Abstract
Decision Support for Internet Users, called DSIU, is an area of research, we proposed, for decision support systems using two technologies: automated knowledge acquisition from information on the Internet and automated reasoning about the acquired knowledge. This paper describes our research progress and a new research on mathematical models for designing decision support systems in DSIU with respect to realizing the systems and giving contributions to society in the near future. The research progress is described in terms of four automated technologies: (1) judging relevance between words from their meaning, (2) acquiring knowledge from text, (3) handling incomplete and uncertain knowledge, (4) gathering Web-pages using layers of Web-sites, and of two confirmations of the technologies: (5) making check on knowledge in various types of Web-pages and (6) developing prototype systems. The research on mathematical models is described in terms of modeling decision making processes
where the knowledge for the decision is constructed automatically from information on the Internet. This paper also describes a new challenge
in terms of building an online shopping mall using some technologies in DSIU.
