What Data for This Category Looks Like
Special steel research report data primarily comes from public reports released by a national special steel industry association, monthly production and sales reports from leading special steel enterprises, in-depth industry research reports from securities firms, and real-time quotes from spot trading platforms. There are three update schedules: spot price data is updated daily, industry supply and demand research reports are updated weekly or monthly, and long-term capacity planning reports are released irregularly. Document structures typically include fields such as special steel grade details, specification parameters, production, sales and inventory data, downstream application proportions, and import and export statistics. Most use industrial standard units like tons, yuan per ton, and ten thousand tons. Some specialized reports also include technical parameter tables such as metallographic structure and mechanical properties.
Constraints Imposed on Model Access and Configuration
Special steel research reports have dense specialized fields, wide variations in document length, and a large number of industrial terms and standardized units. This creates three constraints for model access and configuration. First, long text and multi-table structures require the model context window to cover complete data segments, to avoid truncating professionally related information. Second, the need for precise matching of segmented specialized fields requires recall and reranking configurations to adapt to the retrieval accuracy of specialized data. Third, differences in update frequencies across report sources require the knowledge base refresh cycle to match data update schedules. Token calculations for model calls must also adapt to field parsing requirements for long texts.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Special steel research reports often include multi-page tables and long paragraphs. The default parsing duration is insufficient for complete parsing. |
maxContext | 16384-32768 token | Covers specialized terminology and long data segments in special steel research reports, avoiding loss of field associations due to context truncation. |
UPLOAD_FILE_MAX_SIZE | 500 MB | Adapts to the combined volume of batch-uploaded industry research reports, supporting batch processing of multiple documents. |
Recall count | Top 8-12 entries | Covers multi-dimensional specialized fields in special steel research reports, improving the completeness of retrieval results. |
Similarity threshold | 0.75-0.85 | Filters low-match non-special steel related reports, retaining precisely matched specialized data. |
Rerank result count | Top 3-5 entries | Focuses on core specialized data, reducing redundant information interference with model inference. |
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. Each scenario requires individual analysis. Testing on local samples is recommended before finalizing settings.
Three Common Misconfigurations
- Symptom: Uploading a special steel research report results in a request failure message in the interface. The log shows an
ETIMEDOUTerror. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted. The default value cannot cover the parsing time required for long documents. - Symptom: After submitting a special steel professional query, the returned results include content with mismatched grades and price units. Cause: Appropriate
maxContextand recall configurations were not set, causing the model to fail to associate context fields. - Symptom: After uploading a special steel research report PDF with embedded industrial images, the grade and specification data within the images are not retrieved. Cause: The
PARSE_IMAGE_ENABLEDswitch was not enabled, and supporting OCR parsing models were not configured.
How to Confirm Proper Configuration
- Upload a typical special steel research report including production and sales tables and technical parameters. Confirm parsing completion status and time. Verify that the
PARSE_FILE_TIMEOUT_SECONDSsetting meets document processing requirements. - Submit a query including special steel grades and price units. Verify the completeness and accuracy of specialized fields in returned results. Confirm that the
maxContextand recall configurations are active. - Test uploading a research report with embedded industrial images. Confirm that image content is extracted and included in the retrieval scope. Verify that OCR and image parsing configurations are correct.
- View model call logs. Verify that token consumption matches the
maxContextsetting. Confirm that there are no conflicting parameter configurations.
