What the data for this category looks like
Vehicle industry research report data primarily comes from public reports published by securities firm automotive industry research institutes, regular financial reports and temporary announcements of listed automotive enterprises, and public statistical materials from domestic automotive industry associations.
Update cycles include fixed schedule and trigger-based updates. Fixed schedule updates include monthly sales data and quarterly industry trend reports. Trigger-based updates include special research reports issued when automotive enterprises launch new products or policies are adjusted.
Document structure includes modules such as core vehicle parameters, segmented market sales rankings, competitive product benchmarking analysis, and policy impact interpretation. Standardized fields include cruising range (unit: km), maximum power (unit: kW), recommended retail price (unit: ten thousand yuan), monthly sales volume (unit: units). Some special research reports include segmented regional market data.
Constraints for Model Integration and Configuration Imposed by These Data Characteristics
Long document lengths are common for vehicle industry research reports, some including multi-page charts and parameter tables. These documents may exceed basic context window limits. Adjust segmentation and retrieval strategies to support long text processing.
Research reports contain a large number of professional fields with units, such as cruising range, power, and price. Models must accurately identify values associated with their units to avoid unit mix-up errors.
Some research reports include embedded vehicle photos and sales trend charts. Configure models with multimodal parsing capabilities to ensure returned results correctly associate with image content.
Frequently updated industry data requires configuring a scheduled synchronization mechanism to prevent knowledge base content from lagging behind market developments.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Matches the average length of single vehicle industry research report, avoids truncating core parameters and competitive benchmarking content |
chunkSize | 1000–1500 characters | Preserves association between fields and charts when splitting long documents, reduces information loss across segments |
similarityTopK | Top 8–10 results | Retrieves sufficient multi-dimensional research report content covering segmented vehicle models, sales data, and policy information |
rerankTopN | Top 3–5 results | Filters redundant research reports on the same topic, focuses on the most relevant core conclusions |
enableMultiModal | Enabled | Parses embedded vehicle images and sales charts included in research reports, supports associating image display in returned results |
| `PARSEFILETIMEOUT_SECONDS | 300 seconds | Adapts processing duration for long documents and multimodal parsing, avoids timeout interruptions |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Each case requires individual analysis. It is recommended to test on samples prior to finalizing settings.
Three Common Configuration Mistakes
- Symptom: Model returns results that do not associate with embedded research report images, and only uses text descriptions instead. Cause: The
enableMultiModalconfiguration item is not enabled, or the prompt does not explicitly require prioritizing associated image display. - Symptom: Workflow runs return a
400 Bad Requesterror, with logs showing context length exceeded limits. Cause: ThemaxContextparameter is not adjusted for the long document characteristics of vehicle industry research reports, causing single round requests exceed supported model limits. - Symptom: Unit mix-up appears in retrieved research report results, such as labeling cruising range as "1000 units". Cause: The system prompt does not clearly define binding rules for field units, or the
chunkSizeconfiguration is not adjusted to preserve field association, causing the model to lose unit association information when splitting documents.
How to Verify Successful Configuration
- Upload a typical vehicle industry research report document, check if the parsed segments retain complete core vehicle parameter modules, confirm that the
chunkSizeconfiguration matches the document structure. - Submit a research report retrieval request, check if returned results associate with embedded vehicle images or charts, confirm that the
enableMultiModalconfiguration is active. - Review the knowledge base synchronization logs, confirm that scheduled update tasks run according to preset cycles, verify the trigger logic of the scheduled synchronization configuration.
- Input a test prompt containing multiple fields such as cruising range, power, and price, check the accuracy of returned fields and image association, adjust relevant configuration parameters to meet requirements.
