Introduction

Abstract

The emergence of the Semantic Web has marked another stage in the evolution of the ontology field. According to Berners-Lee, the Semantic Web is an extension of the current Web in which information is given well-defined meaning, better enabling computers and people to work in cooperation. This cooperation can be achieved by using shared knowledge-components. Therefore ontologies have become a key instrument in developing the Semantic Web. They interweave human understanding of symbols with their machine processability.

This workshop addressed the problems of building and applying ontologies in the semantic web as well as the theoretical and practical challenges arising from different applications. We invited and received contributions that enhance the state-of-the-art of creating, managing and using ontologies. The workshop received high quality submissions, which were peer-reviewed by two or three reviewers.
