Data Profile for This Category
Marketing content data for building construction projects is primarily sourced from project approval documents, floor plan design drawings, building material supplier materials, pre-sales promotional materials, and project progress reports.
Updates follow no fixed schedule. They trigger alongside project milestones, including land acquisition notices, groundbreaking ceremonies, pre-sale license issuance, building material price adjustments, or marketing campaign updates.
Supported document formats include PDF, CAD exports, Word brochures, and Excel building material lists. Document structures typically include project overviews, floor plan parameters, construction standards, surrounding amenities, and cost breakdowns.
Common fields include total construction area, construction duration, building material model numbers, and more. Standard engineering units are used, such as square meters, days, and yuan per square meter.
Constraints Imposed on Deployment and Upgrade
The multi-source, dispersed formats and long-document nature of building construction marketing content require parsing parameters that support multiple formats like CAD and PDF during deployment. This prevents loss of text from professional drawings.
The non-fixed update schedule requires upgrade phases to support incremental synchronization and milestone-triggered updates. This reduces resource usage from full synchronization operations.
Documents contain specialized engineering fields and long text passages. Properly configured segmentation and recall parameters are required to avoid content truncation or redundant recall.
Additionally, multi-format documents have large upload sizes. File upload limit parameters must be adjusted to meet the storage needs of building construction drawings.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300-600 seconds | Building construction project documents include multi-page professional drawings and long text, so parsing takes longer time |
UPLOAD_FILE_MAX_SIZE | 2000 MB | CAD drawings and floor plans for building construction projects are generally large in file size |
Recall count | Top 8-12 entries | Building construction marketing content needs to cover project details, so a sufficient number of matching entries must be recalled |
Similarity threshold | 0.75-0.85 | Filter redundant content unrelated to building construction projects, retain accurately matched professional information |
DOCKER_IMAGE_TAG | v4.8.10 | Stable version adapted for building construction project scenarios, avoids compatibility issues with newer versions |
MYSQL_CONNECT_TIMEOUT | 30 seconds | Handles database connection latency when processing large volumes of data in building construction knowledge bases |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Knowledge base search returns empty results. Cause: No fallback logic for empty searches is configured, and incremental synchronization is not triggered when building construction project documents are updated. This causes knowledge base content to be outdated.
- Symptom: The management backend fails to start after Docker upgrade. Cause: The mount path configuration of the original management backend image is not retained in
docker-compose.yml. Directly replacing the image causes path conflicts. - Symptom: An incorrectly configured
OPENAI_BASE_URLport still allows normal access to external interfaces. Cause: Outbound port validation rules are not enabled, and the proxy layer does not block invalid port requests.
How to Verify Proper Configuration
- Upload a building construction project floor plan PDF. Check if the parsed text includes complete floor plan parameters and annotations. Confirm that the parsing configuration is effective.
- Trigger a knowledge base incremental synchronization. Check the number of new entries in the synchronization log. Confirm that the update logic is running normally.
- Configure a fallback reply for empty searches. Initiate a query with no matching results. Check if the preset fallback content is returned. Confirm that the logic is effective.
- Check the Docker container status. Confirm that both the management backend and database containers are running. Confirm that port mapping configurations match the preset values.
