Cité Internationale Universitaire de Paris

Grand salon de la Maison du Cambodge, 17 bd Jourdan 75014 Paris

The conference starts Thursday December 18 at 1 p.m. and ends Saturday December 20 at 1 p.m.

Parallel to the development of Internet, there has been a significant growth in methods that rank various items such as Web pages, recommend purchases to customers or political parties to citizens, seek for reviewers of products, evaluate the trustworthiness of reviewers, recommend friends or colleagues in social networks, and so on. The purpose of the workshop is to gather people working on these topics in different disciplines, economics, game theory, marketing and computer science.

Topics include but are not limited to :

  • design of recommendation systems
  • design of rating systems
  • customers’ behaviors and learning
  • interaction between online recommendations and experts
  • value of information.

Organizer : Gabrielle Demange, Supported by ANR NET

The workshop is open. For a good organization, please register by sending an email to Beatrice Havet : beatrice.havet@ens.fr.
