| Research Abstract |
In this project, we developed several methods which computes distance between tree structured data and gives an approximate matching between them. As a result, we obtained fast approximate algorithms which computes edit distance between ordered/unordered trees, fixed parameter algorithm to compute the proper tree edit distance, fast exact algorithm to compute an optimal tree matching via maximum clique problem, a probabilistic model to measure similarity of trees and a learning algorithm for the model.
