The online environment brings us a panoply of variety. There are far more products than could be found on any High Street, far more music than might be heard on any radio station, and far more content than might be seen on any TV channel.With variety comes the problem of choice. How do we navigate all these options? Recommender systems (RS) can help by providing personalised recommendations.
But this involves a process of prediction that can generate systemic biases. A team from the Universities of East Anglia and Liverpool, and City University have looked at how such biases risk not only worsening end-user choices but also harming competition between suppliers on the platform.
With this workshop, the team will share the findings of their work with policy stakeholders, to foster the policy debate around recommender systems, and inform future research.
