What Data for This Category Looks Like
Documents supporting consumer building materials marketing content primarily originate from brand-owned product manuals, dealer promotional materials, offline event electronic files, and industry supporting promotional materials that underpin financial institution home improvement installment, home insurance, and similar services. Update cycles align with new product launches and promotional activities. Monthly updates are standard, with temporary materials added during peak marketing seasons. Most documents use PDF or DOCX formats, with structures including product parameters, application scenario descriptions, price ranges, and distribution policies. Fields cover specific specifications, weather resistance ratings, unit usage, and more, using industry-standard units such as square meters, kilograms, and liters.
Constraints on Document Parsing and Chunking
The mixed text-image layout and parameter-binding characteristics of consumer building materials marketing documents create multiple constraints for parsing and chunking. First, embedded product parameter tables must retain their full structure, to avoid separating parameters from their associated units and numerical values. Second, promotional materials often include temporarily effective clauses. Chunking processes must identify activity cycle nodes to prevent truncation of critical time-sensitive information. Third, some documents contain mixed cross-category parameters, such as combined tile and coating specifications. Precise matching of field ownership is required to avoid misaligned information after chunking. Additionally, image captions in documents often include dimension annotations. These must be synchronized with their corresponding text blocks to prevent separation of visual and textual information.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Consumer building materials marketing documents often include high-resolution product photos and scene renderings, resulting in large individual file sizes. 500 MB covers the upload needs of most standard promotional materials |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Table parsing and multi-page text extraction for long documents take significant time. 120 seconds prevents parsing interruptions due to timeout |
maxChunkSize | 800–1200 characters | Product parameter blocks and scenario descriptions in consumer building materials documents have balanced lengths. This range ensures complete single-block information and facilitates subsequent retrieval |
chunkOverlap | 100–150 characters | Product parameters and application scenario descriptions are closely linked. Overlapping chunks prevent loss of cross-block information |
enableTableParse | Enabled | Documents contain numerous embedded product parameter tables. Enabling this setting retains full table structure and field correspondence, preventing parameter splitting |
externalFilePushEnabled | Enabled | Adapts to scenarios where financial institution partner dealer systems batch upload consumer building materials promotional materials, supporting external systems to actively push files and trigger parsing and chunking |
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 individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Issue: After server deployment, uploading a file results in a 404 error returned by the document parsing node. Cause: The local environment uses relative paths to store temporary uploaded files. After deployment to a server, the relative path mapping relationship fails, causing the parsing node to fail to locate the target file.
- Issue: In the parsed chunking results, product parameters are separated from their corresponding units and numerical values. Cause: Table parsing configuration is not enabled, or the chunk length is set too small, splitting parameter-bound rows within tables.
- Issue: Files pushed by external systems do not automatically trigger parsing and chunking processes. Cause: The external file push enable configuration is not enabled, or the pushed file format is not supported by the current parsing engine.
How to Verify Proper Configuration
- Upload a single consumer building materials marketing document matching the expected business volume, check the upload progress and file reception status in backend logs to confirm the upload configuration is active.
- Upload a DOCX document containing parameter tables, review the parsed text content to confirm table structure and field completeness meet business requirements.
- Trigger an external system push of a test file, check whether the knowledge base list automatically adds the corresponding file to confirm the external push configuration is active.
- Review the text fragments of the chunking results to confirm that adjacent blocks contain overlapping content, and that no separation of parameters and units has occurred.
