What the Data for This Category Looks Like
Data for this category mainly comes from public building material quotation platforms, home improvement project pricing databases, and industry association-released material guidance prices and construction fee standards. There are two update cadences: building material unit prices update weekly, while construction-related profit margin benchmark values update quarterly. The document structure is a structured table that includes material category, specification model, unit, benchmark price, floating range, and construction process corresponding fee rate. Fields and units follow industry general norms: material units are square meters, linear meters, and pieces; benchmark price units are yuan per corresponding unit; profit margin-related fields are presented as interval values.
Constraints on Multi-turn Dialogue and Prompt Engineering
Weekly updated building material unit prices require regular market refresh triggers during multi-turn dialogue. Prompts must explicitly specify data time ranges to avoid using outdated information. The structured table document structure requires prompts to guide the model to process content by field categories. Multi-turn dialogue must maintain context of the currently viewed material category and construction process to avoid mixing parameters of different specifications. Varied field units require unit validation rules in prompts to prevent the model from mixing different pricing unit logic. Quarterly updated profit margin-related data requires active confirmation of the user's query cycle range during multi-turn dialogue to avoid referencing data across cycles.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Decoration and renovation data includes multiple sets of material, process and cycle information, requiring complete context retention in multi-turn dialogue |
Number of Retrieved Entries | Top 6–8 | This category has many data fields. Too many retrieved entries will exceed the context window limit, while too few will miss key parameters |
Similarity Threshold | 0.75–0.85 | Descriptions of building materials and construction processes have high similarity, requiring filtering of low-match redundant knowledge base content |
maxTokens | 2000–3000 characters | Daily reports require integrating multiple sets of data for comparison. Overly long replies reduce readability, while overly short replies miss key information |
contextWindowKeepStrategy | Retain the last 3 turns per conversation | Users switch query topics during multi-turn dialogue. Retaining too much old context will cause the model to confuse current queries |
knowledgeBaseRefreshInterval | 168 hours | Building material unit prices update weekly, requiring synchronization of latest market data |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material types, data volume and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: Enabling input guidance and configuring a custom knowledge base address results in an error in the debug preview interface. Reason: The custom knowledge base address has not completed the permission configuration required by the platform, or the knowledge base file does not use the structured table format common to this category.
- Phenomenon: Setting
maxTokensto above 3000 results in some responses for multi-material comparison queries being limited to 200 characters. Reason: No long-content reply guidance rule is added in the custom prompt, or the platform's built-in single-turn reply fallback threshold is triggered. - Phenomenon: Real-time generated profit margin data cannot be directly added to the knowledge base during dialogue. Reason: The temporary storage switch for dialogue data is not enabled, or the correct synchronization trigger condition is not selected in the knowledge base management interface.
How to Verify Successful Configuration
- Enter the debug preview interface, enter a query involving multiple decoration material categories, and confirm that the returned content accurately associates with the current conversation topic and does not mix previous query parameters.
- Trigger knowledge base content recall, and confirm that the number of returned results matches the preset recall rules and the matching degree meets the set standards.
- Initiate a query that requires integrating multiple sets of data, and confirm that the actual returned response length matches the preset limit requirements.
- Wait for a complete building material update cycle, and confirm that the latest data in the knowledge base has completed synchronization.
