Constraints on Multi-turn Dialogue and Prompt Engineering
Quarterly updated data sources require dialogue flows to trigger periodically, to avoid excessive resource usage from frequent pulls of full historical data. Mixed document types and data structures require prompts to clearly distinguish field rules for different documents, to avoid confusion between ledger record and implementation report filling requirements. Multiple data sources require gradual alignment of data from different systems during multi-turn dialogue, to ensure summary results conform to the standard format of the national emission permit management information platform. Compliance-related error consequences require built-in verification logic in the dialogue flow, to pre-check the match between permit limits and actual emission data.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Context window size | 8000–12000 token | Matches the total character count of quarterly emission ledgers and implementation reports, to avoid truncation of critical compliance fields |
| Retained multi-turn dialogue history count | First 20 dialogues | Covers the full communication flow for a single ledger review, to avoid broken verification logic due to lost context |
| Prompt variable configuration | variables | Injects dedicated parameters such as quarterly cycle and enterprise permit number, to adapt to personalized summary requirements for quarterly updated data |
| Knowledge base recall matching threshold | 0.75–0.85 | Distinguishes emission permit standard documents from other environmental protection materials, to accurately recall compliance basis |
| Interface timeout duration | 120 seconds | Adapts to the time required for pulling and summarizing multiple data sources, to avoid mid-task interruptions |
Three Common Configuration Errors
- A 403 status code is returned when calling the Java interface, and dialogue context cannot be obtained. The cause is incorrect configuration of the
chatIdparameter, failure to bind a valid application access key, or failure to pass valid dialogue history via themessagesparameter. - Generated ledger summary reports use non-standard terminology that does not align with English compliance scenarios. The cause is failure to replace Chinese compliance terms in the prompt template with English expressions via the
variablesparameter. - Uploaded emission permit copies are not correctly recalled by the knowledge base. The cause is failure to configure chunking rules for the corresponding document type, resulting in loss of critical permit limit information after long documents are truncated.
How to Verify Correct Configuration
- Pass the
chatIdparameter when calling the interface, and check whether the returned result includes a dialogue context identifier. - Upload a single-quarter emission ledger document, and verify that the knowledge base recall results include core fields such as permit limits and discharge outlet numbers.
- Modify the prompt template, inject the
variablesvariable, and check whether the generated report automatically fills in the dedicated parameters for the corresponding enterprise. - Set the interface timeout duration to 120 seconds, submit a multi-source data summary task, and verify that no timeout interruptions occur.
