The Social Hourglass: An Infrastructure for Socially Aware Applications and Services

As the Internet's hourglass architecture connects various resources to various applications, an infrastructure that collects information from various social signals can support an ever-evolving set of socially aware applications and services. Among the proposed infrastructure's features are social sensors to capture and interpret social signals from user interactions, a personal social information aggregator, and a set of social-inference functions as its API for social applications.
