Abstract
Despite a rapid growth of the social interest in information and related technologies, Japan falls far behind countries in constructing the social information infurastructure such as databases. Vast majyority of objects with educational, academic, and/or cultural importance are left unexplored. This study aims to establish a basis for the analysis and modeling of informatian conveyed in these previously unexplored multidsciplinary objects, and to systematically transform it into a social information resource. We demonstrate the feasibility of systematic modeling of these objects. Our approach here is based on the modeling of information activity as a communication activity, and objects concerned as the media for this activity, thereby revealing the characteristics of interdisciplinary information activities.
