Topical Keyphrase Extraction From Twitter, Xin Zhao, Jing Jiang, Jing He, Yang Song, Palakorn Achananuparp, Ee Peng Lim, Xiaoming Li

Research Collection School Of Computing and Information Systems

Summarizing and analyzing Twitter content is an important and challenging task. In this paper, we propose to extract topical keyphrases as one way to summarize Twitter. We propose a context-sensitive topical PageRank method for keyword ranking and a probabilistic scoring function that considers both relevance and interestingness of keyphrases for keyphrase ranking. We evaluate our proposed methods on a large Twitter data set. Experiments show that these methods are very effective for topical keyphrase extraction.

Internet History, Raphael Cohen-Almagor

raphael cohen-almagor

This paper outlines and analyzes milestones in the history of the Internet. As technology advances, it presents new societal and ethical challenges. The early Internet was devised and implemented in American research units, universities, and telecommunication companies that had vision and interest in cutting-edge research. The Internet then entered into the commercial phase (1984-1989). It was facilitated by the upgrading of backbone links, the writing of new software programs, and the growing number of interconnected international networks. The author examines the massive expansion of the Internet into a global network during the 1990s when business and personal computers with different …

Utility-Oriented K-Anonymization On Social Networks, Yazhe Wang, Long Xie, Baihua Zheng, Ken C. K. Lee

Research Collection School Of Computing and Information Systems

"Identity disclosure" problem on publishing social network data has gained intensive focus from academia. Existing k-anonymization algorithms on social network may result in nontrivial utility loss. The reason is that the number of the edges modified when anonymizing the social network is the only metric to evaluate utility loss, not considering the fact that different edge modifications have different impact on the network structure. To tackle this issue, we propose a novel utility-oriented social network anonymization scheme to achieve privacy protection with relatively low utility loss. First, a proper utility evaluation model is proposed. It focuses on the changes on …

Comparing Twitter And Traditional Media Using Topic Models, Wayne Xin Zhao, Jing Jiang, Jianshu Weng, Jing He, Ee Peng Lim, Hongfei Yan, Xiaoming Li

Research Collection School Of Computing and Information Systems

Twitter as a new form of social media can potentially contain much useful information, but content analysis on Twitter has not been well studied. In particular, it is not clear whether as an information source Twitter can be simply regarded as a faster news feed that covers mostly the same information as traditional news media. In This paper we empirically compare the content of Twitter with a traditional news medium, New York Times, using unsupervised topic modeling. We use a Twitter-LDA model to discover topics from a representative sample of the entire Twitter. We then use text mining techniques to …

The Rise Of The New Experts: Decision-Making In The Art World In The Digital Age, Payal Arora, Filip Vermeylen

Payal Arora

In this digital age, declarations surface on the death of the expert. Crowd wisdom is instead seen as the new guide to constructing and evaluating knowledge. In the context of the art world, this tension between the amateurs and the experts becomes particularly pronounced as popular meets high culture. Questions arise such as what is the role of the amateur in the evaluation of art in current times? Does social media level the playing field here and can we assume that equity in participation results in better judgments? Does online participation on art valuation impact its actual market pricing? Who …

Online Social Sites As Virtual Parks: An Investigation Into Leisure Online And Offline, Payal Arora

Payal Arora

Currently, there is much excitement about Web 2.0 as a novel platform for experiencing, producing, and consuming leisure, particularly through social network sites. Conversely, there are skeptics who sound the alarm on these spaces, viewing them as diluting of human relations. The perspective that guides this article is invested in neither a utopian nor a dystopian posture, but sees historical continuity, pointing out that performing leisure is a basic human impulse that has found expression over the centuries. With regard to the online sites used for leisure, it makes the case that the history of the development of the public …

Cosmopolitanism And Suppression Of Cyber-Dissent In The Caucasus: Obstacles And Opportunities For Social Media And The Web, Brian J. Bowe, Robin Blom

Brian J. Bowe

Around the world, social media offer an informal virtual space for citizens who feel disenfranchised to connect socially. But for those who live in countries such as the three former Soviet republics of the Caucasus — where free expression is curtailed and official news outlets are under government censorship — information and communication technology (ICT) offers an increasingly important alternative vehicle for political expression. Recent developments in Tunisia, Egypt, and Iran demonstrate how blogging and social media tools may fulfill a crucial role for non-journalists and oppositional groups that journalism serves in more democratic societies. This article considers the use …

Expert Stock Picker: The Wisdom Of (Experts In) Crowds, Shawndra Hill, Noah Ready-Campbell

Operations, Information and Decisions Papers

The phrase "the wisdom of crowds" suggests that good verdicts can be achieved by averaging the opinions and insights of large, diverse groups of people who possess varied types of information. Online user-generated content enables researchers to view the opinions of large numbers of users publicly. These opinions, in the form of reviews and votes, can be used to automatically generate remarkably accurate verdicts-collective estimations of future performance-about companies, products, and people on the Web to resolve very tough problems. The wealth and richness of user-generated content may enable firms and individuals to aggregate consumer-think for better business understanding. Our …

Social Media At Academia's Periphery: Studying Multilingual Developmental Writers' Facebook Composing Strategies, Kevin Eric Depew

English Faculty Publications

This article focuses on the writing strategies second-language students use to compose on social media sites. These alternative and unconventional sites for learning provide language learners opportunities to acquire language by using multiple modalities to respond to various rhetorical situations. In comparison to these sites, academic writing contexts, particularly the developmental-writing course, impose monolingual norms and deficient identities on students. Where these courses articulate these language learners as possessing inadequate skills to perform well in mainstream writing courses, the students' social-media compositions demonstrate that these students have the potential to respond to communicative situations in rhetorically complex ways. This study …

Cacophony Or Empowerment? : Analyzing The Impact Of New Information Communication Technologies And New Social Media In Southeast Asia., Jason P. Abbott

Faculty Scholarship

The capabilities, tools and websites we associate with new information communication technologies and social media are now ubiquitous. Moreover tools that were designed to facilitate innocuous conversation and social interaction have had unforeseen political impacts. Nowhere was this more visible than during the 2011 uprisings across the Arab World. From Tunis to Cairo, and Tripoli to Damascus protest movements against authoritarian rule openly utilized social networking and file sharing tools to publicize and organize demonstrations and to catalogue human rights abuses. The Arab Spring, or Jasmine Revolution, was an event that was both witnessed and played out in real time …

Librarianship Presence In Virtual Worlds, Jenny M. Baum, Kate Lyons

Publications and Research

Librarianship has stereotypically been about books, communities, and the connection between the two. With the emergence of new media and technology, the concept of books has expanded to include information of all types and in multiple formats: eBooks, DVDs, videogames, electronic databases, et cetera. Meanwhile, the idea of community has stayed the same. For example, public libraries primarily serve communities defined by geographic lines; academic libraries serve their campus communities. In non-profit, medical or corporate libraries, communities are defined by their organization’s particular mission. However, now that virtual worlds are becoming mainstream, librarians are redefining community, just as they redefined …

Sexuality, Exoticism, And Iconoclasm In The Media Age: The Strange Case Of The Buddha Bikini, James Shields

Faculty Contributions to Books

It is widely acknowledged that we in the West are living in an age of both rampant consumerism and competing religious faiths. In addition, those of us living in the United States of America inhabit a society with striking variation when it comes to what is considered appropriate sexual or bodily display, especially when it comes to women’s bodies. The hullabaloo surrounding Janet Jackson’s infamous “wardrobe malfunction” brought to light some of these tensions, at the single most important religious spectacle in America, no less, the Super Bowl. Though admittedly less well known, another recent scandal even more clearly raises …
