In mathematics and computer science, graph edit distance (GED) is a measure of similarity (or dissimilarity) between two graphs. The concept of graph edit distance was first formalized mathematically by Alberto Sanfeliu and King-Sun Fu in 1983. A major application of graph edit distance is in inexact graph matching, such as error-tolerant pattern recognition in machine learning. The graph edit distance between two graphs is related to the string edit distance between strings. … Webmeasurements. Section 3 proposes the unordered k-adjacent tree, inter-graph node similarity with edit distance which is called as NED in this paper, and the NED in directed graphs. In Section 4, we introduce TED*, our modiﬁed tree edit distance, and its edit operations. Section 5 elaborates the detailed algorithms for computing TED*.
