Abstract

The mining of a complete set of frequent subgraphs from labeled graph data has been studied extensively Recently, much attention has been given to frequent pattern mining from graph sequences In this paper, we propose a method to improve GTRACE which mines frequent patterns called FTSs (Frequent Transformation Subsequences) from graph sequences Our performance study shows that the proposed method is efficient and scalable for mining both long and large graph sequence patterns, and is some orders of magnitude faster than the conventional method.
