1 SP-L 2002 Research Notes Web MiPage A Mobile -based Web Page Constructing Framework MiPage Naoki FUKUTA Tadachika OZONO Toramatsu SHINTANI 1 Department of Intelligence and Computer Science, Nagoya Institute of Technology fukuta@ics.nitech.ac.jp, chika@ics.nitech.ac.jp, tora@ics.nitech.ac.jp, keywords: mobile agent, world wide web, logic programming Summary In this paper, we present a programming framework, MiPage, for realizing intelligent WWW applications based on the mobile agent technology. On the framework, an agent is programmed by using hyper text markup language and logic programming language. To realize the framework, we designed a new logic programming environment MiLog, and an agent program compiler MiPage Compiler. The framework enables us to enhance both richness of the services and manageability of the application. 1. Web MiPage 1) Web HTML 2) MiLog[Fukuta 01] 3) HTTP Web WWW 1 WWW [Shintani 01] MiPage
