an ad-hoc network based intelligent system working on swarm intelligence principles for socializing system is being presented. The architecture relies on the distributed and decentralized nature and combines the swarm intelligence and crowdsourcing in mobiles. Mobile devices detect the current context, developing information structures about the person condition and inform the other people in t...

We consider social networks in which links are associated with a sign; a positive (negative) sign indicates friendship (animosity) between the connected nodes. Recent work studies such large online signed networks by applying theories that stem from the notion of social balance. Computing the social balance of a signed network requires counting the distinct configurations of the signed edges wi...

With the advance of the Internet and the increasing accessibility of computing resources, humans and computer systems are now brought together in powerful new ways. In this paper, we propose a humancentered computing framework to harness the essential characteristics of both humans and computers for achieving collaborative image understanding (i.e., training large numbers of inter-related class...

With the emergence of smarthphones and social networks, a very large proportion of communication takes place on short texts. This type of communication, often anonymous, has allowed a new public participation in political issues. In particular, electoral phenomena all over the world have been greatly influenced by these networks. In the recent elections in Mexico, Twitter became a virtual place...

Social computing focuses on the interaction between social behavior and information, especially on how the latter propagates across social networks and is consumed and transformed in the process. At the same time the ubiquity of information has left it devoid of much monetary value. The scarce, and therefore valuable, resource is now attention, and its allocation gives rise to an attention econ...

The research on values has always been a spot in the field of deep-seated culture in social science. In particular, the research on population values shaping is more practical. Model users especially refer to decision makers for population values affairs (UPVs for short) require more effective way of shaping overall population values to maintain the deep-seated cultural safety of the whole popu...

Communities are the latest phenomena on the Internet. At the heart of each community lies a social network. In this paper, we show a generalized framework to understand and reason in social networks. Previously, researchers have attempted to use inference-specific type of relationships. In this paper, we propose a framework to represent and reason with general case of social relationship networ...

We can notice that the general public awareness on ethical aspects of technology is increasing. The high level of media attention given to computerrelated disasters in technical systems such as the explosion of Ariane V in 1996 and the Therac-25 computerized radiation machine overdoses has increased interest in Computer Ethics. The aim of this paper is to shed light upon the significance of soc...

The Web is deep into its second decade of life, and since 1991 it has dramatically changed the way the connected world operates. As the Web has shifted to an interactive environment where much content is created by users, the question of whom to trust and what information to trust has become both more important and more difficult to answer. One promising solution is using social trust relations...
