What the Data for This Category Looks Like
Special steel investment research data sources include internal production systems, industry association grade standard libraries, spot trading platforms, and downstream customer feedback documents. There are three update cadences:
- Raw material price data is updated in real time.
- Daily production reports and quality inspection reports are updated per shift.
- Industry grade standards and research reports are updated quarterly or annually.
Document structures include structured parameter reports with fields such as carbon content, yield strength, rolling temperature, using units %, MPa, and degrees Celsius. They also include unstructured long-form research reports and customer requirement descriptions. Single long documents can span dozens of pages.
Constraints Imposed on Context and Token Management
The multi-type and highly dense structured nature of special steel data creates multiple constraints for context and token management. Structured reports have high field density, so per-document token consumption is higher than common categories. When splicing multiple recall results, token quota is quickly exhausted. Real-time updated raw material price and production data require frequent synchronization to context, increasing token refresh frequency and concurrent consumption. Investment research comparison demands across furnace numbers and batches require recalling multiple long documents, which easily exceeds the model's context window limit, leading to truncation of key parameters.
Configuration Settings
| Configuration Item | Recommended Range | Rationale |
|---|---|---|
maxContextToken | 8000–12000 | Adapts to the token consumption of single long special steel documents, reserving sufficient space for splicing multiple sets of structured parameters and research report content |
Segment Length | 800–1200 characters | Balances the field recognition accuracy of special steel structured data and the rationality of long-form research report segmentation, avoiding single-segment token overflow |
Number of Recalled Items | Top 6–8 | Covers multiple sets of comparison parameters required for special steel investment research, while controlling total token consumption within the context window limit |
Similarity Threshold | 0.72–0.78 | Matches the high-precision requirements of special steel parameters, filtering irrelevant data while ensuring sufficient valid samples are recalled |
Number of Rearranged Returned Items | Top 3–5 | Retains the most relevant long documents after reranking, avoiding redundant token consumption that impacts model inference efficiency |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing duration of large special steel production ledgers and quality inspection reports, preventing premature termination of long file parsing |
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 the reader’s own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: When the number of recalled items is set above 10, the large language model returns replies without relevant context, and the
context truncatedfield appears in logs. Cause: The total token count of multiple recalled special steel test reports exceeds themaxContextTokensetting, so the system automatically truncates content and no valid context is passed to the large language model. - Phenomenon: When uploading a single production ledger over 200MB, the interface prompts "parsing timed out". Cause:
PARSE_FILE_TIMEOUT_SECONDShas not been adjusted to a duration suitable for long documents, causing large file parsing to terminate before completion. - Phenomenon: When segment length is set to 2000 characters, the large language model returns answers with messy parameter formats. Cause: Special steel structured data has high field density, long segments cause uneven token allocation, making it impossible for the model to correctly identify the association between parameters.
How to Verify Proper Configuration
- Upload a typical special steel quality inspection report, check the segmentation results in the knowledge base preview, confirm that the segment length matches the set value.
- Initiate a query involving comparison of parameters across multiple furnace numbers, check the
contextTokenfield in backend logs, confirm that the total token count does not exceed themaxContextTokensetting. - Adjust the number of recalled items to the recommended range, verify the relevance of search results and the matching of item count.
- Test the token consumption of a single round of conversation, confirm that the model's context window overflow error is not triggered.
