What the data for this category looks like
Iron ore investment research data comes primarily from public industry index platforms, port customs clearance data, steel mill purchase ledgers, futures delivery warehouse announcements, and professional research reports. Structured data includes daily updated spot quotes, weekly port inventory, and monthly supply and demand balance sheets. Fields cover grade, origin, loading/unloading port, and transaction price. Units are mostly yuan per wet ton and percentage. Unstructured data is mostly PDF-format industry research reports, including policy interpretations and supply and demand trend analysis. Update frequency varies by data source: spot quotes are updated daily, and research reports are released as needed.
What constraints do these characteristics impose on deployment and upgrade
The multi-type and strong timeliness of iron ore investment research data creates multiple constraints for deployment and upgrade. The daily update feature of structured data requires configuring incremental sync tasks during deployment, to avoid excessive resource usage from full syncs. Unstructured research reports have large differences in length. When upgrading the document parsing module, long text segmentation logic must be supported, to avoid truncating critical information. Differences in update rhythms across data sources require retaining compatible configurations for multiple scheduled tasks during upgrades. Adding new data sources does not require rebuilding the entire sync link. Additionally, the strong timeliness of price data requires reserving interface bandwidth for real-time data access during deployment. Core data links must not be interrupted during upgrades.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Iron ore industry research reports are typically lengthy, prevents parsing processes from timing out |
Segment Length | 800–1200 characters | Balances semantic completeness of long texts and vector recall accuracy, avoids semantic fragmentation from overly short segments |
Number of Retrieved Results | 10–15 | Meets multi-dimensional information coverage needs for investment research scenarios, avoids missing key supply and demand and price data from too few retrieved results |
Number of Reranked Returned Results | 5–8 | Focuses on core investment research conclusions, reduces invalid information interference, and aligns with analysts' information screening habits |
Incremental Sync Interval | 3600 seconds | Adapts to the daily update feature of spot quotes, ensures data freshness while reducing sync resource consumption |
UPLOAD_FILE_MAX_SIZE | 200 MB | Covers upload needs for most industry research reports and port inventory reports, prevents large file upload failures |
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, and it is recommended to test on your own samples before finalizing values.
Three common mistakes
- Phenomenon: After importing a JSON-format knowledge base configuration, the knowledge base selection dropdown is empty, and the target library cannot be selected directly. Cause: The
KNOWLEDGE_BASE_DEFAULT_SOURCEparameter is not configured correctly, or thesource_idfield in the JSON file does not match the existing knowledge base ID in the platform. - Phenomenon: The Reranker container fails to call normally after startup, and the log prompts an
invalid access tokenerror. Cause: TheRERANKER_ACCESS_TOKENparameter is not correctly obtained and configured, or the token has expired. - Phenomenon: A connection timeout error is returned when calling a locally deployed large model, and the log shows a
Connection refusedstatus code. Cause: TheLOCAL_LLM_API_BASEparameter is not filled in correctly, or the local large model service has not opened access permissions for the corresponding port.
How to confirm the configuration is correct
- Upload a CSV file of iron ore spot quotes, check if the parsed text fully retains core fields such as grade, origin, and price, to confirm that the segment length configuration meets expectations.
- Trigger an incremental sync task, check if the sync log contains the latest spot quote data of the day, to confirm that the incremental sync interval configuration takes effect.
- Initiate an investment research-related query, check if the number of returned results matches the
Number of Reranked Returned Resultsconfiguration, to confirm that the Reranker service is called normally. - Check the system language settings, confirm that the interface is displayed in Chinese, to verify that the
DEFAULT_LANGUAGEparameter is configured correctly.
