Semantics to the Bookmarks: A Review of Social Semantic Bookmarking Systems
In: Paschke, Adrian and Weigand, Hans and Behrendt, Wernher and Tochtermann, Klaus and Pellegrini, Tassilo (eds.): 5th International Conference on Semantic Systems (I-SEMANTICS 2009), Proceedings of I-KNOW 09 and I-SEMANTICS 09, Verlag der Technischen Universitt Graz, 2009, pp. 445-454

Abstract In this paper we present a review of systems that follow the novel paradigm of Social Semantic Bookmarking. Social semantic bookmarking allows for the annotation of resources with tags extended by semantic definitions and descriptions that also evolve (collaboratively) within the same system. We analyzed nine different systems that extend social bookmarking in the direction of more semantics; i.e. that enable their users to add semantics to the folksonomy. We studied the systems regarding the realization of the social semantic bookmarking paradigm, the features offered to the users to add semantics, what kind of semantics can be added, and how the system makes use of the semantics. We will present commonalities, main differences and distinctive features, and future trends.

Conceptual Foundations for a Service-oriented Knowledge and Learning Architecture: Supporting Content, Process and Ontology Maturing
In: Schaffert, Sebastian and Tochtermann, Klaus and Pellegrini, Tassilo (eds.): Networked Knowledge - Networked Media: Integrating Knowledge Management, New Media Technologies and Semantic Systems, Springer, 2009

Abstract Effective learning support in organizations requires a flexible and personalized toolset that brings together the individual and the organizational perspective on learning. Such toolsets need a service-oriented infrastructure of reusable knowledge and learning services as an enabler. This contribution focuses on conceptual foundations for such an infrastructure as it is being developed within the MATURE IP and builds on the knowledge maturing process model on the one hand, and the seeding-evolutionary growth-reseeding model on the other hand. These theories are used to derive maturing services, for which initial examples are presented.
