What the data for this category looks like
Coking coal financing daily report data sources include domestic main producing area spot trade reporting systems, Dalian Commodity Exchange coking coal futures warehouse receipt financing interfaces, and port pledge supervision ledgers. Full data for the previous trading day is synchronized every early morning. Documents use a structured table format. Core fields include coking coal grade, origin, financing entity, pledge quantity (unit: tons), financing amount (unit: ten thousand yuan), registration date, delivery warehouse, and pledge status. The number of entries per daily report fluctuates with market activity, with no fixed upper limit.
What constraints these characteristics impose on source reference and traceability
Multi-source heterogeneous data sources require traceability systems to bind corresponding data source identifiers to individual fields, to avoid confusion between fields with identical names across different systems. The daily update schedule requires traceability information to include the data's registration date as a version identifier, preventing traceability errors across daily datasets. Exclusive fields for the coking coal category (such as grade and origin) require traceability to bind category identifiers, ensuring referenced content only links to coking coal financing data. Structured table format supports cell-level traceability, but field-to-source mapping must be configured to accurately locate the original source of each data entry. Traceability for sensitive data such as financing amount and pledge quantity requires simultaneous disclosure of the data's disclosure level, to comply with industry data usage specifications.
How to set the configuration
| Configuration Item | Recommended Value | Basis for This Selection |
|---|---|---|
enable_source_reference | true | Coking coal financing daily reports include sensitive information such as financing entities and amounts. Source display must be enforced to meet data disclosure requirements |
recall_count | Top 6 | Core data entries per single answer for coking coal financing daily reports are moderate. Too many recalls cause redundant references, while too few fail to cover core associated data |
reference_field_mapping | {"Pledged Quantity": "DCE Warehouse Receipt Interface", "Financing Limit": "Spot Trade Reporting System", "Registration Date": "Supervision Reporting Ledger"} | Coking coal financing daily report data comes from multi-source heterogeneous systems. Binding corresponding source identifiers to fields ensures accurate traceability |
reference_timestamp_field | 登记日期 | Daily updated report data uses the registration date field to distinguish daily data versions, preventing traceability confusion across daily datasets |
similarity_threshold | 0.75 | The coking coal category has high distinctiveness. Setting the threshold to 0.75 filters irrelevant recall results and retains accurate source associations |
reference_unique_id_field | Pledge Number | Financing data requires a unique pledge number to achieve accurate traceability, avoiding confusion between data with identical names but different entities |
The parameter values provided on this page are all conventional recommendations used to determine starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Red error prompts are displayed in the interface, and reference content is empty. Cause: The
reference_unique_id_fieldparameter is not configured, or the bound field does not exist in the imported coking coal financing daily report data. A unique traceability identifier cannot be generated. - Only the first workflow node displays knowledge base references, and subsequent nodes have no references. Cause: The
enable_source_referenceconfiguration is not enabled in subsequent workflow nodes, and the reference switch is only enabled in the initial node. - Reference content includes financing data from non-coking coal categories. Cause: The
reference_field_mappingdoes not bind category filtering fields, or thesimilarity_thresholdis set too low, recalling similar data from unrelated categories.
How to confirm the configuration is correct
- Upload a single test coking coal financing daily report file marked with
Pledge Numberand登记日期, initiate a query, and check the reference module in the answer to confirm that each reference carries the corresponding source identifier and unique number. - Adjust the
recall_countparameter toTop 3andTop 10, verify whether the number of returned references matches the configured value. - Modify the
登记日期field in the test data to a non-current date, check whether the timestamp in the traceability information is synchronously updated to the modified date. - Import financing daily report data mixed with other coal categories, verify whether the system filters reference content from non-coking coal categories, or triggers an exception prompt.
