Abstract:
A method for finding sequential patterns of attributes in a directed graph includes constructing a directed graph comprising multiple nodes and edges between the nodes. Each of the nodes may be assigned one or more attributes. Similarly, each of the edges may be assigned a weight value which may indicate the probably the edge will be traversed during traversal of the directed graph. The method may further include finding sequences of attributes in the directed graph that have some minimum amount of frequency and/or time support. In performing this step, the frequency support of each individual instance of a sequence of attributes may be calculated by multiplying the weight values along the edge or edges of the instance. A corresponding apparatus and computer program product are also disclosed and claimed herein.
