Abstract: Aspects of the present disclosure describe structural event detection from system log messages. More particularly disclosed are computer-implemented methods to mine structural events as directed workflow graphs where nodes of the graphs represent log patterns and edges represent relations among patterns. Advantageously, the structural events are inclusive and correspond to interpretable episodes in the system and methods according to the present disclosure directly model the overall quality of structural events. Through both qualitative and quantitative experiments on real-world datasets, the effectiveness of the disclosed methods are demonstrated.
