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:

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.
UPDATE: the official advert is now available online here.
Welcome to Jing Li and Yu An who have joined the group as summer interns!
Dorota’s book, Bandit Algorithms in Information Retrieval, has just been released!
Paper accepted at LAW13 (13th Linguistic Annotation Workshop, 2019)!
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.
