Event Modeling and Mining: Towards Explainable Events with a Plank Road

Recently, research on event management has redrawn much attention and made great progress. As the core tasks of event management, event modeling and mining are essential for accessing and utilizing events effectively. In this talk, we provide a detailed review of event modeling and event mining. Based on a general definition, different characteristics of events are described, along with the associated challenges. Then, we define four forms of events in order to better classify currently available but somewhat confusing event types; we also compare different event representation and relationship analysis techniques used for different forms of events. We present Event Cube as an example event model which, devised to accommodate multi-sourced event discovery and multi-dimensional analysis of events, represents a big step forward towards explainable events. Finally, we discuss several pending issues and application-specific challenges which also shed light on future research directions.
