Multi-turn Dialogue and Prompt Engineering for Steel Trade Intelligent Due Diligence Reports

The data for steel trade intelligent due diligence reports primarily comes from factory quality certificates issued by steel mills, road and railway

What Data for This Category Looks Like

The data for steel trade intelligent due diligence reports primarily comes from factory quality certificates issued by steel mills, road and railway logistics waybills, port manifests, bank settlement vouchers, and industrial and commercial public information of upstream and downstream enterprises. Data update frequency follows trade batches; documents for a single trade are synchronized and updated after fulfillment. Most documents are structured tables paired with scanned attachments. Core fields include the trader’s unified social credit code, steel grade, specification and model (such as Φ16mm HRB400), transaction quantity (unit: ton), settlement unit price (yuan/ton), delivery location, payment cycle, and some documents also include the number and results of third-party quality inspection reports.

What Constraints These Characteristics Impose on Multi-turn Dialogue and Prompt Engineering

Professional fields and specialized units for steel trade due diligence data require multi-turn dialogue to guide users to clarify field references, preventing confusion between parameters of different steel specifications. Long documents containing multi-stage waybills require multi-turn dialogue to retain sufficient context for associating trade data across different batches. Prompts must limit output scope to stop the model from generating irrelevant content. Decentralized data that requires verification across each stage requires multi-turn dialogue to gradually guide users to supplement missing document information. Prompts must clearly mark core fields for verification. Data update frequency varies by trade batch, requiring prompts to prioritize the most recently uploaded document data.

Configuration Settings

Configuration ItemRecommended Value RangeRationale
maxContext8000–12000 charactersSteel trade due diligence report documents are lengthy, requiring sufficient context to link professional fields and stage information across multi-turn dialogue
chunkSize1000–1500 charactersSteel trade documents have numerous fields and professional specifications. Segments that are too long disrupt field associations, while overly short segments lose the contextual logic of upstream and downstream trade
similarityThreshold0.75–0.85Low-match, non-steel trade data must be filtered, while similar documents of the same category must be retained to support due diligence analysis
reRankTopNTop 3–5 resultsSteel trade document data has strong relevance; a small number of highly matched documents can cover information needs for core due diligence stages
toolCallMaxTurn3–5 timesSteel trade due diligence requires gradual verification of multi-stage data including qualifications, logistics, and settlement. Multiple tool calls can supplement missing document information
promptTemplateOnly generate due diligence reports based on uploaded steel trade document data. Clearly mark field units. Prompt for supplementary corresponding documents if data is missingRestrict model output scope, adapt to unit requirements for professional steel trade fields, and avoid generating unsubstantiated content

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. It is recommended to test on your own samples before finalizing settings.

Three Common Mistakes

  • Phenomenon: Obvious discrepancy between tool call results and native platform dialogue effects. Cause: The promptTemplate has not been adjusted for steel trade professional fields, causing the model to fail to correctly identify specialized terms such as steel grades and specification models.
  • Phenomenon: Workflow dialogue logs show no content. Cause: The logConversation configuration item is not enabled, or maxContext is set too small, causing context to be truncated early and logs to fail to generate properly.
  • Phenomenon: Model testing works normally in a docker deployment environment, but workflow calls fail. Cause: The API key of the corresponding large model is not bound in the workflow node, or toolCallMaxTurn is set beyond the context cache threshold limited by container memory.

How to Verify Proper Configuration

  • Upload a real steel trade document, trigger multi-turn dialogue, and check whether the model can correctly identify specialized fields such as steel grades, specification models, and quantity units.
  • View the workflow dialogue log panel to confirm that multi-round interaction context and tool call records are generated normally.
  • Adjust the similarityThreshold value, test recall results under different thresholds, and confirm that irrelevant data is filtered out and valid document information is retained.
  • Simulate a dialogue scenario with missing fields, and check whether the model prompts for supplementary corresponding document information and generates substantiated content.
