Members of social networks are given opportunities to bestow positive recognition upon one another by means of constructs such as “likes” and “retweets.” Although recipients no doubt experience utility from these actions, one might question why these constructs with no intrinsic value for the sender are exchanged at all. Here we formulate a metric for the prestige of a member of a social networ...

Collaborative filtering based recommendation methods focus on user-item information for modeling the user interest. However, in social networks the user interest is influenced by other user interests in the local social circle of the active user. In this paper, considering the homophily of relation to similar interests and similar friends, we propose a social item recommendation framework (SocI...

Against close enemies, social authentication is much less effec...

However, little is known about whether Onlies and Others behave differently in the cyber world, especially on the social network.

The Vienna Circle idea that science is an interdisciplinary enterprise leads to the question of how the knowledge of the natural sciences can be used to further understanding in the social sciences. Analysis of the practice of social research shows there is no easy answer to this question. Ideologies colour the use of exact knowledge in social research methods; even in the natural sciences ideo...
