What Data for This Category Looks Like
Precious metals investment research data primarily comes from official exchanges, industry self-regulatory organizations, and third-party market data service providers. Real-time market data updates at a second-level frequency, including fields such as product quotes, price changes, trading volume, and more. Units mostly use grams and ounces. Regular research reports and industry reports are updated daily, weekly, or monthly. Their document structure includes supply and demand analysis, policy interpretations, inventory data, and fields covering delivery grades, purification costs, cross-border price spreads, and more. Some officially released data includes a unique traceability number.
What Constraints Do These Characteristics Impose on the Citation Sources and Traceability Link
The second-level update frequency of real-time market data requires citation traceability to be bound to a timestamp precise to the second. Otherwise, cited content may experience timeliness deviations. Fields with multiple coexisting units require traceability to retain original unit markings, to avoid misunderstandings from cross-unit citations. Officially released data with attached traceability numbers requires configuring rules to automatically associate official numbers, to ensure the traceability chain is verifiable. Data sources with different update frequencies need classified traceability rule configuration, distinguishing traceability logic between real-time market data and periodic reports. Publishing institution information must also be retained to meet compliance requirements.
How to Configure Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Recall Count | Top 10 entries | Precious metals research report data mostly consists of structured fields. Excessive recall leads to redundant context. 10 entries cover core supply and demand and market information |
Similarity Threshold | 0.75–0.85 | Precious metals market data has strong timeliness. A threshold that is too low introduces irrelevant historical data, while a threshold that is too high may miss latest market trends |
PARSE_FILE_METADATA_ENABLE | Enabled | Official traceability numbers, publishing institutions and other metadata of precious metals documents must be extracted to build the traceability chain |
SOURCE_REFERENCE_TIMESTAMP | Bound to document release time | Real-time market data requires a timestamp precise to the second to ensure cited content timeliness can be verified |
REFERENCE_UNIT_PRESERVE | Retain original units | Multiple units such as grams and ounces exist in precious metals data. Retaining original units avoids citation ambiguity |
MAX_REFERENCE_AGE | 3600 seconds | Real-time market data loses reference value after more than 1 hour. Periodic reports can adjust this parameter based on their update cycle |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Setting
Recall Countto unlimited, resulting in far more returned results than expected. This occurs because recall volume is not restricted based on the characteristics of precious metals structured data, leading to context overload. - Failure to extract official traceability numbers from knowledge base citations, with text extraction components returning empty fields. This occurs because the
PARSE_FILE_METADATA_ENABLEconfiguration is not enabled, and metadata extraction functionality is not activated. - Inconsistent units appearing in cited precious metals market data, such as quotes using both grams and ounces. This occurs because the
REFERENCE_UNIT_PRESERVEconfiguration is not enabled, and original unit markings are not retained.
How to Verify Proper Configuration
- Upload a precious metals real-time market document, and check if the parsed metadata includes official traceability numbers, publishing institutions and a precise timestamp.
- Initiate a knowledge base recall query, and verify that the number of returned results matches the
Recall Countconfiguration value. - Review unit markings in citation results, confirm they match the units of the original document, and no automatic conversion deviations occur.
- Trigger a recall of old market data older than 1 hour, and check if the system filters content exceeding the
MAX_REFERENCE_AGEthreshold.
