What the data for this category looks like
Carbon steel financing daily report data comes from domestic commodity financing monitoring systems and bank corporate credit data interfaces, and is updated daily. Documents include these fields: report date, carbon steel category (such as hot-rolled coil, rebar), daily financing scale, financing subject, delivery location, and remarks. Financing scale is measured in ten thousand yuan. Some documents include a month-on-month change range field. Document lengths vary significantly. It is recommended to confirm based on sample statistics or actual testing prior to finalizing. Some documents present core data in table form.
Constraints for Knowledge Base Retrieval and Recall
The multi-category and multi-field nature of carbon steel financing daily reports requires precise matching of categories and fields during retrieval. This prevents generalized recall. The daily update requirement means the recall mechanism must prioritize returning the latest documents. This stops outdated data from interfering with analysis results. Structured table documents require retaining full field integrity during chunking. Damaging the table structure will cause field matching to fail. Numeric financing scale fields must support exact matching. This avoids precision loss from format conversion.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
recallTopK | Top 12-15 results | There are many carbon steel categories. This setting covers enough retrieval results to avoid missing target categories |
chunkSize | 800-1200 characters | Carbon steel daily reports have many fields. This chunk length preserves field integrity and avoids damaging table structures |
similarityThreshold | 0.75-0.85 | Carbon steel data has high precision requirements. A low threshold introduces irrelevant results. A high threshold reduces valid recall |
rerankTopN | Top 6-8 results | This screens accurate results, balancing recall coverage and result relevance |
UPLOAD_FILE_MAX_SIZE | 200 MB | Single carbon steel financing daily report files usually do not exceed this size. It supports batch upload requirements |
PARSE_SEGMENT_RULE | Segment by field | This preserves document field integrity and avoids damaging table structures during chunking |
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 specific analysis. It is recommended to conduct testing on sample datasets before finalizing settings.
Three Common Mistakes
- Issue: No matching carbon steel category data appears in retrieval results after importing into the knowledge base. Cause: No rule for precise matching by category fields is configured, leading to insufficient generalized recall coverage.
- Issue: An error prompt pops up when clicking the document link returned by the knowledge base, indicating that only .txt and .m format files are supported. Cause: The original uploaded document was not converted to a platform-supported format, or link content was not correctly extracted during parsing.
- Issue: A 400 status code is returned when calling the synchronization interface. Cause: Synchronized document fields do not match the standard format of carbon steel financing daily reports, leading to parameter verification failure.
How to Verify Proper Configuration
- Upload a standard carbon steel financing daily report file, input a specific category keyword to run retrieval, and confirm returned results include the target category and corresponding field data.
- View the parsed document preview in the knowledge base to verify the table structure and field integrity have not been damaged.
- Adjust the retrieval keyword to different carbon steel categories, and test that financing data for each corresponding category can be recalled.
- Click the returned document link to confirm no format error pop-up appears.
