Graphs are widely used to model complicated data semantics in many applications. In our paper [8], we
proposed Fast-ON, an efficient algorithm for subgraph isomorphism problem. In this paper, we develop an
efficient algorithm called Fast-ON* that extends Fast-ON to handle two other problems, namely, graph isomorphism problem and graph query processing. Our performance study shows that Fast-ON* outperforms previously proposed algorithms of the two problems with a wide margin.
