Abstract

Context-awareness has been discussed for a long time and is a primary driver of personalization, which is crucial to mobile computing. Additionally, online social networks usually contain enough highly private information for personalization, but this information has been seldom used in modifying the social graph structure. With this paper, we define the novel paradigm of context-centric online social networking in which the social graph structure is derived from context-information alone. We show how a context-centric network based on Wi-Fi location information as well as geohash-based GPS location can be deployed using a specific metadata construction. We support our definitions with a location-based service relying on the metadata model and illustrating spatial and temporal awareness.
