Résumé : The interest for text visualization and visual text analytics has been heavily increasing for the last ten years. The reasons for this development are manifold, but for sure the availability of large amounts of heterogeneous text data (caused by the popularity of online social media) and the adoption of text processing algorithms by the
visualization community are possible explanations. This talk will first provide an overview of text visualization research. In order to classify traditional and state-of-the-art visualization methods, I will present and use an interactive visual survey of text visualization techniques, called TextVis Browser, which is freely available online
(textvis.lnu.se). My talk will then continue with a brief discussion of the most important challenges in text visualization and showcase text visualization research performed by the ISOVIS research group at Linnaeus University, Sweden.

Bio : Andreas Kerren received his PhD degree in Computer Science from Saarland
University, Saarbrücken (Germany). In 2008, he achieved his habilitation (docent competence) from Växjö University (Sweden). Dr. Kerren is currently a Full Professor in Computer Science at the Department of Computer Science and Media Technology, Linnaeus University (Sweden), where he is heading the research group for Information and Software Visualization, called ISOVIS. His main research interests include the areas of Information Visualization, Visual Analytics, and Human-Computer Interaction. He is, among others, editorial board member of the Information Visualization journal, has served as organizer/program chair at various conferences, such as IEEE VISSOFT 2013/2018 or IVAPP 2013-15/2018, and has edited a number of successful books on human-centered visualization.
