Akiva Kleinerman, Ariel Rosenfeld, Francesco Ricci, Sarit Kraus
2018 Proceedings of the 12th ACM Conference on Recommender Systems - RecSys '18  
For each user receiving a recommendation, our method finds the optimal balance of two criteria: a) the likelihood of the user accepting the recommendation; and b) the likelihood of the recommended user  ...  These recommender systems benefit from contemplating the interest of both sides of the recommended match, however the question of how to optimally balance the interest and the response of both sides remains  ...  Optimally Balancing Receiver and Recommended Users' Importance In Algorithm 2 we give the general scheme for our recommendation algorithm, where ServiceU ser Features (row 10) is a function which obtains  ...

Recommender Systems as Multistakeholder Environments

Himan Abdollahpouri, Robin Burke, Bamshad Mobasher
2017 Proceedings of the 25th Conference on User Modeling, Adaptation and Personalization - UMAP '17  
For example, fairness and balance across stakeholders is important in some recommendation applications; achieving a goal such as promoting new sellers in a marketplace might be important in others.  ...  In research practice, recommender systems are typically evaluated on their ability to provide items that satisfy the needs and interests of the end user.  ...  Fairness and balance are important examples of system-level objectives, and these social-welfare-oriented goals may at times run counter to individual preferences.  ...

Stochastic matching and collaborative filtering to recommend people to people

Luiz Augusto Pizzato, Cameron Silvestrini
2011 Proceedings of the fifth ACM conference on Recommender systems - RecSys '11  
In this paper, we use collaborative filtering to generate recommendations for all users, and by using stochastic matching we select a number of reciprocal recommendations for each user that maximizes the  ...  In this way, all users, regardless of their popularity, will receive the same number of recommendations the number of times they will be recommended to others.  ...  When looking into the popularity spectrum and people recommender systems, there is a right balance between the number of recommendations that each user should receive and the number of times they should  ...

Patterns of Multistakeholder Recommendation [article]

Robin Burke, Himan Abdollahpouri
2017 arXiv   pre-print
However, in many settings, the end-user of the recommendations is not the only party whose needs must be represented in recommendation generation.  ...  Recommender systems are personalized information systems.  ...  Here there is a form of reciprocation in that the ad should be appealing to the user and the user should be in the defined target audience.  ...

Multi-Stakeholder Recommendation: Applications and Challenges [article]

Yong Zheng

Personalizing Fairness-aware Re-ranking [article]

Weiwen Liu, Robin Burke
2018 arXiv   pre-print
Personalized recommendation brings about novel challenges in ensuring fairness, especially in scenarios in which users are not the only stakeholders involved in the recommender system.  ...  For example, the system may want to ensure that items from different providers have a fair chance of being recommended.  ...  The system receives items from providers and recommends them to the consumers.  ...
