Knowledge Graph Optimization
This section explores methods to optimize MINDWALC for knowledge graphs structured with distinct background and instance knowledge components. Key insights include the benefits of Relation-Tail Merging (RTM) in reducing graph complexity and improving feature meaningfulness, particularly in cases where relationships are crucial for classification.
Walking Strategies
We investigate new walking strategies, including flexible walking depths and combined approaches, to enhance MINDWALC's ability to detect similarities between node instances. The effectiveness of these strategies is analyzed across different knowledge graph topologies, from property-based to hierarchical structures.
Medical Diagnostics
The application of optimized MINDWALC in a simulated clinical setting for prostate adenocarcinoma diagnosis is evaluated. This highlights the algorithm's potential to generate human-interpretable decision trees that leverage background knowledge to compensate for incomplete instance data, a common challenge in real-world medical practice.
Case Study: MINDWALC in Medical Diagnostics
Challenge: Pathologists face increasing complexity in diagnosing diseases, requiring continuous knowledge updates and standardized decision-making processes. Existing expert systems often lack adaptability and interpretability for advanced cases.
Solution: MINDWALC, enhanced with flexible walking depths and relation-tail merging, was applied to a synthetic knowledge graph for prostate adenocarcinoma diagnosis. This allowed the system to learn interpretable decision trees from the background knowledge, even with incomplete instance data.
Result: Our optimizations significantly improved classification performance on hierarchical, tree-like structured graphs, demonstrating MINDWALC's ability to utilize background knowledge to compensate for missing instance data. The generated decision trees offered human-comprehensible insights into diagnostic pathways, enabling clearer decision-making in a simulated clinical context.
