Areas of our research comprise these interests:

  • User-centric and personalized information retrieval,
  • NeuroIS – study of neuropsychological aspects of IR  using advanced techniques of neuroimaging towards improving design of user-centric systems,
  • Adaptive information retrieval,
  • Implicit feedback-based search systems,
  • Affective and sentiment information retrieval systems,
  • Proactive search systems,
  • Big Data,
  • Smart City and  Urban Informatics,
  • Content-based and collaborative filtering and recommender systems.
