Abstract
The mining of a complete set of frequent subgraphs from labeled graph data has been studied extensively. Furthermore, much attention has recently been paid to frequent pattern mining from graph sequences (dynamic graphs or evolving graphs). In this paper, we define a novel class of subgraph subsequence called an “induced subgraph subsequence” to enable efficient mining of a complete set of frequent patterns from graph sequences containing large graphs and long sequences. We also propose an efficient method to mine frequent patterns, called “FRISSs (Frequent Relevant, and Induced Subgraph Subsequences)”, from graph sequences. The fundamental performance of the method has been evaluated using artificial datasets, and its practicality has been confirmed through experiments using a real-world dataset.
