The sequential patterns can be viewed as an extension of the notion of association rules with integrating temporal constraints, which are effective for representing statistical frequency based behaviors between the elements contained in sequence data, that is, the discovered patterns are interesting because they are frequent. However, with considering prior domain knowledge of the data, another reason why the discovered patterns are interesting is because they are unexpected. In this thesis, we investigate the problems in the discovery of unexpected sequences in large databases with respect to prior domain expertise knowledge. We first methodically develop the framework Muse with integrating the approaches to discover the three forms of une...
