What the Data for This Category Looks Like
Consumer building materials market data primarily comes from public quotes on domestic bulk commodity building material trading platforms, regional building material dealer reported data, and daily aggregated data from industry associations. Data is updated daily. Full category market data for the current day is aggregated and released in the early morning of the following day. The structure of a single daily report document includes fields such as category name, specification model, origin, region, current listed price, previous day’s benchmark price, and statistical period. Pricing units vary by category: tile, coating, and similar categories use yuan/square meter; pipe materials, waterproof materials, and similar categories use yuan/ton; small accessories use yuan/item.
Constraints Imposed on Model Access and Configuration
Multi-source consumer building materials data has significant format differences, and some data sources include redundant fields. Precise field filtering and mapping rules must be configured during model access to ensure input fields meet task requirements. The daily update release rhythm requires a fixed scheduled pull cycle to avoid data lag or repeated pulls. Variations in pricing units across categories require unit standardization conversion parameters to unify data standards. The statistical period of daily reports is fixed as the natural day, so a data timestamp verification rule must be configured to include only valid data from the corresponding period. A single daily report covers many detailed categories, so a reasonable recall limit must be configured to avoid irrelevant data interfering with the model’s daily report generation logic.
How to Set Configuration Parameters
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
scheduleCron | 0 0 6 * * * | Consumer building material daily reports are typically finalized before 5 a.m. daily; pulling data one hour earlier ensures access to complete, latest data |
fieldMapping | {"category_name": "category", "spec_model": "spec", "current_listed_price": "current_price", "previous_day_base_price": "base_price"} | Standardize field naming for model inputs to support subsequent price comparison and daily report generation logic |
unitConvertRule | {"yuan_per_sqm": 1, "yuan_per_ton": 0.001, "yuan_per_piece": 1} | Convert pricing units across categories to a unified base to eliminate interference from unit differences in model analysis |
maxRecallCount | Top 20 entries | Valid data entries in a single consumer building material daily report typically range from 15 to 25; recalling 20 entries covers most detailed categories |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing overhead for a single consumer building material daily report is low; a 300-second timeout covers delays from bulk pulls and parsing |
similarityThreshold | 0.75 | Filter redundant data with low relevance to the market daily report task, retaining core price and category information |
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. Each scenario requires specific analysis, and testing on local samples is recommended before finalizing settings.
Three Common Misconfiguration Issues
- A 404 status code (no body) is returned during model access testing. The model’s API address or key permissions are not configured correctly, causing requests to fail to reach the target model service.
- When uploading a consumer building material daily report file in simple mode, some files are not automatically parsed by the model. The automatic parsing switch is not enabled, or the configured
UPLOAD_FILE_MAX_SIZEparameter value is smaller than the actual size of the uploaded file. - A market daily report generated in non-tool call mode does not reference real-time web-searched consumer building materials data by the large language model. The
enable_web_searchparameter is not enabled, or the system prompt does not explicitly require the model to call search tools to obtain the latest market information.
How to Confirm Configuration is Complete
- Execute a model access test request, check if the returned response status code matches expected values, and confirm API configuration is correct.
- Upload a standard-format consumer building material daily report test file, verify that parsed fields match the configured
fieldMappingrules. - Manually trigger a scheduled pull task, check if pulled data includes current day’s valid price information and that units have been standardized.
- Enable test mode to generate a single daily report, confirm generated content covers the entry range specified by the configured
maxRecallCountparameter.
