Leveraging Social Context For Searching Social Media, Marc Smith, Vladimir Barash, Lise Getoor, Hady W. Lauw

Research Collection School Of Computing and Information Systems

The ability to utilize and benefit from today's explosion of social media sites depends on providing tools that allow users to productively participate. In order to participate, users must be able to find resources (both people and information) that they find valuable. Here, we argue that in order to do this effectively, we should make use of a user's "social context". A user's social context includes both their personal social context (their friends and the communities to which they belong) and their community social context (their role and identity in different communities).

Do Online Reviews Affect Product Sales? The Role Of Reviewer Characteristics And Temporal Effects, Nan Hu, Ling Liu, Jennifer Zhang

Research Collection School Of Computing and Information Systems

Online product reviews provided by consumers who previously purchased products have become a major information source for consumers and marketers regarding product quality. This study extends previous research by conducting a more compelling test of the effect of online reviews on sales. In particular, we consider both quantitative and qualitative aspects of online reviews, such as reviewer quality, reviewer exposure, product coverage, and temporal effects. Using transaction cost economics and uncertainty reduction theories, this study adopts a portfolio approach to assess the effectiveness of the online review market. We show that consumers understand the value difference between favorable news and …

Library 2.0 And The Problem Of Hate Speech, Margaret Brown-Sica, Jeffrey Beall

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

[First paragraph]

Library 2.0 applications benefit library users by providing rich, peer-generated content that adds value to online library databases and systems. However, not all of this shared content is beneficial, for it’s possible for library users to abuse library 2.0 applications by uploading words, pictures, or other content that constitutes hate speech. Internet lawyer Christopher Wolf warns of, “ … the sudden and rapidly increasing deployment of Web 2.0 technologies to spread messages, sounds and images of hate across the Internet and around the world” [1].

Online Forums As An Arena For Political Discussions: What Politicians And Activists Can Learn From Teachers, Kevin Y. Wang

Scholarship and Professional Work - Communication

This paper discusses the use of online discussion forums in various “e-democratic” practices in light of the lessons learned from the field of education. Informed by a conceptual framework drawn from the role of public sphere in electronic democracy and the ideal learning conditions of a computer-mediated communication environment, the author analyzed two discussion forums maintained by a government and a civil society group. Results suggest that, in both cases, online discussion forums only reflect a few elements of effective online learning and therefore, have yet to reach their full potentials. Implications for future research are discussed.

Research outputs pre 2011

This article will look at the use of personal photographs that attempt to convey a sense of social activism as a reaction against global terrorism. Moreover, I argue that the photographs uploaded to the site “We’re Not Afraid”, which began after the London bombings in 2005, presents a forum to promote the pleasures of western cultural values as a defence against the anxiety of terror. What is compelling are the ways in which the Website promotes, seemingly, everyday modalities through what may be deemed as the domestic snapshot. Nevertheless, the aura from the context of these images operates to arouse …
