Automated Alignment of Multiple Internet Directories

Directory services are tools for making useful information more accessible, but individual internet directories in directory services are of limited use in nding user-relevant web pages. In this paper, we propose a method for aligning URL information from one internet directory to another. This method can discover an appropriate position in a directory for a web page which is not shown in that directory but shown in another directory. By using this method, one can extend a favorite directory with information on other directory services. Discovery of alignment is based on categorization similarity in the concept hierarchies of the two internet directories. We adopted the \ statistic" method to measure the similarity syntactically. We conducted an experiment using real-world internet directories. The results of this experiment show that the proposed method is promising, i.e., it can classify unknown web pages into appropriate categories within an internet directory.
