Key Tool for Schema Layer Modeling
| Feature | Traditional Static KG | Proposed Dynamic-Temporal KG |
|---|---|---|
| Temporal Data Handling | Limited (static representation of facts) | Excellent (integrates time layer, speed series) |
| Environmental Understanding | Superficial, lacks dynamic context | Holistic, captures real-time changes & trends |
| Decision Reliability | Lower, based on fixed or outdated data | Higher, context-aware decisions with dynamic input |
| Update Frequency | Low (gradual changes, not real-time) | High (continuously updated with sensor data) |

Case Study: Decision Accuracy Improvement in Obstacle Avoidance
A total of 140 simulation experiments were conducted on a real vehicle platform (FAW Jiefang unmanned light truck) to compare the effectiveness of static-only vs. dynamic-static knowledge graph systems in obstacle decision making.
- Traditional Static KG Accuracy: 0.80 (112/140 successful decisions)
- Proposed Dynamic-Static KG Accuracy: 0.96 (135/140 successful decisions)
This demonstrates a significant 16% improvement in decision precision, leading to enhanced safety and reliability for unmanned vehicles navigating complex environments.
