What the Data for This Category Looks Like
Commercial vehicle marketing content data primarily comes from original equipment manufacturer (OEM) public technical documents, regional dealer promotional materials, and user feedback from terminal operation scenarios. Update rhythms vary significantly by material type: vehicle parameter documents are updated annually, regional promotion policies are updated monthly, and short video marketing scripts are updated weekly. Document structures include structured parameter manuals with fields such as VIN, rated load capacity, emission standards, unstructured sales scripts and promotional posters. Field units mostly use industrial standard units like mm, kg, kW. Some regional policy documents include region code fields.
What Constraints Do These Characteristics Impose on Deployment and Upgrade
The multi-source heterogeneous nature and varied update rhythms of commercial vehicle marketing data create multiple constraints for deployment and upgrade workflows. Structured parameter fields are numerous and specific to commercial vehicles, so targeted field mapping rules must be configured to avoid vehicle parameter misalignment from generic document parsing. Material types with different update frequencies require incremental sync configuration during deployment. Upgrade processes must add or adjust scheduled update trigger tasks, without requiring full re-parsing of all materials. The presence of region code fields requires configuring region-based recall filtering rules during deployment, to adapt to regional marketing content push needs. Different material formats need dedicated parsing plugins. Parsing rules must be updated during upgrades to support new document formats.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Commercial vehicle technical documentation has high per-page content and can exceed 100 pages; default timeout values cannot complete full parsing |
UPLOAD_FILE_MAX_SIZE | 20 MB | Individual commercial vehicle public parameter manuals can reach up to 18 MB; setting a reasonable upper limit prevents upload failures |
maxContext | 8000–12000 characters | Commercial vehicle marketing conversations require combining vehicle parameters, regional policies, and user inquiries; longer context improves matching accuracy |
RECALL_TOP_N | Top 8 entries | Commercial vehicle user inquiries focus on specific vehicle configurations; excessive recall distracts users |
SIMILARITY_THRESHOLD | 0.75–0.85 | Commercial vehicle marketing content contains many specialized industrial terms; a higher threshold filters irrelevant matching results |
INCREMENTAL_SYNC_INTERVAL | Every 4 hours | Regional promotion policies are updated monthly; incremental sync balances real-time performance and server resource usage |
The parameter values provided on this page are general recommendations to serve as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Issue: An
ETIMEDOUTerror appears when parsing commercial vehicle technical manuals, and the task status shows timeout. Cause: ThePARSE_FILE_TIMEOUT_SECONDSconfiguration is not adjusted. Default short timeout values cannot complete parsing of long documents. - Issue: Regional policy documents are not synced to the knowledge base after deployment, and latest promotion information cannot be retrieved. Cause: Only full initial sync is performed, incremental update rules for
INCREMENTAL_SYNC_INTERVALare not configured, and subsequent updated regional materials are not covered. - Issue: The model call interface returns
500 Internal Server Error, and the service restarts continuously without limit. Cause: Model access endpoint and key parameters are not configured correctly, so the service cannot start normally.
How to Confirm Configurations Are Correct
- Upload a commercial vehicle parameter PDF document, check the parsing task status and extracted fields to confirm the parsing timeout configuration is active.
- Manually update a regional policy document, verify if the knowledge base completes incremental updates within the set sync interval to confirm the incremental sync configuration is active.
- Call the interface of an external regional policy website, check FastGPT logs to confirm successful content retrieval, verifying external access permission configurations are correct.
- Initiate a conversation about commercial vehicle configuration, review the number of recalled knowledge base entries to confirm recall and similarity threshold configurations are active.
