Abstract. Recent developments in Web technologies and using AI techniques to support efforts in making the Web more intelligent and provide higher-level services to its users have opened the door to building the Semantic Web. That fact has a number of important implications for Web-based education, since Web-based education has become a very important branch of educational technology. Classroom independence and platform independence of Web-based education, availability of authoring tools for developing Web-based courseware, cheap and efficient storage and distribution of course materials, hyperlinks to suggested readings, digital libraries, and other sources of references relevant for the course are but a few of a number of clear advantages of Web-based education. However, there are several challenges in improving Web-based education, such as providing for more adaptivity and intelligence. Developments in the Semantic Web, while contributing to the solution to these problems, also raise new issues that must be considered if we are to progress. This paper surveys the basics of the Semantic Web and discusses its importance in future Web-based educational applications.
INTRODUCTION
One of the hottest R&D topics in recent years in the AI community, as well as in the Internet community, is the Semantic Web. It is about making the Web more understandable by machines (Heflin & Hendler, 2001). It is also about building an appropriate infrastructure for intelligent agents to run around the Web performing complex actions for their users (Hendler, 2001). In order to do that, agents must retrieve and manipulate pertinent information, which requires seamless agent integration with the Web and taking full advantage of the existing infrastructure (such as message sending, security, authentication, directory services, and application service frameworks) (Scott Cost et al., 2002). Furthermore, Semantic Web is about explicitly declaring the knowledge embedded in many Web-based applications, integrating information in an intelligent way, providing semantic-based access to the Internet, and extracting information from texts (Gómez-Pérez & Corcho, 2002).
