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:

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
Directing exploratory search: Reinforcement learning from user interactions with keywords IUI 2013
We are looking to hire a PhD student to work on interactive information retrieval, user modelling and human-computer interaction! Ideal starting date is Summer/Autumn 2019. We have yet to send out an official advertisement, but if you are interested, please send an up-to-date CV together with a description of your research interests to Dorota.
A big thank you to everyone who submitted papers, reviewed and helped with the organisation of the Workshop on Exploratory Search and Interactive Data Analytics (ESIDA) hosted at IUI 2019.
Alan presented How Relevance Feedback is Framed Affects User Experience, but not Behaviour and Arlene (pictured) presented Holes in the Outline: Subject-dependent Abstract Quality and its Implications for Scientific Literature Search at CHIIR 2019 in Glasgow, Scotland.
We are looking to hire summer interns for several human-computer interaction, information retrieval and machine learning projects! See here for project descriptions. If you are interested or would like more information about a specific project, please email either Dorota or Alan. All internship positions have been filled. Thank you for your interest!
The group has moved back to the Department of Computer Science, University of Helsinki. Moi moi Edinburgh!
