Claim 12:
13. The system of claim 10, wherein the plurality of features is captured by:
generating a topological ordering of each graph based on an order of occurrence of a label associated with each node in each graph;
generating a topological sequence of each graph comprising a plurality of levels indicating an order of occurrence of a same node label in the topological sequence;
generating a temporal signature for each graph comprising a series of total passage times between nodes in a union of a plurality of topological sequences;
generating a temporal proximity kernel between a plurality of pairs of temporal signatures;
generating a shortest path kernel by calculating an edge walk similarity on at least one shortest path graph for a plurality of pairs of graphs;
generating a node kernel by comparing node labels of a plurality of pairs of graphs; and
fusing the temporal proximity kernel, the shortest path kernel, and the node kernel.
