What This Category’s Data Looks Like
The data sources for energy metals research reports mainly include three categories: industry reports from securities research institutes, statistical data from industry associations, and public announcements from mining enterprises. Update cycles are divided into three types: daily dynamic price reports, weekly supply and demand tracking reports, and quarterly in-depth analysis reports. Document structure is primarily unstructured text, interspersed with structured tables containing prices, inventories, production capacity, and other metrics. Core fields include metal variety name, transaction price, unit of measurement, release date, and releasing institution. Common units of measurement are industrial standard units such as yuan/ton, USD/pound, and ten thousand tons.
Constraints Imposed on HTTP Interfaces and External Systems by These Characteristics
The structured fields and specialized measurement units of energy metals research reports require interfaces to support precise filtered retrieval by dimensions such as variety and unit. The document structure of long text interspersed with tables requires the interface’s parsing module to adapt to table extraction and long context retention. The multiple update frequency categories of data sources require external systems to support both incremental and full synchronization modes to avoid duplicate or missed data. Additionally, format differences across institutional data sources require interfaces to support a variety of non-standard docx and pdf file formats to ensure parsing consistency.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Energy metals research reports often contain multiple price tables and long sections of supply and demand analysis, requiring sufficient context to associate data dimensions |
recallTopK | Top 8–12 entries | A single research report covers multiple types of information such as variety, price, and policy, requiring sufficient recalled fragments to cover core retrieval needs |
parseDocxTableEnable | Enabled | Energy metals research reports often present structured data such as prices and inventories in tables; enabling this option extracts accurate fields for retrieval |
requestTimeout | 600 seconds | Parsing and retrieving a single long research report takes significant time; extending the timeout prevents request interruptions mid-process |
syncInterval | Every 24 hours | Industry research report updates primarily occur daily and weekly; daily synchronization covers most regular update scenarios |
fileMaxSize | 1000 MB | Large industry research report collections have significant file sizes; relaxing the size limit supports batch synchronization of complete data sources |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Phenomenon: An "file upload not supported" error is returned when calling the HTTP interface, but document upload works normally in the chat interface. Cause: The file upload permission for the API interface is not enabled, or the file parameter transfer format specified in the API documentation is not followed during the call.
- Phenomenon: A format error is returned when calling the knowledge base content interface, but the docx file can be downloaded normally when the link is accessed directly in a browser. Cause: The docx file parsing rules for the interface are not configured, or the correct content type parameter is not specified in the request.
- Phenomenon: No configuration option for the target data source is available in the API call interface, making it impossible to bind the research report data source. Cause: The API access function for external data sources is not enabled in the platform backend, or the data source mapping configuration for the corresponding category is not completed.
How to Verify Successful Configuration
- Initiate a single file upload request, upload a standard energy metals research report docx file, and check whether the parsed results returned by the interface include structured fields such as price and inventory.
- Call the retrieval interface, specify a specific energy metal variety as the search keyword, and check whether the number of returned results matches the configured recall rules.
- Review the response data returned by the interface to confirm that the unit information and releasing institution identifier from the original research report are retained in the returned content.
- Initiate a scheduled synchronization test request, check whether the research reports from the external data source are automatically updated at the configured interval, and confirm there are no missed or duplicate synchronized entries.
