What the Data for This Category Looks Like
Data sources for minor metal research reports include professional non-ferrous metal industry databases, industry association public reports, and brokerage special research reports. Update cadences have clear tiers: spot daily reports are updated daily, while special research reports are released on demand per project. Document structure includes four core parts: core data tables, market analysis, supply and demand forecast, and policy impact. Core fields include metal grade proportion, spot quotation, total inventory, and production capacity data. Common units include tons, kilograms, yuan/unit weight, and percentage. Some in-depth research reports are lengthy, with individual pieces reaching hundreds of pages.
Constraints Imposed on Deployment and Upgrade Processes
Data characteristics of minor metal research reports impose multiple constraints on deployment and upgrade processes. First, multi-source data has inconsistent units. For example, spot quotations use both yuan/kilogram and US dollars/ton. Standardized field mapping rules must be configured during deployment to avoid unit confusion in retrieval results. Second, document length varies widely, ranging from hundreds of-word spot daily reports to tens of thousands-word in-depth research reports. Segmentation length parameters must be adjusted to balance context completeness and retrieval efficiency. Third, frequently updated spot data coexists with low-frequency special research reports. Incremental synchronization tasks must be configured during upgrade to distinguish update cadences of different data sources, avoiding excessive resource usage from full synchronization. Fourth, table structures of research reports from different sources vary significantly. Custom parsing templates must be pre-configured to adapt to data extraction from different formats.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Minor metal in-depth research reports often exceed 50,000 characters, requiring sufficient parsing time |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Some individual in-depth research reports can reach hundreds of pages, requiring support for large file uploads |
maxContext | 12000–15000 characters | Balances context completeness of long documents and inference resource usage |
RECALL_TOP_K | Top 8–12 results | The volume of minor metal segmented category data is relatively small, prioritizing highly relevant retrieval results |
SIMILARITY_THRESHOLD | 0.72–0.80 | Filters low-relevance general industry expressions, focusing on minor metal-specific data |
SYNC_INTERVAL | Once daily (spot data), Once weekly (special research reports) | Matches update cadences of different data sources, reducing unnecessary synchronization |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: Connection failure error returned when calling an external parsing tool in a Docker deployment environment, with log showing
connect ECONNREFUSED. Cause: The service address inside the container was not configured as the intranet IP of the host machine or the service address within the container network, and 127.0.0.1 was incorrectly used to point to the container itself. - Issue: Custom inference model failed to load due to incorrect custom request address entered when adding the model. Cause: The port and network mapping rules of the container internal service were not matched, and the host port number was used directly instead of the container internal port.
- Issue: Core fields parsed as empty after uploading research reports. Cause: Custom parsing rules were not configured for the specific table format of minor metal research reports, and the default parsing template failed to recognize non-general field names.
How to Verify Proper Configuration
- Upload a single minor metal in-depth research report with more than 100 pages, confirm that the system does not trigger file size limit or parsing timeout errors.
- Initiate a retrieval targeting minor metal-specific data, verify that the returned results include target fields with unified units.
- Check the scheduled synchronization task logs, confirm that the synchronization rules for spot data and special research reports are executing normally.
- Test retrieval effects with different parameter combinations, adjust to a level that meets business requirements for relevance and retrieval efficiency.
