We also found reciprocity to help with the cold start problem obtaining a success rate of 26% for the top ten recommendations for new users.  ...  We investigated the predictive power gained by taking account of reciprocity, finding that it is substantial, for example it improved the success rate of the top ten recommendations from 26% to 45% and  ...  This supports our hypothesis that reciprocity is important for recommender systems that involve people in both sides of the recommendations (i.e. reciprocal recommenders).  ...

Finding Someone You Will Like and Who Won't Reject You [chapter]

Luiz Augusto Pizzato, Tomek Rej, Kalina Yacef, Irena Koprinska, Judy Kay
2011 Lecture Notes in Computer Science  
This paper explores ways to address the problem of the high cost problem of poor recommendations in reciprocal recommender systems.  ...  These systems recommend one person to another and require that both people like each other for the recommendation to be successful.  ...  This might mean that, compared with conventional recommenders, the reciprocal recommender may need to find recommendations that may not be a particularly good match to the user's preference model; in this  ...
