Colm O Fearghail has joined the group as an Academy of Finland funded post-doctoral researcher!
We use reinforcement learning and user modelling to develop practical systems that help users navigate massive data sets interactively. The research interests of the group include personalisation, exploratory search, experimental design and evaluation methodology. Our research is published in top venues for information retrieval and human-computer interaction. We are part of the Department of Computer Science at the University of Helsinki.
Representative publications:
Bandit algorithms in information retrieval Foundations and Trends in IR
Towards fine-grained adaptation of exploration/exploitation in information retrieval IUI 2017
Is exploratory search different? A comparison of information search behavior for exploratory and lookup tasks JASIST 2016
Balancing exploration and exploitation: Empirical parameterization of exploratory search systems CIKM 2015
