This paper proposes a novel approach for detecting groups of people that walk “together” (group mobility) as well as the people who walk “alone” (individual movements) using wireless signals. We exploit multiple wireless sniffers to pervasively collect human mobility data from people with mobile devices and identify similarities and the group mobility based on the wireless fingerprints. We propose...
Human resource allocation problem is a social problem that has been studied extensively. Aimed at the allocation of human resources, this paper proposed a reasonable mechanism of human resource allocation in which human resource allocation is regarded as the formation of multiple teams. First, tasks submit the skills that they require to the mechanism, and then the mechanism sorts the tasks in a descending...
Participatory sensing has become a promising data collection approach to crowdsourcing data from multi-modal data sources. This paper proposes a generic participatory sensing framework that consists of a set of well-defined modules in support of diverse use cases. This framework incorporates a concept of “human-as-a-sensor” into participatory sensing and allows the public crowd to contribute human...
To date, numerous open source projects are hosted on many online repositories. While some of these projects are active and thriving, some projects are either languishing or showing no development activities at all. This phenomenon thus begs the important question of what are the influential factors that affect the success of open source projects. In a quest to deepen our understanding of the evolution...
