What data for this category looks like
Yield rate-related data for consumer building materials comes from three main sources: public monitoring ledgers published by the domestic building materials circulation association, shipping settlement records from leading manufacturers, and barcode report data from offline retail terminals. There are three data update rhythms: factory settlement prices update every 7 days, terminal retail prices update daily, and monthly summary data releases before the 5th of each month. Data is stored as structured CSV files, with fixed fields: category code, specification model, factory settlement price, terminal retail price, statistical cycle, data source identifier. Price-related fields use yuan/square meter or yuan/ton as their unit.
Constraints for forms and interactions
The multi-SKU attribute and periodic update features of consumer building materials create multiple constraints for the yield rate and market daily report broadcasting forms and interactions link. Support retrieval by two dimensions: category code and specification model, to avoid confusing large numbers of similar SKUs using only names. Distinguish query entrances for factory price and retail price data, matching their different update cycles, to prevent users from obtaining non-target cross-cycle data for yield rate calculations. Display the current data statistical cycle on the interactive interface, clearly notify users of the data coverage period, to ensure the timeliness and accuracy of daily report broadcasts. Support batch import of multi-category query conditions, adapting to high-frequency scenarios where users query multiple SKUs in a single operation.
How to configure parameters
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
fieldMapping | {"sku_code": "category_code", "spec": "spec_model", "factory_price": "factory_settlement_price", "retail_price": "terminal_retail_price", "stat_date": "statistical_cycle"} | Matches the standard field format of consumer building materials data, preventing field misalignment during knowledge base parsing |
batchQueryMaxSize | 20 entries per call | There are a large number of consumer building material SKUs; setting 20 items per query balances interface response speed and query efficiency |
apiTimeout | 30 seconds | When connecting to third-party building material data platforms, 30 seconds covers the normal response duration of most interfaces |
systemPrompt | Calculate single-product price spread data using construction material factory settlement and terminal retail prices, only use provided structured fields, no extra information | Limits the response scope, aligns with scenario requirements, and avoids generating irrelevant content |
recallTopK | Top 8 entries | Consumer building material SKUs have high similarity; recalling the top 8 results covers core relevant data and avoids redundant results |
iframeAllowOrigins | ["https://your-domain.com"] | Configures valid domains for front-end embedding, ensuring secure cross-domain access for iframe interactions |
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 test on your own samples before finalizing.
Three common configuration mistakes
- Symptom: The front-end iframe can display responses normally, but the back-end interface cannot obtain returned content. Cause:
iframeAllowOriginsis not configured, or the configured domain name does not match the actual front-end domain name, resulting in cross-domain requests being blocked. - Symptom: When the AI identifies procurement information, it mistakenly identifies the packaging specifications of building materials as additional product information. Cause: The system prompt does not clearly limit only identifying specified field content, or the field mapping configuration does not match the actual data format.
- Symptom: The question classification module cannot accurately identify query requests for building material categories. Cause: Classification rules are not built using exclusive terms for consumer building materials, and the classification knowledge base does not cover exclusive fields and scenarios of this category.
How to verify a complete configuration
- Submit a single SKU query request, check whether the returned result only uses the configured field content for responses, with no additional irrelevant information.
- Embed the iframe into a front-end test page, use browser developer tools to check the response status code of cross-domain requests, confirm there are no 403 or cross-domain related errors.
- Import batch SKU query conditions, check whether the number of interface returned results matches the configured
batchQueryMaxSize. - Simulate query requests in different scenarios, check whether the question classification module can accurately classify requests into the consumer building materials yield rate related scenario.
