Interactive Multi Interest Process Pattern Discovery
This work addresses the need for more flexible and expert-informed process pattern discovery in domains like business process management, though it is incremental as it builds on existing methods by adding interactivity and multi-dimensional goals.
The paper tackles the problem of discovering process patterns that affect process outcomes by introducing an interactive, multi-interest framework, which extracted meaningful patterns validated by experts and achieved prediction performance comparable to or better than single-interest methods without user-defined thresholds.
Process pattern discovery methods (PPDMs) aim at identifying patterns of interest to users. Existing PPDMs typically are unsupervised and focus on a single dimension of interest, such as discovering frequent patterns. We present an interactive multi interest driven framework for process pattern discovery aimed at identifying patterns that are optimal according to a multi-dimensional analysis goal. The proposed approach is iterative and interactive, thus taking experts knowledge into account during the discovery process. The paper focuses on a concrete analysis goal, i.e., deriving process patterns that affect the process outcome. We evaluate the approach on real world event logs in both interactive and fully automated settings. The approach extracted meaningful patterns validated by expert knowledge in the interactive setting. Patterns extracted in the automated settings consistently led to prediction performance comparable to or better than patterns derived considering single interest dimensions without requiring user defined thresholds.
