Ph.D. candidate Evangelia Christakopoulou and Professor George Karypis received the best paper award at the 10th ACM Conference on Recommender Systems for their paper “Local Item-Item Models for Top-N Recommendation.”

This paper generalizes and improves upon the widely popular item-item method for computing top-N recommendations by explicitly modeling the fact that not all users behave the same way; rather, there exist subsets of like-minded users. The paper presented an approach that simultaneously identifies these like-minded user subsets along with their associated item-item recommendation models in order to maximize the overall recommendation performance. 

The conference was held in Boston and is a premier international forum for the presentation of new research, results, systems and techniques in the broad field of recommender systems. This year’s published papers went through a rigorous peer review process, with an acceptance rate under 20%.

Congratulations to Evangelia Christakopoulou and Professor Karypis on this award.
