What the Data for This Category Looks Like
Vehicle industry research report data primarily comes from in-depth industry reports published by securities research institutions, production and sales announcements publicly disclosed by automakers, Ministry of Industry and Information Technology motor vehicle product announcements, and statistical materials from automotive industry associations. Update frequency varies by report type: regular industry research reports are updated quarterly and monthly, with temporary documents added when new vehicles are launched or policies are adjusted. Most documents include structured parameter tables, sales breakdowns, cost analysis, and policy interpretations. Standardized fields include curb weight (kg), CLTC driving range (km), torque (N·m), and other similar parameters, supplemented by lengthy qualitative analysis content.
Constraints Imposed on Multi-turn Dialogue and Prompt Configuration
The structured parameters and update characteristics of vehicle industry research reports create multiple constraints for multi-turn dialogue and prompt configuration. Multi-turn dialogue must bind vehicle identifiers in context to avoid confusion between parameters with units such as driving range and torque for different models in subsequent user questions. Frequent temporary document updates require prompt configuration with dynamic recall rules for the latest versions, preventing calls to outdated data. The large volume of long-text analysis content requires limiting the context window length to avoid redundant content interfering with subsequent question logic. Document structures with many nested tables require prompts to explicitly bind parameters to corresponding vehicle models during parsing, preventing parameter misalignment.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Adapts to the long-text analysis content of vehicle industry research reports and multi-turn dialogue context requirements, avoiding exceeding model window limits |
SIMILARITY_THRESHOLD | 0.75–0.85 | Filters low-relevance research report fragments, retaining highly matched parameters and analysis content for user questions |
RECALL_TOP_K | Top 6–8 entries | Balances coverage of research report information and context redundancy, avoiding excessive documents interfering with dialogue logic |
PARSE_TABLE_ENABLE | Enabled | Vehicle industry research reports contain a large number of structured parameter tables, requiring extraction of fields, units, and corresponding vehicle model information |
UPLOAD_FILE_MAX_SIZE | 50 MB | Adapts to the document size of a single in-depth research report, allowing upload of complete industry analysis documents |
SYSTEM_PROMPT | Must bind vehicle models and parameter units involved in the question, prioritize calling the latest uploaded research report documents | Clarifies parsing rules, avoiding parameter confusion and calls to outdated data |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: After upgrading to version 4.9.0, refreshing the dialogue page shows empty conversation records, only displaying the new conversation creation button. Cause: Session persistence module is not enabled during private deployment, or the
SESSION_STORAGE_ENABLEconfiguration item is not set to enabled. - Issue: AI replies indicate no files have been uploaded, but vehicle industry research reports have already been associated with the corresponding knowledge base. Cause: The system prompt does not explicitly require calling documents from the associated knowledge base, or the configured knowledge base ID does not match the actually uploaded documents.
- Issue: Unable to switch between different vehicle model research report knowledge bases in real time during dialogue. Cause: No knowledge base switching trigger node is configured in the workflow, or no mapping relationship between vehicle identifiers and corresponding knowledge bases has been established.
How to Verify Successful Configuration
- Initiate a parameter-specific question for a specific vehicle model, and verify that the reply content includes the associated vehicle model and corresponding parameter units.
- Upload a new version of the research report and repeat the same question, and verify that the reply uses the latest document data.
- Enable multi-turn dialogue, ask different parameters for the same vehicle model in sequence, and verify that the system retains the vehicle model context.
- Attempt to upload a research report document that exceeds the configured size, and verify that the system triggers an upload limit prompt.
