What the Data for This Category Looks Like
Energy metals-related financial report data comes from three main sources: public periodic reports of listed companies, monthly/quarterly industry data released by industry associations, and public quotes from commodity exchanges. Update frequencies fall into two categories: listed company financial reports are updated on a fixed quarterly and annual schedule. Industry spot and inventory data is updated weekly or daily. Available document formats include PDF financial reports, web tables, and Excel-format industry data. Documents include two types of fields: general financial fields and category-specific parameters. General fields include revenue, attributable net profit, and net operating cash flow. Category-specific parameters include cathode copper purity indicators, lithium ore grade indicators, and metal inventory levels. Common units are tons and yuan per ton.
Constraints for Citation and Traceability Workflows
Data sources for energy metals financial report analysis span multiple channels, with significant differences in update cycles and formats across sources. Both category-specific and general financial fields are present, so precise traceability identifier differentiation is required. Decentralized data sources require traceability links to cover metadata tags from all sources, including publishing organization, update time, and document version. Different document formats need tailored parsing rules to ensure extracted fields map directly to their source materials. Traceability for category-specific parameters must be tied to exclusive data sources to avoid confusion with general financial data and compromise analysis accuracy. High-frequency updated industry data and low-frequency updated report data require separate traceability time limit configurations to prevent use of outdated cited data.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_top_k | Top 8-12 entries | Energy metals financial reports contain numerous segmented fields, requiring sufficient recall to cover both category-specific and general financial data |
source_trace_enable | Enabled | Each cited passage must be bound to source information to meet industry analysis traceability requirements |
parse_file_timeout | 600 seconds | Parsing large energy metals financial report PDFs takes significant time, requiring adaptation to document scale |
field_matching_rule | Prioritize matching by category-specific fields | Energy metals category-specific parameters must be bound to their corresponding data sources first to avoid confusion |
source_tag_format | [Source Name] + [Publication Time] + [Document Page Number] | Aligns with the traceability reading habits of industry analysts |
rag_chunk_size | 800-1200 characters | Adapts to the paragraph length of segmented fields in energy metals financial reports, avoiding splitting that disrupts field integrity |
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. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: Irrelevant data source citations appear in generated financial report analyses. Cause: The
field_matching_ruleis not configured, leading to confusion between general financial field sources and energy metals-specific field sources. - Phenomenon: A
PARSE_FILE_TIMEOUTerror is triggered when parsing large energy metals financial reports. Cause: Theparse_file_timeoutvalue is set below 600 seconds, failing to adapt to the parsing time required for large PDF documents. - Phenomenon: Citation tags are forcibly included in generated reports, with no option to adjust them as needed. Cause: The optional switch for
source_trace_enableis not configured, or the global traceability configuration is accidentally enabled.
How to Verify Correct Configuration
- Upload a quarterly financial report PDF from an energy metals listed company, and check if parsed fields are automatically associated with corresponding source information.
- Submit a financial report analysis request, and verify that cited passages in the generated content include the source name, publication time, and document page number.
- Adjust the value of
recall_top_kto confirm that the number of recalled data sources matches the current analysis requirements. - Upload an extra-large energy metals financial report document, and confirm that no timeout error is triggered during the parsing process.
