The DARS lab performs cutting-edge research in methods (e.g., AI methods to predict user behavior) and applications (e.g., intelligent user interfaces) in the context of behavioral data analytics and recommender systems. We closely collaborate with both academic and industrial partners in Norway, the EU, and beyond, contributing to Norway's national research initiative on Artificial Intelligence (AI), as well as to current AI-related research challenges in the Norwegian industry sectors. Current main research application areas of the lab include: media, finance, energy, and health. The lab is a spin-out of the Intelligent Information Systems (I2S) group at the Department of Information Science and Media Studies at the University of Bergen. The lab collaborates closely with the Centre for Data Science (CEDAS) at the University of Bergen, the Norwegian Artificial Intelligence Research Consortium (NORA), and conducts research in collaboration with a network of renowned national and international scholars in the context of behavioral data analytics and recommender systems. Outputs of the lab are published in leading conferences and journals in the field of computer & information science and interdisciplinary venues such as: NATURE Sustainability, PlosOne, JASIST, EPJ Data Science, UMUAI, WWW, ICWSM, ACM IUI, ACM UMAP, ACM SIGIR, and ACM RecSys. The core lab members have won several Best Paper/Poster Awards and Nominations, including, the Best Paper Award Honorable Mention at WWW'17. The core team is involved in the co-organization of leading conferences in their fields of research such as ACM RecSys, ACM UMAP or ACM IUI and teaches tech-related courses such as Information Systems, Advanced Programming in Python or Recommender Systems at the University of Bergen.

He published over 100 scientific articles in top-notch venues, such as NATURE Sustainability, PlosOne, JASIST, EPJ Data Science, UMUAI, WWW, ICWSM or ACM SIGIR. He is the winner of several Best Paper/Poster Awards and Nominations, including, the Best Paper Award Honorable Mention at WWW'17.
Mehdi Elahi is an associate professor at the University of Bergen (Norway). He received his M.Sc. degree in Electrical Engineering (Sweden) in 2010, and his Ph.D. degree in Computer Science (Italy) in 2014. Over the last 3 years, he has served as an assistant professor at the Free University of Bozen-Bolzano (Italy), where he has researched various aspects of recommender systems. He has (co-)authored more than 60 peer-reviewed publications in AI, RS, and HCI-related conferences and journals. Moreover, he has co-applied for a US-patent, and has co-authored several EU research proposals. On top of that, he has been awarded a number of industry and academic research grants, e.g., by Amazon and the Polytechnic University of Milan. He has been actively involved in the research and development of up-and-running mobile recommender systems for the food (ChefPad) and tourism domains (South Tyrol Suggests). He has provided various types of community services, such as co-organizing the ACM 2017 RecSys challenge (organized by XING), and has acted as an advisor to the 2018 RecSys challenge (organized by Spotify).
Alain Starke (1990) is a visiting PostDoc at the DARS lab until August 2020. He graduated cum laude at the Eindhoven University of Technology from the master's program Innovation Sciences in 2014. While writing his master's thesis, he landed a 'Research Talent' grant from the Netherlands Organization for Scientific Research (NWO) to pursue a PhD on energy recommender systems at the Human Technology Interaction group, supervised by dr.ir. Martijn Willemsen & prof.dr. Chris Snijders. Last February, he was awarded a ‘Niels Stensen Fellowship’ to fund one year of postdoctoral research on RecSys in behavioral change domains. As of September 2019, Alain has joined the DARS lab to work on psychologically-aware recommender systems in the food and news domains.
Arngeir Berge is a PhD student at the DARS lab. After obtaining his MSc at InfoMedia@UiB, he worked two years as an assist.prof. of ICT in Learning in Volda University College, before proceeding to working with e-learning, technology and multimedia in the health area. He currently works with NORCE, the Norwegian Research Centre on the project “RE-AIMED: Readjusted responses by use of AI in medical calls”, where DARS is a WP leader. In his PhD project, he studies intelligent user interfaces of recommender systems that offer decision support to medical call centre operators.
Peter Brusilovsky is a professor of Information science and Intelligent Systems (Artificial intelligence) at the University of Pittsburgh.
