What Data for This Category Looks Like
Iron ore research report data sources include national steel industry associations, domestic commodity exchanges, public reports from global mining enterprises, and research reports from commodity consulting firms. Update schedules vary: spot prices and port inventory data are updated daily. Weekly industry reports are released each week. In-depth reports are released monthly or on demand. Temporary reports are generated for sudden supply and demand changes or policy adjustments. Most documents are in PDF format. Some include structured Excel attachments. Core fields include port name, total inventory, transaction price, grade level, and transportation cost. Units are tons, yuan per wet ton, grade, and yuan per kilometer, respectively.
What Constraints Do These Characteristics Impose on Citation and Traceability
The multi-source dispersion, inconsistent update schedules, and diverse formats of iron ore research reports create multiple constraints for citation traceability. Reports from different sources must be bound with exclusive identifiers. For example, exchange reports must be associated with contract codes. Industry association reports must be marked with release document numbers to avoid traceability confusion. Daily updated spot data requires precise hourly timestamps. Monthly in-depth reports only need to retain the release date. PDF documents require extraction of page numbers and paragraph positions. Excel attachments must be linked to specific cell locations. This ensures traceability points to clear content fragments. Traceability for structured fields must be bound to the source document of the corresponding field. General references to entire research report content must be avoided.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall count | top 8-12 results | Iron ore research reports contain multi-dimensional structured data. This range covers relevant inventory, price, and supply and demand analysis content, avoiding missing key information |
chunk length | 800-1200 characters | Iron ore research reports often include long tables and coherent industry analysis. This chunk length preserves contextual association around tables, avoiding splitting that disrupts data integrity |
similarity threshold | 0.75-0.85 | Iron ore research reports contain many professional terms and homogeneous analysis content. This threshold filters irrelevant results while retaining sufficient matching fragments |
parse_file_timeout_seconds | 300 seconds | Large iron ore research report PDFs or Excel attachments include multi-page structured data. A longer timeout ensures complete parsing of all content |
enable_source_citation | enabled | Iron ore research reports have high compliance requirements. Clear traceability ensures cited content can be traced back to specific locations in the original document |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: The context citation area only displays plain text, and cannot render tables and bold formatting from research reports. Cause: The "preserve document format" configuration was not enabled during knowledge base upload. Structured content in iron ore research reports is flattened, making renderable Markdown fragments impossible to generate.
- Phenomenon: No citation sources are returned after submitting a question, or cited documents are irrelevant to the question content. Cause: The
similarity thresholdis set too high, filtering out matching iron ore research report fragments that meet requirements. Or therecall countis set too low, failing to cover relevant structured data. - Phenomenon: Citation display cannot be turned off in conversations. Cause: The "show citation sources" switch was not turned off in the conversation configuration. Or
enable_source_citationwas not set to disabled in the global configuration.
How to Confirm Configuration Is Correct
- A test iron ore research report document is uploaded. Parsed content fragments are reviewed to confirm structured tables and coherent paragraphs are not overly split.
- A specific question about iron ore port inventory or transaction prices is submitted. Returned result citation traceability is verified to mark document names, specific location information, and release times.
- Recall-related configurations are adjusted. The number of recall results under different values is tested to ensure matching results cover relevant content for target indicators.
- Citation traceability configuration is turned off. The conversation interface is checked to confirm citation sources are no longer displayed, verifying the configuration takes effect as expected.
