Abstract: A task support system and method improve an operator's handling of an unknown new event. The task support system and method handle an event that occurred in a management target, in relation to an unknown event, and one or more event types are evaluated as event type candidates. A first event type candidate group having a high confidence score among the evaluated event type candidates is extracted and a first candidate confidence score is calculated from each confidence score of each event type candidate of the first event type candidate group. A first candidate importance is calculated from first importance held by an event type corresponding to each event type candidate belonging to the first event type candidate group and information other than the first importance. A diagram corresponding to each event is represented in a coordinate space by using the first candidate confidence score and the first candidate importance.
