What the Data for This Category Looks Like
Minor metal research report data, intended for institutional financial investors and industry practitioners, is sourced primarily from national nonferrous metal industry associations, futures exchanges, leading mining enterprises, and third-party industry consulting firms. Update cycles cover monthly supply and demand tracking, quarterly supply and demand balance sheet updates, and real-time interpretation documents for sudden policy or market shifts. Document structures include core variety supply and demand data, import and export details, downstream application proportions, price trends, and policy interpretation fields. Most field units are tons or ten thousand yuan per ton. Some specialized sub-varieties include spot delivery standard details.
Constraints on Citation Source and Traceability
The multi-source, dispersed nature of minor metal research reports requires traceability to support precise source matching via publisher tags, to avoid confusion between identically titled reports from different institutions. Coexisting reports with varying update frequencies require traceability to sort content in reverse chronological order, prioritizing the most recent valid material. Specialized units and delivery standards for individual sub-varieties require traceability matching logic to link variety fields and unit parameters, preventing cross-category confusion. The timeliness requirements of real-time interpretation reports require limiting the traceability time window, to ensure returned content meets decision-making needs in financial scenarios.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall count | top 8-12 entries | There are many specialized subcategories of minor metal research reports; excessive recall will introduce redundant content from unrelated categories |
similarity threshold | 0.72-0.85 | Minor metal research reports contain a large number of specialized subfield terms; a threshold that is too low will include matching results from non-target categories |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Some long-term supply and demand balance sheet documents have lengthy content, requiring sufficient time for text parsing |
citation source display format | [Publisher] Publication Date: Document Title | Publishers and publication dates of minor metal research reports have high reference value for industry practitioners |
maxContext | 6000-8000 characters | Individual minor metal research reports have moderate content; overly long context will disrupt precise matching logic |
re-ranked return count | top 4-6 entries | The number of traceability display entries must be controlled to avoid interface information overload |
The parameter values provided on this page are common recommended 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 Misconfigurations
- An interface returns a
200status code but an emptycontentfield after a retrieval request is sent. This occurs because therecall countparameter is not configured correctly, or the value exceeds the maximum number of entries that can be recalled from the knowledge base, resulting in no valid matching content being generated. - Displayed citation sources have messy formatting and garbled characters. This occurs because the
citation source display formatparameter is not configured, or special typesetting symbols in the research report are not filtered during parsing, leading to abnormal output. - Traceability results include research reports from other nonferrous metal categories unrelated to the current query. This occurs because the
similarity thresholdparameter is not set, or the threshold value is too low, causing content from non-target categories to be incorrectly recalled.
How to Confirm Proper Configuration
- Send a retrieval request for a specific minor metal variety, and confirm that the returned results include core content of the corresponding category's research reports.
- Review the returned citation source list, and confirm that the display format matches the preset configuration.
- Verify that all recalled research reports belong to the minor metal category, with no cross-category mixed content.
- Check that all fields returned by the interface have no garbled characters or missing content, and conform to the expected structure.
