Myrror: a Platform for Quantified Self and Holistic User Modeling.

In this paper we present Myrror, a platform that supports the creation of a unique representation of the user that encodes several facets such as her interests, activities, habits, mood, social connections and so on. Such a representation, that we called holistic user model, is based on the footprints the user spread on social networks and through personal devices. Specifically, our platform acquires personal data coming from several sources, such as Twitter, Facebook, Instagram, Android smartphones and FitBit wristbands, and merges all these information to infer high-level features and populate the facets of the model. Such holistic user models are made available to both the user itself and to third-party services. In the former case, data are shown through a visual interface to improve her self-awareness and her consciousness. In the latter, data are exposed to developers and new personalized services based on these richer user profiles can be created. In both cases, the user has full control over the information she wants to share and unveil.
