What data for this category looks like
Three primary sources supply precious metals-related data: public market data from the Shanghai Gold Exchange, regular financial reports of listed gold mining and smelting enterprises, and daily fixing prices from the London Bullion Market Association. Spot market data updates every 15 minutes. Corporate financial reports release quarterly. Documents include structured reports and market snapshots. Fields cover product purity, trading units, holdings, mined gold output, and more. Unit differences exist between domestic yuan/gram and international US dollars/ounce. Some financial report fields include detailed metrics such as smelting recovery rates and revenue structure.
What constraints these characteristics impose on citation source and traceability
Multi-source unit differences in precious metals data require unified conversion and original unit labeling during traceability. This avoids calculation errors. Differences in update frequencies across data types require separate timestamp markers for static financial report data and dynamic market data. This ensures the timeliness of citations. Differences in field naming across sources exist. For example, LBMA’s "fixing price" corresponds to the domestic "fixing price". Retaining original field names ensures traceability accuracy. Precious metals data has strong detailed attributes. Irrelevant general industry data must be avoided. This imposes higher requirements for recall precision.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
rag_recall_top_k | Top 6–8 results | Precious metals financial reports and market data have scattered fields. Coverage of multi-dimensional data sources is required. Excessive results lead to redundant context. |
rag_similarity_threshold | 0.72–0.78 | Precious metals detailed data has strong correlation. A threshold that is too low introduces irrelevant general data. A threshold that is too high misses accurately matched items. |
source_display_mode | Show original source + data timestamp | Precious metals data has strong timeliness. Clearly labeling acquisition time and channel avoids traceability confusion. |
parse_chunk_size | 800–1200 characters | Precious metals financial reports include structured fields and text descriptions. Chunk length adapts to the integrity of field associations. |
rag_source_timeout | 30 seconds | Precious metals real-time market interfaces have stable response times. Timeout interrupts the traceability data acquisition process. |
The parameter values provided on this page are conventional recommendations used as starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Setting
rag_similarity_thresholdto1still results in irrelevant cited content in responses. Subtle semantic differences exist in field similarity calculations for precious metals data. Setting the threshold to 1 misses some valid matching data. This leads to insufficient recall and the system introduces general text. - A
408 Request Timeouterror returns when calling an external precious metals market interface. A reasonablerag_source_timeoutparameter was not set. The response delay of the precious metals real-time market interface exceeds the default threshold. This causes the traceability process to interrupt. - After importing a Notion-formatted precious metals financial report document into the knowledge base, the original link cannot be displayed during traceability. The corresponding configuration item was not enabled. The original access path of the Notion document was not synchronized.
How to confirm correct configuration
- View the citation module in the response. Confirm that each citation includes the source name, data timestamp, and access path.
- Trigger a financial report analysis request. Check that results return within a reasonable time frame with no timeout errors.
- Adjust the similarity threshold. Observe whether the recalled cited content only includes data related to precious metals detailed categories.
- Import a Notion-formatted precious metals financial report document. Confirm that the complete Notion link path displays in the citation list.
