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.
