Discovering process models from event logs of multi-agent systems using event relations

The structure of a process model directly discovered from an event log of a multi-agent system often does not reflect the behavior of individual agents and their interactions. We suggest analyzing the relations between events in an event log to localize actions executed by different agents and involved in their asynchronous interaction. Then, a process model of a multi-agent system is composed from individual agent models between which we add channels to model the asynchronous message exchange. We consider agent interaction within the acyclic and cyclic behavior of different agents. We develop an algorithm that supports the analysis of event relations between different interacting agents and study its correctness. Experimental results demonstrate the overall improvement in the quality of process models discovered by the proposed approach in comparison to monolithic models discovered directly from event logs of multiagent systems.
