Abstract:

The relationship between tree edit distance and maximum common
subtrees is established, showing that a tree edit distance constrained
by insertion and deletions on leaves only and by a simple condition on
the cost of the tree edit operations, corresponds to a maximum commonsubtree isomorphism, allowing thus the use of known tree edit distance algorithms to solve the maximum common subtree problem, and viceversa. Further, a tree distance based on the size of a maximum common subtree is introduced. |
