and at the Karlsruhe Institute of Technology, Ger-many. He is the director of the International Center for Advanced Communication Technologies, a joint center at eight international research institutions worldwide. The Center develops multimodal and multilingual human communication technologies that attempt to improve human-human and human-machine(More)
— In this contribution, we look at technology transfer in robotics. Generally, there is a delay between a science-push and a market-pull. In order of finding means to decrease this lag, we are going to look at the causes of this effect and at the means for improving technology transfer. For this purpose, we use a variety of data sources which shed light on(More)
The present contribution investigates the construction of dialogue structure for the use in human-machine interaction especially for robotic systems and embodied conversational agents. We are going to present a methodology and findings of a pilot study for the design of task-specific dialogues. Specifically, we investigated effects of dialogue complexity on(More)
— Many applications in the fields of Service Robotics and Industrial Human-Robot Collaboration, require interaction with a human in a potentially unstructured environment. In many cases, a natural language interface can be helpful, but it requires powerful means of knowledge representation and processing, e.g., using ontologies and reasoning. In this paper(More)
Similarity is a core notion that is used in psychology and two branches of linguistics: theoretical and computational. The similarity datasets that come from the two fields differ in design: psychological datasets are focused around a certain topic such as fruit names, while linguistic datasets contain words from various categories. The later makes humans(More)
— In this paper, we present an integrated approach to knowledge representation for cognitive robots. We combine knowledge about robot tasks, interaction objects including their geometric shapes, the environment, and natural language in a common ontological description. This description is based on the Web Ontology Language (OWL) and allows to automatically(More)
— In this contribution the authors examine robotics research itself. We look at the data which the European funded ECHORD project (European Clearing House for Open Robotics Development) generated. The project began in January 2009 with the ambitious goal of bringing together European robotics manufacturers with the European research institutions and it(More)
