Interest In Technology

Social web sites are used daily by many millions of users. They have attracted users with very weak interest in technology, including absolute neophytes of computers in general. Common users of social web sites often have a carefree attitude in sharing information. Moreover, some system operators offer sub-par security measures, which are not adequate for the high value of the published information. For all these reasons, online social networks suffer more and more attacks by sophisticated crackers and scammers. To make things worse, the information gathered from social web sites can trigger attacks to even more sensible targets. This work reviews some typical social attacks that are conducted on social networking systems, describing real-world examples of such violations and analyzing in particular the weakness of password mechanisms. It then presents some solutions that could improve the overall security of the systems.

Managers are increasingly interested in the social web, as it provides numerous opportunities for strengthening and expanding relationships with customers, but the network processes that lead to these user-based assets are poorly understood. In this paper, the authors explore factors influencing use and participation in virtual social networks. They also discuss unusual drivers and inhibitors present with virtual social networks—highlighted by the presence of positive network externalities and fears that the content will be misused. The authors offer hypotheses stemming from a model of how these factors work together, test the model with a dataset collected from two different virtual social networks, and discuss the implications of this work. The findings offer managers insights on how to nurture Web 2.0 processes.

Dot Com

Online social networking services have come to dominate the dot com world: Countless online communities coexist on the social Web. Some typically characteristic user attributes, such as gender, age group, sexual orientation, are not automatically part of the profile information. In some cases user attributes can even be deliberately and maliciously falsified. This paper examines automated inference of gender on online social networks by analyzing written text with a combination of natural language processing and classification techniques. Extensive experimentation on LinkedIn and Twitter has yielded accuracy of this gender identification technique of up to 98.4 percent.

The Social

This article addresses issues of user precarity and vulnerability in online social networks. As social media criticism by Jose van Dijck, Felix Stalder, and Geert Lovink describes, the social web is a predatory system that exploits users’ desires for connection. Although accurate, this critical description casts the social web as a zone where users are always already disempowered, so fails to imagine possibilities for users beyond this paradigm. This article examines Natalie Bookchin’s composite video series, Testament, as it mobilizes an alt-(ernative) social network of vernacular video on YouTube. In the first place, the alt-social network works as an iteration of “tactical media” to critically reimagine empowered user-to-user interactions on the social web. In the second place, it obfuscates YouTube’s data-mining functionality, so allows users to socialize online in a way that evades their direct translation into data and the exploitation of their social labor.

Influential Users

The social web appears to enrich human lives by providing effective applications for online social interactions. Microblogs are one of the most important applications of the social Web. The Microbloggers who influence the social community users through their content in the form of tweets are known as the influential microbloggers. The identification of such influential microbloggers has vast applications in advertising, online marketing, corporate communication, information dissemination, etc. This paper investigates the problem of identifying influential microbloggers by proposing MIPPLA (Model to identify Influential using Productivity, Popularity and Link Analysis) model which integrates the modules of Productivity and Popularity. The Productivity module considers a micro-blogger’s activity and the Popularity module identifies a microbloggers influence in an online social community. In addition, we modify the classic PageRank by utilizing the Twitter features such as retweet, mention, and reply for ranking the influential users. The proposed approaches are evaluated using real-world social networks. The results prove that the MIPPLA model efficiently identifies and ranks the top influential users in an effective manner as compared to the existing techniques.

The Relationship

In this text, we reflect about the relationship between the Portuguese National Film Plan and the Social Networks, in the context of the current (network) society, presenting, for this purpose, the ongoing research project “Education, Film, Social Networks: a study about the Portuguese National Film Plan.” The theoretical framework of the study includes the concepts of open education and audiovisuals, envisaged under the theoretical triad Education / Film / Social Networks, with the aim of understanding how this Plan makes use of online digital social networks, the paradigmatic example of the tools associated to the social web. Moreover, the relationship between film, education and social networks is considered in particular, taking into account the digital lifestyles of contemporary society and the importance of developing and disseminating different literacies. Such reflections will also take into account the practice of the National Film Plan, an initiative of the Portuguese government created to promote the development of film literacy in the school environment. Finally, it will be possible to conclude that the connection between film and education goes back to the origins of film itself, having evolved not only with filmic technologies and pedagogical methodologies, but also with the influence of the new lifestyles in society. Thus, in today’s digital, online and audiovisual society, and since the relationship between cinema and education is dynamic too, it now finds both other challenges and new opportunities.

Virtual Volunteering

Social interaction technologies create communicative possibilities that go beyond dyadic interactions and across physical boundaries, bringing a qualitative shift in the functioning of the Internet. The present chapter employs social capital and social networks perspectives to identify the social determinants of virtual volunteering in the age of Web 2.0, explores the social motivation of volunteers who perform tasks using the Social Web in the context of online volunteering, and addresses the dynamic interplay of social capital, social networks, and the Social Web with implications for virtual volunteering. The argument furthered is that active participation in social networks generates social capital and facilitates the development of the Social Web.

New Forms Of Learning

In recent years, new socially-oriented Web technologies have been portrayed as placing the learner at the centre of networks of knowledge and expertise, potentially leading to new forms of learning and education. In this paper, I argue that commercial social networks are much less about circulating knowledge than they are about connecting users (“eyeballs”) with advertisers; it is not the autonomous individual learner, but collective corporate interests that occupy the centre of these networks. Looking first at Facebook, Twitter, Digg and similar services, I argue their business model restricts their information design in ways that detract from learner control and educational use. I also argue more generally that the predominant “culture” and corresponding types of content on services like those provided Google similarly privileges advertising interests at the expense of users. Just as commercialism has rendered television beyond the reach of education, commercial pressures threaten to seriously limit the potential of the social Web for education and learning.
