Web-Linkage Viewer: Drawing Links in the Web Based on a Site-Oriented Framework
In recent years, link-based information retrieval methods from the Web are developed, such as HITS and Trawling. Since these methods utilize characteristic graph structures of links in the Web, analyzing the links by drawing them understandably will play an important role in the link-based information retrieval. Moreover, Asano et al.,  have shown that a framework using a site as a unit of information is more natural and useful for link-based information retrieval than the existing framework using a page as a unit. Therefore, we should distinguish links inside a site (called local-links) between links between sites (called global-links) and analyze their own graph structures. However, existing drawing tools, such as Gravis  and H3Viewer, do not distinguish local-links between global-links, and therefore they cannot draw graph structures of these links understandably. In this paper, we propose a new drawing tool, named Web-linkage Viewer, in order to draw graph structures in the Web according to the site-oriented framework.
