• A Browsing System for a Database Using Visualization of User Preferences

  The system has the following features: (1) The use of 3D thumbnail objects to represent their contents and properties, (2) The use of some property views and multidimensional scaling (MDS) to lay out the objects in information space, and (3) The use of update mechanism to perform the adaptive visualization to changes in user preferences. In this environment, the user becomes aware that there are information sets which the user seems to be interested in, from objects in information space , and stroll there

• Virtual Library: Yawara

  The main purpose of Yawara is to provide users with a personalized information set accessible through a user friendly interface. The users find useful information with walk-through virtual information space. The system supports that users can browse the virtual information space with an awareness of relation between user features and information features. This paper addresses the following problems on information retrieval with the browsing in the current systems, from a view of realization of the system. The problems are (1) the definition of reader feature is not enough; (2) the reader feature is static; and (3) Complicated visualization. In this paper, we propose a solution based on the reader features such as the personal interest information and reference history, and management mechanism for dynamic reader features on the browsing. The information of readers feature is visualized by the metaphor of a book. We show the usefulness using a prototype system based on our method.
