About me
I am a professor at the University of Würzburg and the head of the data science chair (former DMIR group) and the founding spokesman of the Center for Artificial Intelligence and Data Science. Prior, I was a senior researcher at the University of Kassel. I started my research at the AIFB Institute at the University of Karlsruhe where I was working on text mining, ontology learning and semantic web related topics. My previous work also involved working at the KDE group of the University of Kassel on topics like data mining, semantic web mining and social media analysis. For a couple of years I've been a member of the L3S Research Center located in Hannover.
Research interests
In general, my current research focus is on data science (formerly known as data mining), text mining and semantic web.
Meanwhile, for many years I have followed the idea to combine the processing of natural language with the explicitly represented knowledge known today as knowledge graphs. This naturally leads to research on a combination of Text Mining and NLP methods like representation learning, information extraction, metric learning and ontology learning with research on Semantic Web, or Web Science. To reach these goals, I use and adopt NLP, machine learning and data mining methods. Beside that, I also work on Sentiment Analysis, genre classification and quotation detection. I have applied these methods on historic literature, but also on Social Media data, most recently on chat messages from Twitch.tv.
Other areas I’m interested in and working on are ranking, recommendation and behavior analysis methods. Additionally, my research interests include Anomaly Detection and the analysis of Time Series mostly on the web but recently also on ERP and environmental data, for example modeling states of bee colonies by analyzing sensor data obtained from smart beehives. Since many of these problems can be approached by black box machine learning and deep learning methods, another research area of mine is on explainable AI, to gather insights and understand the models.
To demonstrate my results, my group is working on different application systems: BibSonomy, Everyaware and We4Bee.
