What the data for this category looks like
Special steel financing daily report data mainly comes from daily financing statistics submissions from the national special steel industry association, financing record ledgers from regional steel trading enterprises, and credit loan certificates from partner banks. Common document formats include PDFs with multiple nested tables, standardized Excel daily reports, and some PDFs converted from scanned documents. Single-document page counts vary widely. It is recommended to count or test with your own samples before finalizing decisions. Core fields include special steel category (such as bearing steel, mold steel), financing subject, credit amount (unit: ten thousand RMB), pledged special steel inventory (unit: tons), financing term, loan date. Some documents include embedded images of material quality inspection reports. Full daily financing data from the previous day is updated every early morning.
Constraints on Document Parsing and Chunking
The multiple nested tables in special steel financing daily reports will cause standard document parsing engines to fail to correctly split cross-cell financing information, leading to field misalignment. Embedded material quality inspection report images require supporting OCR parsing capabilities. Otherwise, specific specification parameters of pledged assets cannot be extracted. Daily batch-updated documents require consistent parsing and chunking logic, to avoid differences in chunk boundaries across batches of documents. Daily reports in scanned document format need to adapt to low-resolution text recognition. Otherwise, recognition accuracy of core fields will fluctuate. The multi-field structure for segmented special steel categories requires prioritizing aggregation of information by financing subject or category during chunking, to avoid splitting complete financing data for the same subject.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_NESTED_LEVEL | Level 3 | The table nesting level of special steel financing daily reports is mostly 2-3 levels. This configuration can accurately split cross-cell financing information and avoid field misalignment |
ENABLE_OCR_PARSE | Enabled | Daily reports include quality inspection report images in scanned format. OCR is required to extract material parameter text embedded in images |
MAX_PARSE_CHUNK_SIZE | 800–1000 characters | Complete information for a single financing subject is approximately 600-900 characters. This range ensures chunks include complete subject and pledged asset information |
BATCH_PARSE_MAX_FILES | 50 files per batch | Matches the daily batch-updated document count, to avoid parsing timeouts caused by too many files in a single batch |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Parsing PDFs with multiple nested tables requires longer processing time. This configuration covers the parsing duration of most documents |
TABLE_EXTRACT_STRATEGY | Aggregate by subject | Core information of special steel financing daily reports is grouped by financing subject. This strategy ensures financing data for the same subject is aggregated into a single semantic chunk |
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. It is recommended to test with your own samples before finalizing settings.
Three Common Errors
- Phenomenon: Exporting a knowledge base from an old server as Excel and importing it to a new server results in inconsistent parsing results compared to the original server. Cause: The "Retain original chunk structure" option was not checked during import, or parsing configurations on the new server differ from those on the old server.
- Phenomenon: After uploading a special steel financing daily report with embedded quality inspection report images, the parsing result does not extract text content from the images. Cause: The
ENABLE_OCR_PARSEconfiguration is not enabled, or the OCR parsing module failed to load properly. - Phenomenon: Parsed chunks have spliced information across financing subjects, and cannot split semantic chunks by category. Cause: The
PARSE_TABLE_NESTED_LEVELconfiguration value is lower than the actual nesting level of the document, leading to incorrect table splitting logic. Refer to the paragraph depth configuration instructions for version 4.9.10 to adjust.
How to Confirm the Configuration is Properly Set
- Upload a test special steel financing daily report that includes nested tables and embedded images, and check if fields in the parsing result are complete, with no misalignment or missing content.
- View the chunk preview list after knowledge base parsing, confirm that each chunk corresponds to complete information for a single financing subject, with no spliced content across subjects.
- Batch upload 50 test documents, confirm that all documents complete parsing, with no batch timeout or parsing failure errors.
- Check the knowledge base parsing logs, confirm that the OCR parsing module was called normally, with no related error messages.
