Kyung‐Mi Lee, Keon Myung Lee · Applied Mechanics and Materials · 2012
This paper introduces a new type of problem called the frequent common family subtree mining problem for a collection of leaf-labeled trees and presents some characteristics for the problem. It proposes an algorithm to find frequent common families in trees. To its applicability, the proposed method has been applied to both several synthetic data sets and a real data set.
