Abstract(in English) | We present a method for discovering knowledge from graph structured data, especially tree structured data. A term tree is a data structure which represents a pattern consisting of variables and tree-like structures. A term tree is more powerful than the standard representation of a first order term. In order to realize an efficient knowledge discovery system from tree structured data, we have given a polynomial time algorithm for deciding whether a term tree and a tree are matched or not. We have implemented the matching algorithm. Experimental results show that the matching algorithm is efficient and useful in knowledge discovery from tree structured data Also we discuss an application of the algorithm to a knowledge discovery system. |
