Group on Recommender Systems

Research with a special focus on responsible recommender systems.

RecSys: Group on Recommender Systems

Our multidisciplinary group works on recommender systems at Tampere University. We focus on various problems, such as:

Recommendations for groups // Sequential recommendations // Fairness, diversity and transparency in recommendations and rankings // Explanations and why-not questions in recommender systems

As well as complementary topics related to the problem of entity resolution, like:

Progressive entity resolution // Iterative blocking and matching // Fairness and diversity in entity resolution // Explanations in entity resolution

We participate in multi-disciplinary research, building on computer science, data science, internet research, social sciences. We aim to design for more ethically sustainable information and communications technology.
