What the Data for This Category Looks Like
Data sources for precious metals research reports include exchange market data APIs, industry association statistical reports, and analysis documents from professional financial institutions. There are two update cadences: spot and futures market data updates daily. Industry research reports are released weekly or monthly. Document structures typically include market snapshot, supply and demand analysis, policy interpretation, and price prediction modules. Fields include product code (e.g. AU9999), transaction price (unit: yuan/gram or USD/ounce), position volume (unit: lots), publishing institution, and publishing time. Some research reports include historical data comparison tables.
Constraints on Citation Source and Traceability
Precious metals data has segmented fields and specific unit requirements. Traceability information must accurately match product codes, trading units, and release times. Otherwise, cited content will be confused. Frequently updated market data requires the knowledge base to refresh regularly. Using outdated data in citations reduces answer accuracy. Research reports focus on a single product category. If irrelevant category keywords are not filtered during recall, irrelevant content from other non-ferrous metal categories will be introduced. This undermines the specificity of traceability. Table data attached to some research reports must retain full field units to make traceability information referenceable.
Configuration Settings
| Configuration Item | Recommended Range | Rationale |
|---|---|---|
similarity threshold | 0.72–0.88 | Precious metals research reports include segmented codes and units. A threshold that is too low will introduce content from other non-ferrous metal categories |
recall count | Top 3–5 entries | Single precious metals research report content is focused. Too many recall results will cause answer redundancy and cluttered traceability information |
maxContext | 8000–12000 characters | Standard single precious metals research reports are mostly 5000–7000 characters long. Full citation content must be retained |
knowledge base auto-refresh cycle | Daily | Spot precious metals market data updates daily. The latest research reports and market information must be synchronized |
citation display fields | Publishing institution, publishing time, data unit | Precious metals data relies on clear units and timestamps. Traceability requires these key pieces of information |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing large-volume research reports takes longer. Timeout truncation must be avoided |
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. Each situation requires individual analysis. Testing on independent samples is recommended before finalizing settings.
Three Common Mistakes
- Phenomenon: Recall results include research reports on other non-ferrous metals such as copper and aluminum. Data units are not displayed in citation fields. Cause: The
similarity thresholdis set below 0.7, and precise matching of precious metal-specific codes and unit keywords is not achieved. - Phenomenon: API call responses do not include any citation sources. Cause: The
enable citation traceabilityconfiguration item is not enabled, or the knowledge base fails to correctly parse the metadata fields of research reports. - Phenomenon: The target research report exists in the knowledge base but cannot be recalled. The number of citations does not meet expectations. Cause: The
recall countis set too low, ormaxContextdoes not cover the full content of the research report, resulting in truncation of key information.
How to Verify Proper Configuration
- Upload a single standard precious metals research report. Check the parsed metadata list to confirm that fields such as publishing institution, publishing time, and data unit are included.
- Enter a query term that includes specific precious metal codes and units. Verify whether the number and matching degree of recall results meet expectations.
- Call the test interface to generate a response. Confirm that the returned result includes complete citation source information.
- Adjust configuration items. Compare recall results under different parameters to confirm that matching accuracy and traceability information meet business requirements.
