WebJul 27, 2024 · The most representative metric for measuring similarity between two graphs is the graph edit distance. Most of methods for graph search problems use this graph edit distance to measure similarities among graphs. Other most representative measures are to use maximum common subgraphs or graph kernels [42,43] between two graphs. WebIn this thesis, we compare similarity between two trees. A well-studied distance between two ordered labeled trees is the classic tree edit distance ([47,48]). Edit dis-tance measures the similarity between two trees by transforming one tree to another through pointwise edit operations include relabeling, insertion and deletion, one node at a time.
