What This Category of Data Looks Like
Special steel enterprise financial report data comes from public disclosure platforms of Shanghai, Shenzhen and Hong Kong stock exchanges, and official enterprise announcement channels. Update schedules follow statutory disclosure rules: annual reports are released by the end of April each year. Semi-annual reports are released by the end of August each year. Quarterly reports are updated at corresponding nodes. Temporary announcements are released immediately as operating data changes. Most documents are in PDF format, including sections such as operating situation discussion and analysis, consolidated financial statements, production and sales details. Some documents disclose production and sales data of segmented special steel products. Fields include special steel output, special steel operating revenue, attributable parent company net profit, R&D investment amount, etc. Units are mostly tons and yuan.
Constraints These Data Characteristics Impose on Model Access and Configuration
Special steel financial reports include business split fields for regular steel and special steel. Precise field extraction rules must be configured during model access to avoid mixing regular steel business data into special steel analysis dimensions. Most financial report PDFs have cross-page tables and non-standard typesetting. Segmented parsing parameters adapted to long documents must be configured to avoid field extraction breaks. Batch data update requirements at statutory disclosure nodes require configuring batch processing timeout thresholds and concurrency limits to avoid server overload. Some financial reports disclose segmented product unit price and production capacity data. Custom field mapping rules must be configured to adapt to non-standard financial report field naming.
How to Set Configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_PDF_TIMEOUT | 900 seconds | Adapt to parsing time of special steel financial reports with multiple cross-page tables, avoid long document parsing interruptions |
max_segment_tokens | `800–1200 tokens | Match text length of cross-page tables in special steel financial reports, avoid field extraction truncation |
batch_upload_concurrency | `2–3 concurrent tasks | Adapt to batch financial report upload requirements during statutory disclosure seasons, avoid server resource exhaustion |
custom_field_extract | Enabled, specify "special steel output", "special steel operating revenue" | Accurately extract segmented special steel fields, avoid mixing regular steel business data |
similarity_threshold | 0.75–0.85 | Filter low-relevance financial report fragments, focus on special steel-related analysis content |
embedding_model | Calibrated based on actual document vector matching performance | Adapt to professional term vector expression of special steel financial reports, improve retrieval accuracy |
The parameter values provided on this page are common starting points for configuration. Actual values vary based on material format, data volume and business rules. Specific cases require individual analysis. It is recommended to conduct testing on applicable samples before finalizing configuration.
Three Common Configuration Mistakes
- A
model not founderror is returned during model calls, with a 404 status code. Cause: No model proxy service is configured, local model library is directly connected, and model identifiers supported by the proxy platform are not synchronized and mapped. - Parsed financial report fields include regular steel operating revenue data, or target special steel fields are empty. Cause: Custom field extraction rules are not enabled, and matching conditions for segmented special steel fields are not specified, leading the model to extract general financial report fields.
- A
504 Gateway Timeouterror occurs during batch upload of multiple financial reports. Cause: The `PARSEPDFTIMEOUT parameter is not adjusted, and the default timeout duration is insufficient to complete full parsing of cross-page tables.
How to Confirm Configuration Is Complete
- Upload a single special steel financial report PDF, check the parsed field list, confirm that preset segmented special steel fields are included.
- Initiate a batch upload test, observe system logs, confirm that server resource overload alarms are not triggered.
- Call the model to perform financial report analysis, check that output results only include special steel-related business and financial data.
- Verify that the return status code of the model call is 200, and no
model not foundtype errors occur.
