A survey on tree edit distance and related problems
We survey the problem of comparing labeled trees based on simple local operations of deleting, inserting, and relabeling nodes. These operations lead to the tree edit distance, alignment distance, and inclusion problem. For each problem we review the results available and present, in detail, one or more of the central algorithms for solving the problem. keywords tree matching, edit distance
متن کاملTree Edit Distance Problems: Algorithms and Applications to Bioinformatics
Tree structured data often appear in bioinformatics. For example, glycans, RNA secondary structures and phylogenetic trees usually have tree structures. Comparison of trees is one of fundamental tasks in analysis of these data. Various distance measures have been proposed and utilized for comparison of trees, among which extensive studies have been done on tree edit distance. In this paper, we ...

متن کاملTree edit distance with gaps
The purpose of this paper is to study the definition of edit distances with convex gap weights for trees. In the special case of strings, this problem has yield to the definition of classical solutions: Galil and Giancarlo produced in [2] an algorithm in O(n log(n)), for example. For trees, standart edit distance algorithms – [7] or more recently [4] with a O(n log(n))) solution – are concerned...
متن کاملLearning Stochastic Tree Edit Distance
Trees provide a suited structural representation to deal with complex tasks such as web information extraction, RNA secondary structure prediction, or conversion of tree structured documents. In this context, many applications require the calculation of similarities between tree pairs. The most studied distance is likely the tree edit distance (ED) for which improvements in terms of complexity ...
