What the Data for This Category Looks Like
Teams obtain documents related to power grid equipment project financing and cooperative marketing for the finance, insurance, and wealth management industries primarily from internal manufacturer product manuals, public bidding technical specifications, industry association standard documents, and project case materials. Update rhythms align with product iterations, bidding project progress, and industry standard revisions. There is no fixed update cycle, but core parameter documents update every six months to one year. Most documents use a mixed text and image layout, contain large numbers of structured tables, and include fields such as equipment model, rated voltage, rated current, external dimensions, and weight. Units primarily use industry standard metric values including kilovolts (kV), amperes (A), millimeters (mm), and kilograms (kg).
Constraints These Characteristics Impose on Document Parsing and Chunking
The traits of power grid equipment marketing documents create multiple constraints for the parsing and chunking process. Ordinary parsing tools often make unit conversion errors or field splitting deviations when processing structured tables with precise parameters and dedicated units. The mixed text and image layout can split parameter descriptions from their corresponding values during chunking, which reduces subsequent retrieval accuracy. Bidding documents uploaded in batches have inconsistent formats, so the system must support different technical specification layouts. Document updates follow no fixed cycle, so the system must dynamically adapt to newly added equipment models and parameter fields.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Segment Length | 800–1200 characters | Adapts to the length of long parameter descriptions and table blocks in power grid equipment documents, avoiding splitting critical parameter groups |
Overlap Chunk Ratio | 10%–15% | Retains parameter association information between adjacent chunks, preventing splitting of cross-chunk equipment model descriptions |
Enable Enhanced PDF Parsing | Enabled | Adapts to the complex mixed text and image layout and embedded table structure in power grid equipment documents, restoring complete parameter content |
Table Multi-Vector Support | Enabled | For the large number of parameter tables in documents, treats each table row as an independent vector unit to improve retrieval accuracy |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing time required for large bidding documents, avoiding timeout interruptions |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Allows uploading batches of large project documents and product manuals |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Parsing results fail to restore embedded tables after enabling
Enable Enhanced PDF Parsing. The cause is that the minerU dependency is not correctly configured in the local deployment environment, and the enhanced parsing module fails to load properly. - Retrieval results omit some parameter fields after enabling
Table Multi-Vector Support. The cause is that the system does not correctly identify structured tables in the document, and still chunks tables as plain text without generating independent vector units. - Uploading large product manuals that exceed the platform's default size limit fails. The cause is that the
UPLOAD_FILE_MAX_SIZEparameter is not adjusted, so the upload exceeds the platform's default single-file upload limit.
How to Confirm Proper Configuration
- Upload a power grid equipment marketing document containing structured parameter tables, and check whether all fields and corresponding units remain fully intact after parsing.
- View the knowledge base parsing logs to confirm that the
Enable Enhanced PDF Parsingmodule has no dependency error messages and functions normally. - Test batch uploading multiple bidding documents with different layouts, and confirm that all parsing tasks complete normally without interruptions.
- Search for specific equipment models and parameters in the document, and confirm that returned results include complete associated descriptive content.
