The project SESAME uses semantic modeling and reasoning to support home owners and building managers in saving energy and in optimizing their energy costs while maintaining their preferred quality of living. We design a semantic layer for a technical solution that integrates smart metering, building automation and policy-based reasoning in order to offer an(More)
We propose a model to represent closeness between entities within Web communities and social networks/folksonomies conceptually and numerically, and a community dynamics notification algorithm. The proposed models add value to community environments supporting social networking, and are specifically applicable to the community-driven environments, where(More)

So far hardly any literature exists that discusses thesaurus modelling requirements with respect to the following thesaurus-specific application areas: classifying, indexing,(More)
The project SESAME 1 utilizes smart metering, building automation and policy-based reasoning to support home owners and building managers in saving energy and in optimizing their energy costs while maintaining their preferred quality of living. In this paper, we present how user-created policies are being applied to develop a system of least interference(More)
The paper presents statistical findings from an online survey conducted among Semantic Web specialists from science and industry. It provides the reader with a brief overview over current trends and possible future topics from the perspective of research-oriented and application-oriented participants in the fast evolving and dynamic field of social software(More)
