It is unclear if and how collaboratories have enhanced distributed scientific collaboration. Furthermore, little is known in the way of design strategies to support such collaboration. This paper presents findings from an investigation into requirements for collaboration in e-science in the context of CiteSeer, a search engine and digital library of research literature in the computer and infor...

Nowadays, online social networks are considered as one of the most important emerging phenomena of human societies. In these networks, prediction of link by relying on the knowledge existing of the interaction between network actors provides an estimation of the probability of creation of a new relationship in future. A wide range of applications can be found for link prediction such as electro...

One major function of social networks (e.g., massive online social networks) is the dissemination of information such as scientific knowledge, news, and rumors. Information can be propagated by the users of the network via natural connections in written, oral or electronic form. The information passing from a sender to a receiver intrinsically involves both of them considering their self-percei...

On-line social networking sites often involve multiple relations simultaneously. While people can build an explicit social network by adding each other as friends, they can also form several implicit social networks through their daily interactions like commenting on people’s posts, or tagging people’s photos. So given a real social networking system which changes over time, what can we say abo...

The goal of this research is to explore whether network structures common in social networks also emerge in online distance learning networks. We compare the observed values of reciprocity and transitivity in 95 online distance learning networks and 40 social networks with predictions of Random Graph models. All the networks tested exhibit reciprocities that significantly deviate from the predi...

Online networks can be construed as social networks in which people engage in interactions, build relationships, share information, and request and extend assistance to each other using electronic communication technologies. Is social capital embedded in online networks? How is such social capital mobilized (i.e., shared)? What structural properties of cyber networks are associated with mobiliz...

With the proliferation of online social networks, understanding how and why individuals adopt and use online social networks can help managers and marketers to design better methods and approaches towards engaging users of these kinds of networks. The purpose of this study is to investigate the determinants of user acceptance of online social networks, with particular attention given to a resea...
