Since January 2019, I am a Professor for Natural Language Processing and Data Analytics and member of the interdisciplinary Language and Computation group with the University of Essex, England, UK. Prior to my current position, I was a Associate Professor for Data Science and Predictive Analytics with the University of Stirling, Scotland UK, from August to December 2018. I had a fixed-term Professorship of Knowledge Discovery at Kiel University (W2 level, roughly equivalent to associate professor) and ZBW—Leibniz Information Centre for Economics in Kiel, Germany from January 2014 to July 2018. In Kiel, I was scientific leader of the EU Horizon 2020 project MOVING, enabling young researchers, decision makers, and public administrators to employ and use machine learning and data mining tools to search, organize, and manage large-scale information sources on the web such as scientific publications, videos of research talks, social media, etc. Before joining Kiel University, I was Juniorprofessor (W1 level, roughly equivalent to assistant professor) at the University of Mannheim, and Postdoctoral research associate as well as Juniorprofessor at the University of Koblenz-Landau in Coblenz, Germany. In Coblenz, I was work package leader for the EU FP 7 projects—WeKnowIt and Social Sensor. Previously, I acquired a Marie Skłodowska-Curie Fellowship of the EU for a 1-year research stay at the University of California at Irvine, California.

Ansgar has an excellent research reputation in Text and Graph Mining, specifically in the combination of symbolic and subsymbolic (statistical) methods for data analysis. He has won the Billion Triples Challenge at the International Semantic Web conference in 2008 and 2011. The goal of the Billion Triple Challenge is to demonstrate scalability of semantic technologies. Ansgar is elected speaker at the ACM SIGMM Rising Stars Symposium of the Special Interest Group on Multimedia (SIGMM) of the Association for Computing Machinery (ACM) that was held in October in Amsterdam honoring his 10 years of research in metadata mining and semantics. He published over 150 peer reviewed conference papers and journal articles.
