The rising popularity of social computing systems has managed to attract rampant forms of service abuse that negatively affects the sustainability of these systems and degrades the quality of service experienced by their users. The main factor that enables service abuse is the weak identity infrastructure used by most sites, where identities are easy to create with no verification by a trusted ...

Pervasive systems are becoming increasingly popular, with the appearance and penetration of mobile devices such as smart phones. Proactive service is one of the most important fields of research in pervasive computing. We propose a method for an effective proactive service in pervasive computing environment. Most of previous researches do not consider characteristics of both social network and ...

Despite an increasing popularity, the impact and benefits of corporate social computing remain unclear. This paper aims at rigorously studying social computing tools as a new class of technology and provides a holistic definition and characterization. After a comprehensive literature review, we empirically explored the defining attributes and underlying dimensions of social computing as a whole...

People have begun to accept technology as a matter of course in the day-to-day areas of their lives. As a result, the development and proliferation of social software has enjoyed exponential growth in the past several years. In this paper we argue that as researchers and practitioners who create social technologies, we must take a “social engineering” approach, actively designing social applica...

in order to improve the level of intelligence, availability, being on demand, convenience, information and humanization of rural public transportation systems, they are more willing to use modern information and communicative technologies. in addition to management services, intelligent transportation systems can provide passengers, drivers, travel agencies and other institutions with other ser...
