abstract = {An important problem with online communities in general, and online rating systems in particular, is uncooperative behavior: lack of user participation, dishonest contributions. This may be due to an incentive structure akin to a Prisoners' Dilemma (PD). We show that introducing an explicit social network to PD games fosters cooperative behavior, and use this insight to design a new aggregation technique for online rating systems. Using a dataset of ratings from Yelp, we show that our aggregation technique outperforms Yelp's proprietary filter, as well as baseline techniques from recommender systems.

abstract = {Social networks can play an important role in the process of decentralizing authority in distributed systems. We will focus on distributed wiki systems, and we show how, in the special case of a peer-to-peer wiki, there is a rational incentive for users to self-organize and form a meaningful social network. We discuss to that effect the basic metrics that can be derived from the topology of the social network to help assess the subjective quality of wiki entries. Demos and experimental results will illustrate and support our discussion. We finally speculate as to how these results may also translate to discussion forums or recommender systems. © 2016 International World Wide Web Conference Committee (IW3C2).},
