This paper proposes a method to construct an evaluation dataset from microblogs for the development of recommendation systems.We extract the relationships among three main entities in a recommendation event, i.e., who recommends what to whom.User-to-user friend relationships and user-to-resource interesting relationships in social media and resource-to-metadata descriptions in an external ontology are employed.In the experiments, the resources are restricted to visual entertainment media, movies in particular.A sequence of ground truths varying with time is generated.That reflects the dynamic of real world.
