 note = {With the significant increase in accessible resources on World Wide Web, it is important to organize the Web contents effectively in advance. Web directories provide collections of links to lead the users to the sites in the desired category. However, most directories lead the users only to the top pages in the sites. If the users desire to browse the particular pages in the sites, the pages in the sites should be also organized effectively in advance.  This paper proposes a method of automatically constructing the hierarchicalWeb directories consisting of the pages in several sites. In order to construct a hierarchical directory automatically, it is necessary to obtain the hierarchical super-sub relations between the directories. The method finds the Web pages with the super-sub relations as the hyperlink, and replaces the relation by the hierarchical super-sub relation between directories. The method constructs the hierarchical directories by iterating the integration of directories. As a result of the experiment using five web sites, the hierarchical directories consisting of the Web pages in several sites were constructed. Hence, we confirmed the feasibility of the proposed method.},
