What the Data for This Category Looks Like
Engineering consulting research report data primarily originates from internal project documents of architectural decoration engineering consulting institutions, special consulting reports released by industry associations, bidding announcement documents, and compliance review materials. Update timelines adjust in real time as projects progress; industry overview research reports are released quarterly. Most documents follow a fixed structure: project overview, technical scheme, cost details, compliance analysis. They also include supplementary attachments such as CAD drawings, bill of quantities tables, and BIM model parameter files. Fields include building area, cost amount, construction period duration, and other metrics, with specialized supporting units like square meters, ten thousand yuan, calendar days, plus professional terms such as building seismic fortification level and construction technology standards.
Constraints for Document Parsing and Chunking
Multi-source document formats for engineering consulting research reports require parsing nodes to support PDF, DOCX, and CAD export files, with specific support for parsing embedded tables and vector drawings. Real-time updated project documents must support batch uploads and parsing initiated by external system active pushes, avoiding limitations of only supporting manual single uploads. Fixed chapter structures require chunking processes to retain hierarchical logic, preventing key information from being split across chapters. Specialized fields and units require parsing processes to preserve the association between numerical values and their units, avoiding loss of professional meaning after chunking.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Engineering consulting research reports often include large CAD attachments and multi-page long documents, requiring sufficient timeout to ensure complete parsing |
Chunk size | 800–1200 characters | Single chapter content of engineering consulting research reports is lengthy; this range preserves the integrity of professional paragraphs and prevents splitting across key information |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Supports upload requirements for large CAD drawings and multi-page PDF collections, adapting to large attachment scenarios in engineering consulting projects |
Preserve Chapter Hierarchy | Enabled | Engineering consulting research reports have clear chapter logic; retaining hierarchy helps subsequent retrieval accurately match content from corresponding chapters |
Parse Embedded Tables | Enabled | Cost details and bill of quantities are core information in research reports, requiring complete parsing of embedded table content |
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 Misconfigurations
- Issue: A 404 error occurs when uploading files to trigger parsing after server deployment. Cause: Static file storage path is not configured, and files uploaded by the frontend are not correctly synchronized to the accessible directory of the server parsing node.
- Issue: No embedded table content is present in the parsed document. Cause: The
Parse Embedded Tablesconfiguration is not enabled, so cost lists and quantity tables in engineering consulting research reports cannot be fully extracted. - Issue: Chunking results show spliced content across chapters. Cause: The
Chunk sizesetting is too small, causing key chapter titles and corresponding content to be split, losing contextual association.
How to Verify Proper Configuration
- Upload a single CAD exported PDF document under 200 MB, wait for parsing to complete, then check if complete chapter titles and embedded tables are extracted.
- Check system logs to confirm that parsing requests do not trigger timeout errors, and that the
PARSE_FILE_TIMEOUT_SECONDSsetting meets requirements. - Manually trigger external system file pushes to the knowledge base, check if parsing and chunking tasks start normally and generate corresponding vector data.
- Check the access permissions of the file storage directory, confirm that uploaded file content can be read normally in the server deployment environment.
