Using the IBM Watson cognitive system in educational contexts

In the current paper we describe how Watson Experience Manager (WEM), an industrial Question Answering (QA) tool developed by IBM, has been used in an educational context at the National Technical University of Athens (NTUA). During the postgraduate course on Data Science, three student teams experimented with WEM's QA capabilities on three different topics, namely, Nutrition, Autism and New York sightseeing. We present WEM, the workflow followed by the teams together with qualitative and quantitative experimental evaluations.
