For a mobile robot to act autonomously, it must be able to construct a model of its interaction with the environment. Oates et al. developed an unsu-pervised learning method that produces clusters of robot experiences based on the dynamics of the interaction, rather than on static features. We present a semi-supervised extension of their technique that uses(More)
With the evolution of linked open data sources, question answering regains importance as a way to make data accessible and ex-plorable to the public. The triple structure of RDF-data at the same time seems to predetermine question answering for being devised in its native subject-verb-object form. The devices of natural language, however , often exceed this(More)
In acute ischemic stroke, time from symptom onset to intervention is a decisive prognostic factor. In order to reduce this time, prehospital thrombolysis at the emergency site would be preferable. However, apart from neurological expertise and laboratory investigations a computed tomography (CT) scan is necessary to exclude hemorrhagic stroke prior to(More)
We relate two formerly independent areas: Formal concept analysis and logic of domains. We will establish a correspondene between contextual attribute logic on formal contexts resp. concept lattices and a clausal logic on coherent algebraic cpos. We show how to identify the notion of formal concept in the domain theoretic setting. In particular, we show(More)
