What the Data for This Category Looks Like
Logistics intelligent due diligence report data sources include logistics waybill systems, warehouse management systems, GPS track terminals, and import and export customs declarations. Waybill data is synced in real time. Warehouse data is updated daily per batch. GPS track data refreshes every 5 minutes. Single due diligence reports use a standardized structure, including fields such as waybill number, sender and receiver subject information, transportation track nodes, timeliness statistics, expense details, and compliance qualification attachments. Field units include kilograms, hours, yuan, cubic meters, and other standard units.
What Constraints These Characteristics Impose on Reference Sources and Traceability
Dispersed multi-source data requires traceability links to associate documents from multiple different systems. Field mapping rules must be configured to match field names across heterogeneous data sources, to prevent traceability from pointing to incorrect data sources. Real-time or high-frequency updated track data requires traceability to limit valid time ranges, to avoid recalling expired track nodes that fail to meet reference timeliness requirements. The multi-field document structure requires traceability to accurately match core business fields, to prevent irrelevant content from being mixed into traceability references and impacting due diligence conclusions. Some compliance attachments must be separately marked with their traceability sources, to meet industry regulatory traceability disclosure requirements.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity_threshold | 0.70–0.80 | Logistics business fields have approximate matching scenarios. This interval filters low-correlation non-target data |
recall_top_k | Top 8 entries | Single logistics due diligence reports involve data from multiple links including transportation, warehousing, and customs declaration. Sufficient associated documents must be recalled |
source_field_whitelist | Calibrated via actual testing | Field naming varies across different logistics data sources. Only core fields required for due diligence reports must be limited for recall |
max_recall_time_range | 7 days | The valid traceability cycle for logistics waybills is typically 7 days. This avoids recalling historical data outside the business scope |
rerank_top_k | Top 3 entries | Core traceability nodes for logistics due diligence are concentrated in three links: waybills, tracks, and customs declarations. Re-ranking focuses results on core references |
trace_enable | Enabled | Due diligence in the logistics industry must meet compliance traceability requirements. Enabling this displays complete source information in responses |
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
- Symptom: Setting
similarity_thresholdto 1.0 still returns non-matching content in traceability references. Cause: Logistics data has field aliases or approximate matches. A strict threshold of 1.0 cannot cover post-mapping field matching scenarios. - Symptom:
408 Request Timeouterrors appear in traceability logs. Cause:max_recall_time_rangeis not configured. A large volume of historical data outside the valid cycle is recalled, causing request timeouts. - Symptom: Irrelevant warehouse inventory field content appears in traceability results. Cause:
source_field_whitelistis not configured. Non-core field data not required for due diligence reports is recalled.
How to Verify Correct Configuration
- The application’s traceability settings page may be accessed, and
trace_enableconfirmed as enabled. - A test logistics waybill document is uploaded, a due diligence query initiated, and traceability references in the response verified to include field information from the corresponding document.
similarity_thresholdis adjusted to the preset business threshold, and the number of returned traceability references confirmed to match expectations.- Application logs are reviewed, and each traceability reference confirmed to include the correct data source identifier and timestamp.
