Query: Towards Fair Recommendation in Two-Sided Platforms   Many online platforms today (such as Amazon, Netflix, Spotify, LinkedIn, and
AirBnB) can be thought of as two-sided markets with producers and customers of
goods and services. Traditionally, recommendation services in these platforms
have focused on maximizing customer satisfaction by tailoring the results
according to the personalized preferences of individual customers. However, our
investigation reinforces the fact that such customer-centric design of these
services may lead to unfair distribution of exposure to the producers, which
may adversely impact their well-being. On the other hand, a pure
producer-centric design might become unfair to the customers. As more and more
people are depending on such platforms to earn a living, it is important to
ensure fairness to both producers and customers. In this work, by mapping a
fair personalized recommendation problem to a constrained version of the
problem of fairly allocating indivisible goods, we propose to provide fairness
guarantees for both sides. Formally, our proposed {\em FairRec} algorithm
guarantees Maxi-Min Share ($\alpha$-MMS) of exposure for the producers, and
Envy-Free up to One Item (EF1) fairness for the customers. Extensive
evaluations over multiple real-world datasets show the effectiveness of {\em
FairRec} in ensuring two-sided fairness while incurring a marginal loss in
overall recommendation quality. Finally, we present a modification of FairRec
(named as FairRecPlus) that at the cost of additional computation time,
improves the recommendation performance for the customers, while maintaining
the same fairness guarantees.
