    • On the Contextualization of Event-Activity Mappings 

      Koschmider, Agnes; Mannhardt, Felix; Tobias, Heuser (Journal article; Peer reviewed, 2019)
      Event log files are used as input to any process mining algorithm. A main assumption of process mining is that each event has been assigned to a distinct process activity already. However, such mapping of events to activities ...
    • On the dimension of multivariate spline spaces
