What the data for this category looks like
Cement yield rate related market data primarily comes from national building material industry monitoring institutions, bulk commodity spot trading platforms, and regional building material wholesale markets. Data updates follow a natural daily cadence, with full updates completed after market close or early the next morning. Individual data documents are grouped by region, and include fields such as region name, cement product grade, quotation type (ex-factory price / market price), unit price value, and statistical reference date. The unit for unit price values is yuan/ton, and there are no additional percentage-based statistical fields. Primary document formats are structured tables or JSON.
Constraints on multi-turn dialogue and prompting
The segmentation of cement market data by region and product grade requires that prompts for multi-turn dialogue must enforce validation of region, grade, and statistical date parameters. Without this validation, accurately matched results cannot be returned. The daily update cadence requires the dialogue system to automatically carry statistical date information from historical context, avoiding repeated requests for the same parameters from users. The unit price measured in yuan/ton requires prompts to explicitly require output to include the unit, preventing the model from returning ambiguous values without units. The structured document format requires prompts to specify field order and output format, to facilitate automatic data integration for downstream daily report generation workflows.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
maxContext | 2000–3000 characters | Covers context for up to 3 rounds of cement market price queries, including key parameters such as region, grade, and date, to avoid context overflow |
system_prompt | Includes mandatory validation for region, cement grade, and statistical date, and requires output to include unit price unit | Cement market data is split by region and grade; mandatory validation reduces invalid queries, and clear unit requirements eliminate result ambiguity |
dialogue_history_max_rounds | 3–5 rounds | Cement market price queries typically require only 2-3 rounds of parameter supplementation; excessive rounds increase context redundancy and reduce response speed |
api_request_timeout | 10 seconds | Matches the typical response duration of building material data source interfaces, preventing request interruptions due to network fluctuations |
output_format | structured list or JSON | Adapts to downstream daily report generation workflows, enabling automatic integration of market data across multiple regions and product grades |
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 individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Repeatedly requesting already provided region or cement grade information during multi-turn dialogue. This occurs when the
dialogue_history_max_roundsparameter is not configured, or themaxContextvalue is set too small, leading to loss of historical context. - Triggering token excess errors when orchestrating multiple large model dialogue nodes. This occurs when the
max_tokenparameter is not individually configured for each dialogue node, and the global context token setting is incorrectly reused. - Receiving a 400 error when attempting to upload cement quality inspection related files via the dialogue interface. This occurs when the
enable_file_uploadconfiguration item is not enabled, or theUPLOAD_FILE_MAX_SIZEvalue is smaller than the actual size of the uploaded file.
How to Verify Proper Configuration
- A test query including a specified region, cement grade, and statistical date is executed, and returned results are verified for complete fields and correct units.
- Two consecutive supplementary parameter dialogues are executed, and the system is verified to automatically reuse key information from historical conversations, without repeating invalid inquiries.
- A test file meeting format requirements is uploaded, and the interface is verified to correctly receive the file and return a successful status code.
- System logs are reviewed to confirm that no context window overflow or truncation occurs for each dialogue request.
