Platys Social: Relating Shared Places and Private Social Circles

Social circles can be valuable in online applications, but existing approaches don´t readily support such grouping: they either require a user to manually tag connections or offer no more than broad-brush acquaintanceship between connections. Platys Social is a novel approach that learns users´ social circles and prioritizes their connections by bringing together contextual information and user interactions. Platys Social runs incrementally, can execute on a resource-limited mobile device, and can potentially avoid storing users´ private information on a remote site.
