—Increasingly popular location-based services can monitor our geographical positions in real time and so can provide a fundamental source for capturing users feelings and personal attitudes towards a particular place at a particular time. We propose a novel procedure for the representation of places through weighted tag-lists based on user reviews on these(More)
Through web sites such as Twitter, micro-blogging has shown a remarkable growth, demonstrating the human desire to share and consume information and knowledge. At the same time, the capabilities of mobile devices such as smart phones has considerably increased, opening up new ways to communicate and share content. In particular it is becoming feasible that(More)
—Location-sharing services such as Foursquare provide a rich source of information about the visits of users to locations. In the case of Foursquare, users voluntarily 'check in' to places they visit using a mobile application. An analysis of these data may reveal differences in users personality in terms of their mobility habits, preferred places, and(More)
—We present results from a web-based experiment conducted to assess the effect of Twitter metadata on decision making in content consumption. Participants were presented with information concerning two tweets and asked which they would prefer to read. Analysis of the results shows that recognition of the author as being within the readers local network is(More)
Micro-blogging services have recently been experiencing increasing success among Web users. Different to traditional online social applications, micro-blogs are lightweight, require small cognitive effort and help share real-time information about personal activities and interests.

—This paper considers an adaptive data dissemination scenario that applies an autonomic trust protocol to a network of agents. The protocol uses social network structures to incentivize cooperation. Validation is conducted through a prisoners dilemma based simulation which uses similarity of interest between peers to define payoff. Positive correlation is(More)
—Epidemic type exchange protocols have often been discussed as a means of disseminating information through a network of nodes. These protocols may be applied to mobile opportunistic ad-hoc networks where the goal is not total dissemination of all information to all nodes but where nodes are interested in attaining specific content for which they have a(More)
The performance of many emerging communication paradigms depend on high levels of cooperation amongst the peers in the network. Although an individual’s best strategy may be to selfishly consume resources without reciprocation, the optimal social performance requires agents in the network to behave in an altruistic manner. This paper considers a P2P(More)
