Test-of-Time Award Winner: Hao Ma, Dengyong Zhou, Chao Liu, Michael R. Lyu, and Irwin King. “Recommender systems with social regularization”, WSDM 2011.
Award Committee’s citation: Recommender systems have proven themselves to be an enduring research topic in academia and industry. The paper was chosen by the committee for its importance and impact on the community. The paper looked at the deep relationship between trust and recommendation, recognizing that users don’t necessarily have similar tastes with everyone they trust, yet that trust is critical to recommendation. Authors helped establish the value of incorporating social signals into the recommender systems by identifying the most suitable social connections for different recommendation tasks. As a result, this paper has high impact (achieving by far the most citations of all the nominations for the WSDM test of time award) but also showed foresight into the importance of trust and transparency in recommendation, which has emerged as an important topic more recently.
