At the present time, several shortcomings prevent the more effective use and more intense application of web information systems. Recent developments that are subsumed by the term Semantic Web aim to solve these problems. The inherent idea behind these approaches is the annotation of data with metadata, in order to enhance automated processing and the use of ontologies to describe data semantically. However, the emergence of the Semantic Web raises new issues (e.g. significantly higher complexity) for web information system engineers. From an information system engineering perspective, conceptual modeling is an approach for dealing with high complexity and diversified project teams. On the one hand, conceptual models facilitate the (semi)automated generation of information systems. On the other, they foster communication between project team members and provide a sound basis for information system development. In this paper, we present an approach to modeling semantic navigation struc...
