What the Data for This Category Looks Like
Data for plastics and rubber financing daily reports comes from four main sources: domestic commodity trading platforms, futures exchange warehouse receipt databases, industry association statistics, and customs import and export financing filing data. Data follows a T+1 daily update schedule: full updated data is released the day after trading closes. Each document includes fields such as date, sub-category (e.g., polyethylene, natural rubber), daily financing scale, warehouse receipt pledge volume, financing term, month-over-month change, corresponding spot price reference, and other fields. Uniform units are used: renminbi ten thousand yuan for financing scale, tons for warehouse receipt pledge volume, days for financing term. Some cross-border data sources include auxiliary fields denominated in US dollars.
What Constraints These Characteristics Impose on Citation Sources and Traceability
Mixed multiple data sources require priority rules for the traceability process. This prevents low-reliability data sources from overriding high-value data. The daily update schedule requires verifying the data timestamp range during traceability. Only data sources published within the last 1 day may be cited. This avoids introducing expired historical data. The large number of sub-categories and tightly linked fields require matching three core fields during traceability: sub-category, date, and financing scale. This prevents incorrect citations across categories or batches. The coexistence of multiple units requires automatic unit consistency checks during traceability. This avoids citations with mismatched monetary and weight units.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 8 entries | Plastics and rubber financing daily reports have moderate document length. 8 recalled entries cover core financing data without exceeding the context window |
Similarity threshold | 0.75-0.85 | Financing data fields for sub-categories are clearly defined. A threshold that is too low will introduce irrelevant chemical category data. A threshold that is too high may miss valid sources from the same category |
Data Source Priority Configuration | Futures exchange warehouse receipt data > Local trading platform data > Industry association data | Futures exchange data has higher standardization and stronger traceability reliability. Prioritizing this improves citation accuracy |
Unit Validation Switch | Enabled | Plastics and rubber financing data involves multiple units such as monetary value and weight. Enabling this allows automatic verification of unit consistency in cited content |
Timestamp Matching Threshold | ±1 day | Financing daily reports are updated daily. A 1-day time deviation allowance covers delayed-release data sources |
Field Association Rules | Match three core fields: sub-category, date, financing scale | This accurately associates financing data from the same batch, preventing incorrect citations across documents |
The parameter values provided on this page are general recommendations to serve as a starting point 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 Misconfigurations
- Phenomenon: Knowledge base retrieval returns cited content with red error markers. Cause: The
Unit Validation Switchis not enabled, leading to mismatched units between financing scale and warehouse receipt pledge volume in cited content. The system identifies this as an invalid citation. - Phenomenon: Only the first query in a workflow triggers knowledge base citations, with no citation results for subsequent queries. Cause: Global variable synchronization rules are not configured, and the
datasetidvariable is not passed correctly. Subsequent retrieval nodes cannot associate the corresponding category knowledge base. - Phenomenon: Retrieval results include financing data from non-plastics and rubber categories. Cause: The
Field Association Rulesis not configured, and the sub-category field is not limited. This results in recalled content from other basic chemical categories.
How to Confirm Proper Configuration
- Manually upload a standard plastics and rubber financing daily report document, initiate a retrieval, and check that returned citation content includes core fields such as
融资规模and仓单质押量, with consistent units. - View the retrieval node’s running logs to confirm that the
Timestamp Matching Thresholdis active, and only content from data sources within the last 1 day is returned. - Insert multiple consecutive knowledge base retrieval nodes in a workflow, pass different financing daily report date parameters, and check that each node correctly associates content from the corresponding knowledge base.
- Modify the
Similarity thresholdto 0.9, initiate a retrieval, and check that no recall results are returned. This verifies that the threshold configuration is active.
