Semantic Web applications in- and outside the Semantic Web

This article deals with the question which criteria make up a Semantic Web application. It will be shown that not all applications that make use of Semantic Web technologies actively contribute to the realization of the Semantic Web vision. In order to illustrate this, several exemplary applications are presented. They employ Semantic Web technologies mainly for goals that are rather independent from the Semantic Web vision. Nevertheless, the development of such applications may in the long run even promote the evolution of the Semantic Web, as will be explained in the course of this article. -- Semantic Web ; Semantic Web applications ; Semantic Web technologies ; Semantic Web vision
