What Data Looks Like for This Category
Marketing content data for automotive parts primarily comes from original equipment manufacturer (OEM) product manuals, after-sales spare parts catalogs, vehicle compatibility lists, and dealer promotional materials. Update cycles adjust based on vehicle model refreshes, new product launches, or compliance certification updates. Documents fall into two categories: structured parameter documents and unstructured promotional materials. Structured documents include fields such as OE numbers, compatible model years, torque values (newton meters), and weights (kilograms). Unstructured materials include product images and text, and installation guide video links. Some documents must include environmental certification and compliance test number information.
Constraints Imposed on Deployment and Upgrade Workflows
High structured parameter content requires configuring field extraction rules during deployment, to extract unique identifiers such as OE numbers and compatible model years for deduplication and association. Non-fixed update cycles require supporting incremental synchronization configuration during upgrades, to avoid full data re-imports. The compatible vehicle model field must be linked to a vehicle database, so an interface docking channel must be reserved during deployment. The diversity of video external link formats requires supporting link parsing rules for different platforms during upgrades. Updates to compliance certification fields must trigger partial re-embedding of the knowledge base, to reduce resource consumption. Separate synchronization paths must be configured for multilingual versions of some documents, to prevent content mixing across language versions.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Structured parameter documents and video external link parsing take significant time, so sufficient time must be reserved for completion |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Marketing materials including high-definition images and installation guide videos typically do not exceed this size, to avoid upload blocking |
Segment Length | 800–1200 characters | Balances the integrity of structured parameters and contextual association, to prevent parameters from being split across different segments |
Similarity Threshold | 0.75–0.85 | Accurately matches compatible vehicle models and parameter information for automotive parts, to avoid returning low-relevance results |
EMBEDDING_BATCH_SIZE | 32 | Balances embedding efficiency and memory usage, to meet the demand for batch processing of structured parameter documents |
The parameter values provided on this page are common starting points for configuration setup. 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 Errors
- After upgrading to version 4.14.3, an error
fail to create post presigned urlappears when adding attachment files during conversations. The cause is that object storage configuration parameters were not updated synchronously after the upgrade, leading to abnormal presigned URL generation logic. - After upgrading the platform version, model vendor icons fail to load normally, and a loading failed placeholder is displayed in the interface. The cause is that the upgrade script did not overwrite the static resource directory, so icon files were not synchronized for update.
- It is impossible to accurately calculate the total disk space occupied by a locally deployed knowledge base. The cause is that storage paths for original files, split file chunks, and embedding vectors are not distinguished. Directly counting root directory usage will include unrelated data.
How to Confirm Proper Configuration
- Upload a structured parameter document containing OE numbers and compatible model years, check that parsed fields are fully extracted and that segments match the preset length.
- Initiate a search containing vehicle compatibility keywords, verify that the similarity of recalled results falls within the preset threshold range.
- Run an incremental synchronization task, check that updates only to compliance certification fields trigger partial re-embedding, and that only the embedding vectors of corresponding segments are updated after completion.
- View system logs and object storage upload logs, confirm that no errors related to presigned URL generation appear when uploading attachment files.
