images unable to be retrieved. This occurs because the
enableRecursiveParseconfiguration is not enabled, and theenableImageOcrfunction is not activated.
How to Confirm Proper Configuration
- Upload a test optical optoelectronics CSV parameter document, and verify that the number of parsed data columns matches the original document.
- Upload a PDF product manual larger than 500 MB, and check that the parsing progress completes normally without timeout errors.
- Import a Feishu multi-level directory marketing document package, and check that all subdirectory DOC files and recognized content of embedded images are included.
- After configuring an external PDF parser, upload a test PDF file, and check that the parsing result includes complete text and parameter information.
