What the data for this category looks like
Engineering consulting research report data mainly comes from industry standards released by industry associations, government bidding project ledgers, engineering budget and cost documents, and special technical disclosure documents. The update rhythm changes with project progress and policy adjustments, with no fixed cycle. Most documents are a mix of structured and semi-structured formats, containing fields such as project number, construction location, quantity of work, cost details, technical parameters, policy basis, etc. Units include cubic meters, square meters, ten thousand yuan, working hours, etc. Some documents include technical attachments in PDF or CAD formats.
What constraints do these characteristics impose on the model integration and configuration link
The mixed semi-structured format of engineering consulting research reports requires that adaptation rules supporting multi-field parsing be configured during model integration. The lack of a fixed update cycle requires that a real-time synchronization trigger logic be configured for the knowledge base associated with the model. The diversity of fields and units requires enabling unit recognition and association verification in the model configuration. The large span of single document lengths and possible large attachments may cause the context to exceed the model limit, so targeted document chunking rules need to be configured.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Adapts to the context requirements of split single documents for engineering consulting research reports, avoiding truncation of key cost and technical fields |
UPLOAD_FILE_MAX_SIZE | 500 MB | Compatible with large engineering documents with CAD attachments, preventing upload failures |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Matches the long text processing time required for parsing engineering documents, preventing mid-process timeout interruptions |
Chunk size | 1000–1500 characters | Adapts to the semi-structured paragraph length of engineering research reports, retaining complete associations between fields and units |
Similarity threshold | 0.75 | Filters low-relevance non-engineering retrieval results, focusing on target project and standard documents |
Rerank result count | Top 3 entries | Engineering consulting scenarios require precise matching of project parameters, reducing interference from redundant results |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to conduct tests on your own samples before finalizing the settings.
Three Common Mistakes
- Phenomenon: Context overflow errors occur after uploading large engineering research reports, or retrieval results truncate key quantity of work and cost fields. Cause: Targeted chunking rules for long documents are not configured, and general short text segmentation parameters from generic scenarios are used directly.
- Phenomenon: Retrieval results from Chinese knowledge bases fail to accurately match engineering professional terms, resulting in semantic deviations. Cause: A Chinese model adapted to the professional domain is not selected, and a general basic model is used for configuration.
- Phenomenon: After adding the
avatarfield to the model configuration file, the platform interface fails to load the custom icon. Cause: The icon link uses a format other than PNG or JPG, or the link does not have public access permissions.
How to Confirm Successful Configuration
- A single long document is uploaded, and whether the parsing result is correctly split without truncation of key fields is checked.
- A retrieval request containing professional terms and units is submitted, and whether the returned results accurately match the target content is verified.
- The model configuration interface is viewed, and it is confirmed that the custom icon has loaded normally with no loading failure prompts.
- The knowledge base synchronization action is triggered, and it is confirmed that newly added documents can be normally retrieved and called.
