Social Ranking Techniques for the Web

The proliferation of social media has the potential for changing the structure and organization of the web. In the past, scientists have looked at the web as a large connected component to understand how the topology of hyperlinks correlates with the quality of information contained in the page and they proposed techniques to rank information contained in web pages. We argue that information from web pages and network data on social relationships can be combined to create a personalized and socially connected web. In this paper, we look at the web as a composition of two networks, one consisting of information in web pages and the other of personal data shared on social media web sites. Together, they allow us to analyze how social media tunnels the flow of information from person to person and how to use the structure of the social network to rank, deliver, and organize information specifically for each individual user. We validate our social ranking concepts through a ranking experiment conducted on web pages that users shared on Google Buzz and Twitter.Comment: 7 pages, ASONAM 201

The other side of the social web: A taxonomy for social information access

The power of the modern Web, which is frequently called the Social Web or Web 2.0, is frequently traced to the power of users as contributors of various kinds of contents through Wikis, blogs, and resource sharing sites. However, the community power impacts not only the production of Web content, but also the access to all kinds of Web content. A number of research groups worldwide explore what we call social information access techniques that help users get to the right information using "collective wisdom" distilled from actions of those who worked with this information earlier. This invited talk offers a brief introduction into this important research stream and reviews recent works on social information access performed at the University of Pittsburgh's PAWS Lab lead by the author.

Asian Government Usage of Web 2.0 Social Media

The rise of Web 2.0 social sites, such as Facebook, Twitter and YouTube has brought significant changes and opportunities for both online consumers and governments. These tools have changed the ways Internet users communicate with each other and their governments, and allow for greater social participation. The number of worldwide users is growing significantly and their expectations for more services are rising. However, this has not translated into Asian governments totally encompassing the implementation functions and services using these tools. This research investigates the level of government participation of 50 Asian governments of three social media sites. The results show that a minority of Asian governments (approximately 30 percent) are using Web 2.0 tools for communication and information dissemination. The study found that if social sites were utilised, most governments used them for a) information dissemination on official government channels, b) education and c) tourism. The implications are that governments are missing opportunities to better server their citizens and reach the growing number of Internet users. Instead of avoiding these new technologies, governments should develop an overall strategic plan for all agency levels to participate in social networks, and develop a coordinated effort to develop and implement the tools

Self-Imposed Violations of Privacy in Virtual Communities

Virtual communities have grown in recent years due to the accessibility and ease of setting up web pages on communal Internet sites. Organizations, including companies that seek to hire new employees, often scan these web sites as part of their background checking process. One of the most prominent sites is MySpace.com. This research investigates issues of privacy and self-violation of privacy in virtual communities. The results indicate that individuals willingly provide personal information that may actually violate their privacy.Virtual communities; privacy; violations of privacy; MySpace; Information Systems; online social networks.
