Research Abstract

We have developed new visual interaction techniques to obtain information from a very large and broad collection of data. Our techniques organize and visualize information dynamically, and navigate a user to explore the information space.
First, We have developed a dynamic layout algorithm of documents and keywords and a visual interaction technique based on this algorithm to explore a large collection of documents. This algorithm, "forcedirected dynamic layout algorithm", introduces a spring model to represent the document space and lays out documents and keywords according to these relevance. By introducing dynamic and continuous manipulation of visualized data into the visual clustering, our technique enables a user to explore the information space according to his/her own point of view. We have implemented an experimental visualization system, dalled "DocSpace", based on our technique.
Second, we have developed a visual interface for information mediating systems. There have been proposed "collaborative filtering" techniques that utilize recommendations of others to customize information filters. However, we need not only filtered data but also their relationships in the context of the whole information that has various trends of interests. We have therefore developed an information mediating system that vesualizes information space composed of reviewers and reviewed items. We have implemented the experimental system, "CinemaScape", that mediates movie reviews.
