What the Data for This Category Looks Like
Iron ore market and yield rate data primarily comes from Dalian Commodity Exchange futures trading data, and daily quote data from domestic mainstream spot trading platforms. Futures data updates every 5 minutes during trading days, while spot data updates once each morning. A standard single data document includes fields such as contract code, trading market, daily highest/lowest price, settlement price, trading volume, position volume, spot benchmark quotation location, and release time. Price-related fields uniformly use yuan per wet ton as the unit. Trading volume and position volume correspond to futures trading lots and spot trading tons respectively.
What Constraints Do These Characteristics Impose on Multi-turn Dialogue and Prompting
Frequently updated data sources require clear distinction between historical knowledge base data and real-time market data during multi-turn dialogue. Prompts must specify the time range and source type of data requested by the user, to prevent the model from calling outdated or mismatched information. Detailed fields and multiple types of data sources require prompts to clearly mark the market type to which the data belongs, to avoid confusion between futures and spot data. The lengthy document structure requires the dialogue context to retain sufficient historical interaction information, ensuring the model can accurately follow up on subsequent user questions and prevent key information loss caused by context overflow.
How to Set Configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Retains key information such as market type and time range specified by the user in multi-turn dialogue, preventing information loss caused by context overflow |
Recall count | Top 3–5 entries | Iron ore market data has a high degree of field subdivision; excessive recall introduces redundant information and impairs the model's ability to extract core fields |
Similarity threshold | 0.75–0.85 | Distinguishes similar field descriptions for futures and spot markets, preventing accidental recall of mismatched data source descriptions |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Prevents knowledge base update failures caused by parsing timeouts when parsing documents containing multiple years of historical market data |
Chunk size | 800–1000 characters | Single iron ore market data documents have many fields; excessively long chunks prevent the model from accurately locating required information |
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, and testing on internal samples prior to finalization is recommended.
Three Common Mistakes
- Phenomenon: Dialogue output contains a large number of markdown punctuation marks such as # and *. Cause: No format filtering rules for dialogue output are configured, and the markdown tags generated by the model are not adapted and rendered by the front end, causing the original symbols to be displayed directly.
- Phenomenon: After calling the dialogue interface, the returned result does not include the
refSourceIdfield. Cause: The configuration item for knowledge base reference tracking is not enabled, or the prompt does not clearly require the model to label reference source related information. - Phenomenon: When using a workflow to process large-scale iron ore market data, task execution times out or produces no valid results. Cause: No batch processing parameters for the workflow are configured, and the single-load data volume exceeds the system processing limit, causing task interruption.
How to Confirm Proper Configuration
- Initiate a multi-turn dialogue that distinguishes between futures and spot markets, and verify that the output clearly marks the data source and corresponding unit.
- Call the dialogue interface, check whether the returned result includes the
refSourceIdfield, and confirm that the reference tracking configuration is enabled. - Upload an iron ore document containing multiple years of historical market data, and verify that the knowledge base parsing task has no timeout errors.
- Trigger a dialogue containing a real-time market request, confirm that the system calls the real-time data source instead of static knowledge base content.
