What the Data for This Category Looks Like
Internal office data for general contracting of residential construction projects mainly comes from project management systems, labor attendance systems, material entry ledgers, construction logs, visa forms, and weekly progress reports. Data updates follow project construction milestones. Labor attendance data is updated daily. Material entry records are synchronized per batch. Visa forms and weekly progress reports are updated weekly.
Documents are stored classified by section, time, and responsible entity. Fields include section number, team name, material batch number, visa amount, and construction progress node identifier. Document length varies widely, from short attendance records of tens of characters to hundreds of pages of special construction plans.
What Constraints Do These Characteristics Impose on Multi-turn Dialogue and Prompt Engineering Workflows
Data sources are scattered across multiple business systems. Multi-turn dialogue must call relevant entries across data sources. Prompt engineering must explicitly specify the business module scope for retrieval to avoid mixing up data from different sections.
The wide range of document lengths means overly long contexts can cause the model to mix up key information, so the context window length for multi-turn dialogue must be limited. There are many dedicated fields and business terms, so prompt engineering must include field extraction rules to ensure the AI can accurately match project-specific data.
Frequently updated business data requires the knowledge base synchronization cycle to match milestones. Multi-turn dialogue must support real-time retrieval of the latest data to avoid using outdated information.
How to Set Configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Maximum context window | Previous 10 turns of dialogue + current retrieval results, total length no more than 8000 characters | Residential construction project documents vary widely in length, and overly long contexts can cause the model to mix up key information |
chatId | Bind to the unique section identifier of the project | Ensure coherent context for multi-turn dialogue within the same project, avoid mixing up data across projects |
| Single search limit | Top 6 retrieval results | Residential construction project data is scattered, too many results will dilute valid business information |
| Question optimization | Enabled, calibrated based on actual testing | There are many terms in the residential construction field, optimization can improve retrieval matching accuracy |
| Dialogue timeout period | 120 seconds | Retrieving residential construction documents requires loading multiple types of business data, a longer timeout prevents mid-conversation interruptions |
variables | Bind to department permission identifiers | Restrict dialogue access scope, comply with permission control requirements for internal office work |
Three Common Misconfigurations
- Symptom: A 503 error pops up when uploading local construction logs, labor attendance forms, and other files, while uploading knowledge base files proceeds without issues. Cause: The temporary storage path for local file uploads is not configured, or the path permissions are insufficient, causing file parsing requests to fail to route properly.
- Symptom: When using a strict question-answering template, retrieval returns image address links from the knowledge base, and an "answer not found" prompt is displayed; switching to other templates allows normal reply generation. Cause: The strict question-answering template only matches text-based knowledge base entries, and no format compatibility rules for image links are configured, leading to matching failures.
- Symptom: When calling the API to initiate a dialogue, an error "No permission to operate this dialogue record" is returned. Cause: The department permission identifier bound to the project via
variablesis not configured, causing cross-department dialogue requests to be blocked.
How to Verify the Configuration is Properly Set Up
- Initiate consecutive multi-turn dialogue bound to the same project identifier, check whether the
messagesarray is spliced in turn order, and whether the context is automatically updated as the dialogue progresses. - Upload dedicated documents for residential construction projects, confirm that the file parsing and retrieval processes proceed without issues.
- Switch between different question-answering templates, verify whether the reply logic for knowledge base entries of different formats complies with configuration requirements.
- Initiate a dialogue using an account not belonging to the project, confirm that the permission interception mechanism triggers normally.
