What data for this category looks like
Refractory material financial report data comes primarily from public industry association statistics, annual reports of listed refractory material enterprises, and special production and sales announcements. Updates follow a quarterly core cycle. Annual reports disclose complete production capacity and detailed cost structure breakdowns. Most documents are in Word or PDF format, with standardized internal fields. These fields include refractory product production capacity, single furnace lining service life, raw material purchase unit price, unit energy consumption, and others. Common units are tons, yuan per ton, kilowatt-hours per ton, and similar metrics. Some segmented category reports include attached tables for furnace condition testing.
Constraints on document parsing and chunking
Standardized technical terminology and multi-dimensional associated data in refractory material financial reports require accurate recognition of combined proper nouns during parsing. Incorrect term splitting must be avoided. Tables of capacity and cost data include cross-field associated content. The row and column structure of these tables must be preserved during chunking. Losing this structure will break data corresponding relationships. Most financial reports divide business segments by chapter. Batch parsing must adapt to fixed chapter layouts. Some enterprise financial reports adjust field positions, so non-standardized field recognition must be supported. Some documents embed furnace condition line charts. Numeric data inside these charts must be extracted. Only extracting text content will lead to missing critical data.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Single segments of refractory material financial reports must contain complete associated data such as production capacity and unit price. 800-1200 characters covers complete data blocks for a single business line, and prevents term splitting or broken data associations. |
custom_chunking_rule | Bind Numbered Headings with 3 Adjacent Lines | Most refractory material financial reports divide business segments by chapter. Binding headings with adjacent business data preserves data context, and prevents cross-chapter chunking. |
PARSE_TABLE_ENABLE | Enabled | Capacity and cost tables in financial reports contain multi-dimensional associated data. Enabling table parsing preserves row and column structure, and avoids data disorganization from plain text splitting. |
PARSE_IMAGE_OCR_ENABLE | Enabled | Some financial reports include embedded furnace condition charts. OCR recognition extracts numeric data from these charts, and supplements content missing from plain text parsing. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large annual reports from refractory material enterprises include multiple attachments. 600 seconds covers full parsing duration, and prevents timeout interruptions. |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Annual reports include large industry research attachments. 1000 MB covers most bulk upload scenarios. |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Each scenario requires individual analysis. It is recommended to test with your own samples before finalizing settings.
Three common configuration errors
- Symptom: After uploading a Word or Excel file, the parsing log shows unsupported format, or the knowledge base returns a file link that throws an error when clicked. Cause: The
PARSE_OFFICE_ENABLEconfiguration is not enabled, or the uploaded file format exceeds the platform's supported range. - Symptom: After enabling OCR, image-related content is still missing from model responses. Cause: The
RECALL_IMAGE_CONTENTconfiguration is not enabled, or image context-associated chunks were not preserved during chunking. - Symptom: After setting a custom chunk length, chunk results do not match expectations. Cause: The unit for
segment_lengthwas not specified as characters, the unit was incorrectly set to lines, or chunking was not combined with the report's heading rules.
How to verify correct configuration
- Upload a single standard refractory material enterprise annual report. Confirm parsed text blocks include complete production capacity and unit price fields, with no term splitting errors.
- Check the parsing log to confirm the table parsing switch is active. Confirm table content was not converted to plain text with disrupted structure.
- Upload a financial report with embedded charts. Confirm chunk results include OCR-extracted chart numeric data.
- Bulk upload 3 identically formatted financial reports. Confirm parsing durations all stay within the
PARSE_FILE_TIMEOUT_SECONDSsetting, with no timeout errors.
