What this type of data looks like
Sources for carbon steel research reports include monthly statistical materials from national industry associations, spot daily reports from domestic commodity trading platforms, and industry tracking reports and in-depth research releases. Update frequency follows three patterns: spot price and inventory data is updated daily, industry weekly reports are updated weekly, and in-depth research reports are released on an as-needed basis. Document structures include market trend modules covering carbon steel grades, benchmark prices, and average daily output, supply and demand balance analysis, downstream demand breakdown, and cost fluctuation interpretation. Core fields focus on specific grades and physical statistical metrics. Standard units include yuan/ton, ten thousand tons, thousand cubic meters, and similar units.
Constraints on model integration and configuration
The multi-source and structured characteristics of carbon steel research reports create multiple constraints for model integration and configuration. Documents combining structured tables and unstructured analysis require enabling the structured parsing switch to extract directly callable fields. The high update frequency of spot data requires configuring a short knowledge base synchronization cycle to balance real-time performance and resource usage. Document lengths vary widely, from hundreds of words in weekly tracking reports to tens of thousands of words in in-depth reports. Reasonable chunking parameters must be set to avoid truncation of critical data. Cross-source unit consistency requirements mandate configuring data normalization rules to unify statistical standards across different channels.
Configuration Recommendations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
enableStructuredParse | Enabled | Carbon steel research reports contain large numbers of structured price, output, and inventory tables. Enabling this switch extracts structured fields for direct use by models |
chunkSize | 800–1200 characters | Single-paragraph analysis content in carbon steel research reports typically ranges from 500 to 1000 characters. This range preserves complete supply and demand analysis logic and avoids truncation of critical data |
chunkOverlap | 100–150 characters | Structured tables in carbon steel research reports often span pages. Overlapping intervals ensure the integrity of table data |
knowledgeBaseSyncInterval | 12 hours | Carbon steel spot prices are updated daily, and industry research reports are updated weekly. A 12-hour synchronization cycle balances real-time performance and resource consumption |
rerankTopN | Top 6 results | Relevant results for carbon steel research reports typically cluster at the top. Prioritizing recall of documents containing specific grades and prices improves response accuracy |
parseExcelEnable | Enabled | Some carbon steel industry data is released in Excel table format. Enabling this option directly parses structured data from tables |
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 targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Symptom: Tool calls return the
context length exceedederror code 413. Cause: No reasonable chunking was applied to deep carbon steel research reports, resulting in input context exceeding the configured model window limit. - Symptom: When connecting to the MiniMax model,
invalid api keyormodel not supportedis returned. Cause: The exclusive interface domain name and version parameters for MiniMax were not correctly filled in the FastGPT model configuration page. - Symptom: Tool call parsing fails with the prompt
Tool call Parser n. Cause: Structured table data in carbon steel research reports is wrapped inthinktags, and no model output format parameters were configured, leading to parsing failure.
How to Verify Proper Configuration
- Upload a carbon steel spot price weekly report, and check if the parsing result extracts structured fields such as benchmark prices and weekly inventory for grades including Q235 and HRB400.
- Submit the query "What is the current price of carbon steel HRB400", and check if the returned result includes the latest data from the synchronized knowledge base.
- Test the tool call function by entering a query containing multiple sections of research report content, and check that no context overflow error occurs.
- View the synchronization logs on the model configuration page, and confirm that the knowledge base automatically synchronizes the latest carbon steel industry data on a 12-hour cycle.
