What This Category of Data Looks Like
Marketing documents for refractory materials targeting the finance sector originate primarily from custom refractory supporting solution manuals for financial clients, third-party test reports, industry standard documents, and marketing promotional materials. Document updates synchronize with product formula iterations, industry standard revisions, and updates to marketing materials for financial scenarios, with no fixed cycle. Documents typically contain product grades, chemical composition proportions, physical performance parameters, application instructions for financial scenario kilns, test data tables, and compliance markings. Common fields and units include compressive strength (MPa), load softening temperature (℃), bulk density (g/cm³), and implemented standard numbers. Some documents include detailed parameters of kiln adaptation cases for financial data centers.
Constraints Imposed on Document Parsing and Chunking
Refractory material marketing documents for the finance sector contain large numbers of physical parameter tables bound to units, long professional descriptions, and cross-page product comparison content. Some documents also include compliance-related markings for finance scenarios. Parameters and units are tightly bound. Splitting them will lose the meaning of the parameters. Parsing must retain the integrity of table structures and parameter groups. Long paragraphs mostly involve continuous descriptions of kiln adaptation scenarios. Improper splitting will break scenario logic. Some documents display complete test data for a single product across multiple pages. Cross-page chunking must be avoided to prevent information fragmentation. Product grades and corresponding parameters in marketing materials must maintain contextual association. Parameter-grade mismatches must be prevented after chunking.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2048 MB | Refractory material documents often include high-definition test images and long text. Larger file uploads must be supported to avoid file size limit errors |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing long documents and documents with complex tables requires longer processing time to prevent mid-parsing timeouts |
chunk_size | 800–1200 characters | Adapts to the length of refractory material parameter groups and scenario descriptions. Prevents splitting of parameter and scenario associations |
chunk_overlap | 100–150 characters | Retains parameter context between adjacent chunks. Prevents professional parameter groups from being split apart |
enable_table_parse | Enabled | Retains the structure of chemical composition and performance parameter tables in documents. Prevents unordered splitting of table content |
custom_separator | ["\n\n", "### ", "#### "] | Matches chapter headings and paragraph separators in refractory material documents. Aligns with the native structure of the documents |
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 on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: A file size limit error pops up when uploading a 3MB refractory material marketing PDF. Cause: The
UPLOAD_FILE_MAX_SIZEconfiguration item is not adjusted. The default threshold is smaller than the uploaded file size. - Symptom: After setting custom separators, chunking results either merge multiple product parameter paragraphs or split a single set of performance parameters into multiple independent chunks. Cause: The chapter hierarchy and parameter group separation rules of refractory material documents are not matched, and the segment length is not adapted to the average length of parameter groups.
- Symptom: In the parsed chunked content, chemical composition parameters and their corresponding units are completely separated. Cause: The table parsing function is not enabled. The parameter tables in the document are split into scattered text, losing the binding relationship between parameters and units.
How to Verify Proper Configuration
- Upload a single typical refractory material document. Check the upload status and parsing logs to confirm the file is not blocked due to size limits.
- View the parsed chunk preview. Check whether the structure of parameter tables is complete and whether parameters and units are bound together.
- After adjusting the
chunk_sizeandcustom_separatorconfigurations, compare chunking results across different settings. Confirm that paragraphs and parameter groups are not abnormally split or merged. - Test the parsing time of long documents. Confirm that no timeout interruptions occur. Adjust the
PARSE_FILE_TIMEOUT_SECONDSconfiguration as needed.
