Combining Sonification and Visualization for the Analysis of Process Execution Data

Business process execution data is analyzed for different reasons such as process discovery, performance analysis, or anomaly detection. However, visualizations might suffer from a number of limitations. Sonification (the presentation of data using sound) has been proven to successfully enhance visualization in many domains. Although there exist approaches that apply sonification for real-time monitoring of process executions, so far this technique has not been applied to analyze process execution data ex post. We therefore propose a multi-modal system, combining visualization and sonification, for this purpose. The concepts are evaluated by a prototypical ProM plugin as well as based on a use case.
