The convenience of sharing information online led to a tremendous amount of information available to Web users. The present work examines how people process information in online social networks, using Digg as an example. In Digg, users submit and vote for news stories they like, and the collective decisions of the users determine which news stories become prominent. How do Digg users scan the sea...
Community Wireless Networks (CWNs) not only provide free or affordable Internet access but also facilitate human capital formation. They facilitate human capital accumulation by serving as a venue for brokering knowledge, providing training and enhancing access to information. Previous literature, mostly case studies, shows that CWNs support schools, improve healthcare, provide training and facilitate...
The social capital available to the firm from its external network is the focal topic around which the literature is reviewed. 57 papers obtained from search of the top three journals in strategy field have been reviewed. The paper tries to find the patterns and trends in researches done from the review. The major motive behind this is to find relevant research gap in terms of broad areas left untouched...
In this paper, we investigate the parochialism in dynamic spectrum access networks and its effect on spectrum resource competition and self-coexistence among cognitive radio secondary users. We assume that some greedy secondary users in the network form a parochial community in private and try to maximize their own utilities without concern for the interests of other secondary users outside the community...
This paper describes an attempt to explore possible interrelations between today's online communities, trust and their online social patterns. It reports on a study in progress to provide a deeper understanding of how and at what level such relations affect the development of learning social contexts, i.e contexts that represent individuals needs, group commitments, their responsibilities, goals and...
Human flesh search (HFS) is a recent internet phenomenon. Majority of the academic studies on HFS are in the Chinese context. Many HFS incidents have been reported locally but have been difficult to access by the international community. To resolve this issue and to supplement existing HFS reviews by Chen and Sharma [1], the current study provides a brief HFS analysis in the Taiwanese context with...
Scalable processing of Human Computing tasks by large pools of community members is one of the key opportunities of the modern Social Web. However, the self-organizing nature of Web communities does not allow for guarantees of user commitment and output quality. This is a serious drawback, especially for applications with continuously arriving input data (e.g. reviews and assessments in social streams)...
In recent years, reality mining experiments have provided several novel insights into human social behavior that would not have been possible without the novel use of smart phone sensing. In this work, we leverage the latest reality mining experiment to study social behavior from a public health perspective. In particular, we focus on sleep and mood as they have a considerable public health impact...
We present key insights from two independent projects attempting to foster massive collaboration to solve complex problems. The teams designed frameworks for Massively Collaborative Problem Solving(MCPS) that encourage deep reasoning to emerge by combining small contributions from many distributed individuals. Instead of a linear approach to problem solving, in which many people are asked to perform...
Lifelog research often needs collaboration from many disciplines. Also most related works need very advanced expertise while chances to find all skilled members at one place are very rare. It also involves privacy and/or copyrighted materials where the mutual consent of the use of data is very important. Thus a secure Web-based service is a great way for researchers for technical collaboration to...
Many community networks have emerged on the Internet. They provide various functionalities to serve the community users. However, most of the community networks lacks of the convenient tools in packaging the information users are interested in. Therefore, the information posted and exchanged in the community networks is not easy to be extracted and reused somewhere else. In another aspect, the functions...
Opportunistic networks are formed among mobile wireless devices based on spontaneous connectivity such as mobile phone networks using short range radio. Different setting of social structure in such networks gives significant impact on the feasibility and performance. In this paper we aim at understanding how social structure affects forwarding algorithm in various opportunistic network configurations...
Mobile information systems use publish-subscribe mechanisms to distribute content between users. Unfortunately, content that is close to the user is not necessarily accessible unless users have specified so earlier. Mobile encounter networks (MENs) represent an alternative, which spread content in a spatial diffusion process. A drawback of MENs is their high resource usage. Some researchers have proposed...
This paper presents the results of a multidisciplinary collaboration in Digital Humanities that focuses on the multi-scale analysis of the network of Baroque paintings in the territories of the Hispanic Monarchy from the 16th through the 18th centuries. We apply graph analysis and visualizations as well as natural language analysis over a database of over 11,000 artworks in order to address three...
New mobile phones equipped with multiple sensors provide users with the ability to sense the world at a microscopic level. The collected mobile sensing data can be comprehensive enough to be mined not only for the understanding of human behaviors but also for supporting multiple applications ranging from monitoring/tracking, to medical, emergency and military applications. In this work, we investigate...
Wireless networks growing popularity coupled with a wide availability of wireless-enabled personal devices is today the basis for user-centric Internet architectures to evolve. Central to this new paradigm of user-centricity is the fact that today the Internet end-user exhibits a highly nomadic behavior, where most of the portable devices are carried by humans. The thesis proposed relates to the recent...
Although social network services (SNS) have high possibility as a communication tool, there are many problems as to the use of e-healthcare. It has too many functions and has difficult human interfaces for beginners. Moreover, how introducing a user to an SNS and retain the user's motivation are important issues. Twitter, an SNS that has rapidly advanced in Japan, was selected as the research target...
This paper presents an attempt to provide un understand of the possible trust influence in the successful development of online communities. This was achieved by implementing a research framework who aims to understand what is trust and it role in the online learning communities development and how does that interrelations is related with learners' activity and participation patterns. This research...
Human memory is generally poor and often fails in unpredictable ways, sometimes with dire consequences. On social occasions, it usually causes embarrassing situations (e.g., forgetting the name of a friend). Moreover, as the number of contacts increases, people feel difficult to maintain their social contacts with merely memory. Aiming at helping people better manage their social contacts, a powerful...
Human dynamics are inextricably intertwined with the social, geographical and economic environment. The continuous flux of people communicating as well as migrating, commuting, and traveling inevitably spans acquaintances across geographic space that is far from random and exhibits regular patterns. For instance, it has been shown that the probability of being acquainted with someone is closely related...
