What Data for This Category Looks Like
Special steel marketing and production documents for supply chain financial services of financial institutions are mainly sourced from internal product manuals, material test reports, customer quotation sheets, industry standard specifications, as well as marketing materials from offline exhibitions and online promotions. The update rhythm of documents changes with product specification iterations and marketing activity adjustments, with no fixed cycle. Document structures include long text chapters and dense numerical tables. Fields include grade, chemical composition, mechanical performance parameters, delivery status, and application scenarios. Some marketing documents also include temporary promotion information and customer cases.
Constraints Imposed by These Characteristics on Document Parsing and Chunking
The dense tables and multi-field attributes of special steel documents require retaining table structures during parsing. Otherwise, the corresponding relationship between composition and performance data will be lost. Repeated basic grade introductions and scattered application scenarios in long documents can cause automatic chunking to split related content, leading to incomplete recalled information during question answering. Temporary promotion content mixed with standard product parameters in marketing materials requires precise distinction of chunk themes to avoid recalling irrelevant content. Numerical fields with multiple units also require retaining unit associations during chunking to prevent parameter confusion.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_MODE | Retain complete table structure | Special steel documents contain a large number of tables for composition ratios and performance parameters. Splitting tables will lose field correspondence |
CHUNK_SIZE | 800–1200 characters | Parameter information for a single special steel grade is concentrated. This length can fully include the core parameters and application descriptions of a single grade |
CHUNK_OVERLAP | 100–150 characters | Prevents loss of associated grade parameter information across chunks, and ensures coherent context during recall |
PARSE_FILE_MAX_SIZE | 2000 MB | Adapts to upload requirements for large special steel enterprise standard manuals and full-series product manuals |
ENABLE_AUTO_CHUNK | Disabled | Special steel documents have fixed chapter divisions. Manual chunking can accurately match the scenario themes of marketing 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 available samples before finalizing.
Three Common Mistakes
- Phenomenon: After uploading a special steel product manual, recalled content during question answering is split and scattered, and cannot fully match the complete parameters of a grade. Cause: Table retention mode is not enabled, and automatic chunking splits tables into single-row or single-column fragments, losing field correspondence.
- Phenomenon: After uploading a multi-column Excel format special steel composition or quotation sheet, a large number of data misalignments or empty fields appear in the parsing result. Cause: Correct table parsing mode is not configured, and the default parsing logic disrupts the correspondence of multi-column data.
- Phenomenon: After uploading a single special steel marketing document, irrelevant documents from previous uploads are mixed into knowledge base recall results. Cause: Historical cache reuse option during parsing is not disabled, leading to old document content being loaded and processed together.
How to Verify Proper Configuration
- Upload a typical special steel product manual PDF, review the parsed chunk list, and confirm each chunk contains a complete set of grade parameter groups, with no separately split table fragments.
- Upload a multi-column special steel composition Excel table, review the parsed text content, and confirm the correspondence between each column of data is not disrupted.
- Upload a single special steel document, then upload the same type of document again, check the parsing log, and confirm only the currently uploaded document is processed, with no historical document content loaded.
- Test input of a parameter query for a special steel grade, confirm recalled chunks include complete relevant context information, with no scattered or misaligned content.
