Research Abstract |
In this research, the following tree pattern matching problem is considered : Given two unordered labeled trees P and T, the problem is to find out all occurrences of P in T. Here P and T are called a pattern tree and a data tree, respectively. We developed efficient algorithms for the tree pattern matching problem by taking advantage of bit-parallelism on a string matching problem.
