We have different openings for Master thesis projects, for example in the area of information management and recommender systems. Contact me by email in case you are interested.
I joined the Department of Artificial Intelligence and Cybersecurity at AAU Klagenfurt as a full professor in 2017. Before that, from 2008 to 2017, I was a full professor of Computer Science at TU Dortmund, Germany.
Appointed a Professor II at University of Bergen, Norway, in March 2021.
My main research theme is related to the application of intelligent system technology to practical problems and the development of methods for building knowledge-intensive software applications.
Generally, my research interest is broad and I have been working on a number of topics over the years, including recommender systems technology, knowledge-based systems development, constraint-based systems, semantic web applications and web mining, special topics in operations research and applications of AI planning as well as on specific software engineering problems in the area of the development and debugging of declarative programs.
Among others, my research has been published in IEEE TKDE, Artificial Intelligence, JAIR, UMUAI, ACM TOIS, ACM TKDD, ACM TIST, ACM TiiS, ACM TMIS, Journal of Web Semantics, Journal of Human Computer Studies, Journal of Systems and Software, IEEE Transactions on Software Engineering, Journal of Retailing, Annals of Operations Research, and in the proceedings of IJCAI, AAAI, RecSys, ICDM, CIKM, WSDM or ISWC.
Between 2003 and 2008, I was a co-founder, technical director and later managing director of a startup company that created an award-winning software tool for the development of interactive sales applications.
I received the Advancement Award by the Province of Carinthia (Förderungspreis des Landes Kärnten) in the area of Technical Sciences in 2006.
In 2018, I was recognized as an Outstanding Reviewer for Springer’s Journal of Information Technology and Tourism, and of the IJCAI-ECAI ’18, ICWSM ’18 and ACM Hypertext ’18 conferences. In 2019, I was a Distinguished Senior PC member for IJCAI ’19, and I received a Best Reviewer Award at ACM UMAP 2021.
I received awards for the best annual paper published in the UMUAI journal in 2015 and in 2020, an ACM Distinguished Paper Award at ICSE 2018, and the ACM Best Full Paper Award at ACM RecSys 2019. In 2021, our research-in-progress paper received the Best Paper Award at the PACIS conference.
