Towards Trace Variant Explainability

MCML Authors

Abstract

Understanding process variability remains a key challenge in process mining, especially when analyzing trace variants that capture diverse behavioral patterns in modern systems characterized by high data volume and complexity. In this paper, we propose a multiview explanation framework that enables interpretable analysis of trace variants through both global and local explanations. Our approach first encodes traces using multiple views—including activity, transition, case, and event-level information—applying nominal and time-based strategies suited to structural and performance aspects. Then, it introduces a dual-layer explanation mechanism: at the global level, variant representatives are compared to a global behavioral profile to highlight key differentiating features; at the local level, individual traces are contrasted with their assigned representatives to reveal the specific factors driving their inclusion. The framework is compatible with various variant analysis techniques, as long as a representative (e.g., medoid or central node) can be defined. We demonstrate the method’s effectiveness using benchmark event logs and interpretable visualizations, showing how it supports transparency, trust, and diagnostic insight in trace variant analysis.
