Multi-turn Dialogue and Prompt Engineering for Plastics and Rubber Intelligent Due Diligence Reports

Data sources for plastics and rubber due diligence reports include monthly statistics from industry associations, import and export data updated by

Data Characteristics of This Category

Data sources for plastics and rubber due diligence reports include monthly statistics from industry associations, import and export data updated by the General Administration of Customs in the following month, spot quotes from commodity trading platforms, and ex-factory price announcements from upstream petrochemical enterprises. Update frequencies vary across sources: spot quotes are updated daily, industry association production capacity and operating rate data are updated monthly, and customs import and export data are updated in the first ten days of the following month. Documents are structured by segmented category. Each chapter includes fields such as production capacity scale, upstream raw material dependence, downstream demand proportion, monthly price range, and import and export volume. Most field units are ten thousand tons and yuan per ton. Some cross-border data sources use US dollars per ton as the price unit.

Constraints on Multi-turn Dialogue and Prompt Engineering

Dispersed data sources and inconsistent formats require multi-turn dialogue to first align field mappings across different sources. This avoids confusing similar data with different naming conventions. Differences in data update frequencies require prompt engineering to account for timeliness. Use daily updated sources when asking about current spot prices, and monthly updated industry data when asking about annual production capacity. The large number of easily confused segmented category names requires multi-turn dialogue to first prompt the user to specify the exact category. This prevents cross-category query errors. Differences in field units require prompt engineering to either automatically convert units or confirm the user’s desired unit standard before initiating a query.

Configuration Settings

Configuration ItemRecommended RangeRationale
maxContext8000–12000 charactersSingle plastics and rubber due diligence report often exceeds 3000 characters. Multi-turn dialogue must retain historical context of category, data sources, and query requirements to avoid context overflow
rag_recall_threshold0.75–0.85Names of plastics and rubber segmented categories are easily confused. A higher threshold filters irrelevant recall results and ensures data matching accuracy
file_chunk_size1000–1500 charactersAdapts to context association needs for long fields in plastics and rubber reports, avoiding loss of category association information due to overly short segments
PARSE_FILE_TIMEOUT_SECONDS300 secondsSingle industry report contains data across multiple categories, leading to long parsing times. Prevents premature termination of parsing
session_prompt_triggerFirst session triggerAvoids redundant context caused by repeated loading of prompt content during multi-turn dialogue, and adapts to the fixed query logic of due diligence reports

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 specific analysis, and it is recommended to test on your own samples before finalizing settings.

Three Common Misconfigurations

  • Symptom: System prompt content is repeatedly loaded during multi-turn dialogue, with redundant prompt text appearing in the context. Cause: session_prompt_trigger is not set to First session trigger. By default, system prompts reload with each dialogue turn.
  • Symptom: Automatic recall of plastics and rubber due diligence knowledge base content when initiating a regular conversation unrelated to due diligence. Cause: The RAG recall switch for regular conversations is not disabled, or the knowledge base is not exclusively associated with the dialogue chain for due diligence scenarios.
  • Symptom: 408 Request Timeout error during parsing of large plastics and rubber industry reports. Cause: PARSE_FILE_TIMEOUT_SECONDS is not configured to a value above 300 seconds. Report parsing time exceeds the default limit.

How to Verify Proper Configuration

  • Initiate a query for a specified plastics and rubber category, and confirm that the context window retains the category specification from the prior turn, with no redundant repeated prompt content.
  • Switch to the regular conversation scenario, initiate a query unrelated to plastics and rubber due diligence, and confirm that no content from the due diligence knowledge base is recalled.
  • Upload a plastics and rubber industry report exceeding 3000 characters, wait for parsing to complete, and confirm that no timeout error occurs.
  • Initiate multi-turn progressive queries, such as first asking for the spot price of natural rubber, then asking for the raw material price of its upstream synthetic latex, and confirm that the dialogue chain retains the category information from the prior turn, with no field unit confusion.
