Abstract
The goal of this tutorial is to present important theoretical and practical effects of the growing Semantic Web on development of new Web-based educational technology and e-learning applications.
During the tutorial, the attendees are supposed to learn about all the important concepts and topics related to the Semantic Web. They will also see a number of practical e-learning examples, systems, and excerpts from practical projects, all illustrating the topics covered. Finally, they will work interactively with the tutorial presenter on at least one practical example of developing an e-learning-related content for the Semantic Web.

Context
The Semantic Web is the next-generation Web that will enable automatic knowledge processing over the Internet, using intelligent services such as search agents, information brokers, and information filters. It will have tremendous impact on Web-based teaching and learning technologies. The Semantic Web can help establish semantic interoperability between different educational applications on the Web.

Objectives
The goal of this tutorial is to present important theoretical and practical issues of the evolving Semantic Web and to show its effects on development of new Web-based educational technology.

Contents
The tutorial starts with a brief introduction to the basic concepts and ideas of ontologies, knowledge sharing on the Web, and intelligent agents. Then it discusses extensively the models, languages and tools for establishing semantic interoperability on the Web. A number of existing educational software tools, applications, systems and development environments are then analyzed in order to show how the basic ideas change the way we develop educational applications in practice. Specifically, the topics covered are:
• The Semantic Web languages and e-learning
• The Semantic Web services and e-learning
• ontologies in e-learning systems
• integration of agent technology and ontologies in e-learning systems
• selected examples, languages, systems, and ongoing projects
  - tools for creating Semantic Web contents
  - existing ontologies for educational systems
  - task ontology
  - student model ontology
  - ontology-aware authoring tools

During the tutorial, the attendees are supposed to work interactively with the tutorial presenter on at least one practical example of developing an e-learning-related ontology, using appropriate Semantic Web software tools.

Duration of the tutorial
3 hours (half day) or 6 hours (full day).

Intended audience
Developers of Web-based systems, developers of e-learning systems, managers of R&D institutions, students, practitioners, researchers, and other professionals in the broad fields of educational systems and Internet applications.

Prior knowledge required
Only general and vague knowledge of basic concepts in the area of educational systems, as well as some basic ideas of distributed systems design and Internet technology.

Vladan Devedžic is both an active researcher and practitioner in the field of intelligent systems. His major long-term professional goal is a continuous effort to bring close together the ideas from the broad fields of intelligent systems and software engineering. In that sense, his current efforts and research interests are oriented towards practical engineering aspects of developing intelligent systems on the Web. He has written more than 160 papers (24 of them have been published in internationally recognized journals by publishers such as ACM, IEEE, Pergamon Press, etc.), three books on intelligent systems, and several chapters in books on intelligent systems and software engineering edited by distinguished scientists. He has also developed several practical intelligent systems and tools, and actively participates as a consultant to several ongoing projects in industry.
