What this category's data looks like
Data for energy metals financing daily reports comes from domestic commodity spot trading platforms, public non-ferrous metal industry monitoring databases, and exchange listed trading data. Full previous trading day data is updated each early morning. Each document includes fields such as product identifier, daily financing scale, financing channel type, trading market affiliation, and data release time. Financing scale is measured in ten thousand RMB. Release time uses standard date formatting. Core information for each single entry is concentrated, with no redundant nested content.
Constraints imposed on traceability by these characteristics
Daily single-product entry requirements mandate that traceability links bind product identifiers and release times, to prevent mixing cross-day or cross-product data. Multi-source data collection requires independent traceability identifiers for each channel, to clearly distinguish original data acquisition paths when outputting content. Standardized fields and units require traceability links to verify data field completeness and unit consistency, to avoid traceability deviations caused by unit conversion. Single document entry density requires precise matching rules during recall, to only retrieve single or a small number of entries directly related to the current query, and prevent redundant data from being included in traceability content.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_count | Top 3 entries | Single-product entries in energy metals financing daily reports are clearly structured. Only the most relevant single day's data needs to be recalled; excessive recall causes redundant traceability information |
similarity_threshold | 0.85–0.90 | Precise matching of product names and release date keywords is required. A threshold that is too low may recall non-target products or non-day data, while a threshold that is too high may fail to retrieve valid compliant data |
traceability_binding_fields | data_source, publish_time | Energy metals financing daily reports require clear distinction between data sources and release times. Binding these two fields ensures uniqueness and timeliness of traceability information |
unit_verification_switch | Enabled | The financing scale field uniformly uses ten thousand RMB as the unit. Enabling verification avoids traceability deviations caused by unit conversion |
matching_mode | Exact matching | Strict matching of product names and release dates is required. Fuzzy matching easily introduces invalid cross-day or cross-product data |
parse_chunk_size | 800–1200 characters | Single financing daily report entries have moderate length. This segment length preserves complete product and data information to facilitate traceability association |
The parameter values provided on this page are common recommended 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 mistakes
- Phenomenon: Cross-day non-target product data appears in exported traceability information. Cause:
matching_modeis not configured for exact matching, orsimilarity_thresholdis set below 0.80, leading to fuzzy recall of irrelevant data. - Phenomenon: Unable to select intermediate values for
recall_count, only fixed values of 100 or 900 are available. Cause: Custom recall count permission is not enabled in system configuration. - Phenomenon: A large amount of irrelevant citation content is still output after setting
similarity_thresholdto 1. Cause: Exact matching rules formatching_modeare not enabled, only similarity threshold is relied on for recall, leading to retrieval of semantically similar but non-target entries.
How to confirm successful configuration
- Retrieve system recall logs, verify that recalled data only includes energy metal products and same-day data corresponding to the current query.
- Review traceability annotations in exported content, confirm that each citation includes clear source and release time information.
- Test queries for different product categories and dates, confirm that only financing daily report entries matching the query conditions are returned.
- Check field completeness of cited content, confirm that all necessary product and scale information is fully retained.
