In this work, we present the design and implementation of a system for proof explanation in the Semantic Web, based on defeasible reasoning. Trust is a vital feature for Semantic Web. If users (humans and agents) are to use and integrate system answers, they must trust them. Thus, systems should be able to explain their actions, sources, and beliefs. Our(More)
We present an integrated platform comprising a set of authoring and management tools for mobile location-aware information systems. The development of the platform was targeted in supporting large-scale systems with very crowded use sessions, at the scale of hundreds of simultaneous visitors, addressing information delivery for exhibits with proximity down(More)
In this work we present the desing and implementation of a new system for proof explanation in the Semantic Web, using defeasible logic. Trust is a vital feature for Semantic Web. If users (humans and agents) are to use and integrate system answers, they must trust them. Thus, systems should be able to explain their actions, sources, and beliefs. Our system(More)
This paper introduces booTable, an interactive coffee table prototype constructed by recycled paper aiming to build upon the paradigm of surface computing, but endeavoring to overcome a number of identified limitations of current design practice. In this respect, the paper first runs through the design requirements, decisions and rationale towards creating(More)
