Dynamically visualizing the relationships between Web pages depending on user's search viewpoints

Opportunities of continuous Web exploration with trial and error have been increased in intellectual creative activities such as research work and PBL. However, it is often difficult to pick up useful pages. In such exploration, information that a user particularly needs and his/her viewpoints changes in accordance with progress of the work and trial and error in it. Therefore, it is important but difficult to understand the relationships between obtained pages and to examine the promising information based on the latest perspectives. We aimed to develop the mechanism for dynamic visualization of the relationships between the pages. This paper mainly describes the outline of our dynamic visualization and methods for extracting the relationships between the pages using focused page of a user as a base point.
