What the Data for This Category Looks Like
Iron ore research reports primarily originate from industry news platforms, port monitoring institutions, steel mill monthly reports, and publicly available data from futures exchanges. Update schedules cover multiple dimensions. Spot price data updates daily. Weekly supply and demand reports are released each week. Monthly inventory and policy interpretation reports are updated monthly. Annual industry trend reports are updated every quarter.
Document structures include modules such as market overview, supply and demand balance sheets, port inventory data, policy impact analysis, and arbitrage models. Exclusive fields include grade, spot price, port inventory, and trading volume. Some research reports include futures contract spread data.
Constraints Imposed on HTTP Interfaces and External Systems
The multi-frequency update requirement for iron ore research reports means interfaces must support precise incremental or full data retrieval within time ranges. This avoids repeated synchronization of invalid content. The standardization requirement for exclusive fields means external systems must complete field mapping during integration. This prevents unit conversion errors that disrupt business decision-making. The high proportion of long documents means the interface parsing link must have sufficient timeout tolerance. It must also support segmented retrieval. The need for multi-data source access means external system integration modules must support configurable multi-source switching. This adapts to research report data formats from different channels.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
SYNC_FREQUENCY | Configure based on report type: Sync spot data hourly, sync weekly reports daily, sync monthly reports monthly | Matches the differentiated update schedule of iron ore research reports, avoids invalid retrieval that consumes resources |
RECALL_TOP_K | Top 10-20 entries | Iron ore research reports cover rich content dimensions. Sufficient recall volume covers segmented query needs for market, supply and demand, policy, and other topics |
SIMILARITY_THRESHOLD | 0.75-0.85 | Balances matching accuracy for technical terms and result coverage. Avoids low-relevance results interfering with professional analysis |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to parsing duration for long-form research reports, prevents parsing interruption for large reports due to timeout |
UPLOAD_FILE_MAX_SIZE | 500 MB | Supports complete upload of large industry research report files, covers full data synchronization requirements |
API_RATE_LIMIT | 100 requests per minute | Adapts to conventional call frequencies for enterprise-level external systems, avoids interface overload |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfiguration Issues
- Symptom: The interface returns a
413 Request Entity Too Largeerror. Cause: TheUPLOAD_FILE_MAX_SIZEconfiguration was not adjusted. Large research report files cannot be uploaded or synchronized because they exceed the default limit. - Symptom: Research report fields returned by the interface have inconsistent units. For example, prices are shown in US dollars in some cases and yuan per wet ton in others. Cause: Standardized field mapping was not configured. Data sources with inconsistent formats from multiple channels were directly integrated.
- Symptom: The dataset remains in the indexing state for a long time. Cause: Local data source synchronization dependencies were not configured for intranet deployments. Research report data retrieval via external networks causes timeouts. Or the
PARSE_FILE_TIMEOUT_SECONDSsetting is too short to complete parsing of long documents.
How to Verify Proper Configuration
- Call the test interface with exclusive keywords for iron ore research reports. Verify that returned result fields include exclusive identifiers such as grade and port inventory, and that units meet business requirements.
- Check the dataset synchronization log. Confirm that research report retrieval matching the configured
SYNC_FREQUENCYupdate schedule was completed, with no timeout or failure errors. - Simulate an external system call to the interface. Verify that the number of returned results falls within the range configured for
RECALL_TOP_K, and no abnormal status codes are returned. - Test uploading a single iron ore research report file larger than 200 MB. Confirm that the interface returns a success status, with no file size limit exceeded prompts.
