Recent breakthroughs in process mining research make it possible to discover, analyze, and improve business processes based on event data. More and more events are recorded by a wide variety of systems ranging from embedded systems to enterprise information systems. The growth of event data provides many opportunities for process mining. However, current approaches cannot deal well with heterogeneous processes that change over time while emitting torrents of event data. Process mining is typically done for an isolated well-defined process in steady-state in an offline and centralized fashion. In his talk prof. Wil van der Aalst proposes the notion of process cubes where events and process models are organized using different dimensions. The idea is related to the well-known OLAP (Online Analytical Processing) data cubes and associated operations such as slice, dice, roll-up, and drill-down. However, there are also significant differences because of the process-related nature of event data. For example, process discovery based on events is incomparable to computing the average or sum over a set of values. Prof. Van der Aalst will also relate the process cube notion to distributed process mining techniques where event data are partitioned to improve performance and scalability.
