Analysis of roles and groups in blogosphere

In the paper different roles of users in social media, taking into consideration their strength of influence and different degrees of cooperativeness, are introduced. Such identified roles are used for the analysis of characteristics of groups of strongly connected entities. The different classes of groups, considering the distribution of roles of users belonging to them, are presented and discussed.Comment: 8th International Conference on Computer Recognition Systems, CORES 201

Models of Social Groups in Blogosphere Based on Information about Comment Addressees and Sentiments

This work concerns the analysis of number, sizes and other characteristics of groups identified in the blogosphere using a set of models identifying social relations. These models differ regarding identification of social relations, influenced by methods of classifying the addressee of the comments (they are either the post author or the author of a comment on which this comment is directly addressing) and by a sentiment calculated for comments considering the statistics of words present and connotation. The state of a selected blog portal was analyzed in sequential, partly overlapping time intervals. Groups in each interval were identified using a version of the CPM algorithm, on the basis of them, stable groups, existing for at least a minimal assumed duration of time, were identified.Comment: Gliwa B., Ko\'zlak J., Zygmunt A., Models of Social Groups in Blogosphere Based on Information about Comment Addressees and Sentiments, in the K.

The Tumblarians

This paper examines the tumblarians as an information community and discusses community membership, information behaviours, and complementary models for a situated understanding of this unique personal-professional community. A review of the literature concerning LIS bloggers is presented as a complement to the tumblarians, who have no in depth treatment in the research as yet. Characteristics particular to the tumblarians are explored through informal conversation with a community member, and Fisher, Unruh, and Durrance\u27s (2003) information communities model is employed to provide a deeper understanding of the information behaviour of the tumblarians. This paper offers suggestions for future research based on the preliminary findings of the tumblarians as LIS bloggers and a virtual community

Identification of Group Changes in Blogosphere

The paper addresses a problem of change identification in social group evolution. A new SGCI method for discovering of stable groups was proposed and compared with existing GED method. The experimental studies on a Polish blogosphere service revealed that both methods are able to identify similar evolution events even though both use different concepts. Some differences were demonstrated as wellComment: The 2012 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining, IEEE Computer Society, 2012, pp. 1233-123

Jointly they edit: examining the impact of community identification on political interaction in Wikipedia

In their 2005 study, Adamic and Glance coined the memorable phrase "divided they blog", referring to a trend of cyberbalkanization in the political blogosphere, with liberal and conservative blogs tending to link to other blogs with a similar political slant, and not to one another. As political discussion and activity increasingly moves online, the power of framing political discourses is shifting from mass media to social media. Continued examination of political interactions online is critical, and we extend this line of research by examining the activities of political users within the Wikipedia community. First, we examined how users in Wikipedia choose to display (or not to display) their political affiliation. Next, we more closely examined the patterns of cross-party interaction and community participation among those users proclaiming a political affiliation. In contrast to previous analyses of other social media, we did not find strong trends indicating a preference to interact with members of the same political party within the Wikipedia community. Our results indicate that users who proclaim their political affiliation within the community tend to proclaim their identity as a "Wikipedian" even more loudly. It seems that the shared identity of "being Wikipedian" may be strong enough to triumph over other potentially divisive facets of personal identity, such as political affiliation.Comment: 33 pages, 5 figure

The case against the democratic influence of the internet on journalism

Book synopsis: Web Journalism: A New Form of Citizenship provides a much-needed analytical account of the implications of interactive participation in the construction of media content. Although web journalism is a fast-changing technology this book will have sustained appeal to an international readership by seeking to critically assess Internet news production. … With the rise of blogging and citizen journalism, it is a commonplace to observe that interactive participatory media are transforming the relationship between the traditional professional media and their audience. A current, popular, assumption is that the traditional flow of information from media to citizen is being reformed into a democratic dialogue between members of a community. The editors and contributors analyse and debate this assumption through international case studies that include the United Kingdom and United States. … While the text has been written and designed for undergraduate and postgraduate use, Web Journalism: A New Form of Citizenship? will be of use and of interest to all those engaged in the debate over Web reporting and citizen journalism

The Hidden Side of Transparency among Government Agency Bloggers

This paper shows and discusses blogs as social action in a corporate context by investigating and seeking to understand organizational bloggers’ motivations and discursive behaviors in the contextual and cultural diversity of a\ud blog-setting. Providing empirical findings on the possibilities and limitations that are embedded in an organizational blog in a government agency context, traced\ud through focus group interviews of the organizational bloggers, the paper shows that culturally bound limitations exist and are exposed when implementing an open-source social technology like the weblog. People, even within the same organization, have different goals in relation to the same technology, and the transparency of the blog and the blog comments is managed differently by the internal bloggers. Through the discussion of the different cultural discourses at work in the blog, diverging roles and dilemmas that the blogging employees meet when engaging in corporate blogging are exposed and discussed. The aim of the paper is to discuss the social implications of these different cultural discourses in a corporate blog and how corporate cultural tensions emerge because of the blog. The paper pinpoints the problematic of transparency through pointing out conflicting goals, roles and the resulting self-censorship by bloggers as they operate in an environment that is increasingly transparent, and shows examples of\ud how the group of bloggers with the shared narrative tradition is able to mobilize its members and create subgroups for appropriate blog behaviors and changing\ud behavior due to self-censorship, as well as identification with the key actors in the group

The persistence of media control under consolidated authoritarianism: containing Kazakhstan’s digital media

Citizens of Kazakhstan have greater access to the Internet now than at any time in the past. However, the Nazarbaev regime has systematically cut off the supply of political analysis on the country's web sites while simultaneously shifting popular on-line consumption habits in non-political directions. The result is that the presence of the Internet in Kazakhstan is helping the authoritarian regime remain in power
