title = "Aggregating Event Knowledge Graphs for Task Analysis",
abstract = "Aggregation of event data is a key operation in process mining for revealing behavioral features of processes for analysis. It has primarily been studied over sequences of events in event logs. The data model of event knowledge graphs enables new analysis questions requiring new forms of aggregation. We focus on analyzing task executions in event knowledge graphs. We show that existing aggregation operations are inadequate and propose new aggregation operations, formulated as query operators over labeled property graphs. We show on the BPIC{\textquoteright}17 dataset that the new aggregation operations allow gaining new insights into differences in task executions, actor behavior, and work division.",
