Enhancing cybersecurity risk assessment using temporal knowledge graph-based explainable decision support system Permalink

Published in Decision Support Systems, 2025

Assessing cybersecurity policies is crucial for organisations to combat evolving cyber threats. The absence of comprehensive datasets has prevented prior studies from analysing cybersecurity policy risks. Past studies also neglected temporal information in policies, and attention-based analyses often lack automated determination of optimal attention units. Furthermore, the absence of interpretability in cybersecurity studies creates a barrier to understanding policy vulnerabilities and developing targeted solutions.

SENE: A novel manifold learning approach for distracted driving analysis with spatio-temporal and driver praxeological features Permalink

Published in Engineering Applications of Artificial Intelligence, 2023

Although many studies have been conducted on distracted driving, the growing number of accidents on roads demands further serious attention. Most real-world distracted driving data are unlabeled and high-dimensional, making analyses complex. There is a lack of proper indices to understand the perilousness of distracted driving, making it difficult to identify roads or neighborhoods with higher risk of accidents. Previous studies focused either on spatio-temporal or praxeological factors separately, but did not consider both together. Furthermore, crisp rule extraction and interpretation are largely missing in the literature.
