The 2008 Us Presidential Election And New Digital Technologies: Political Campaigns As Social Movements And The Significance Of Collective Identity, Stephanie Takaragawa, Victoria Carty

Sociology Faculty Articles and Research

The growing role of the Internet social networking sites (SNS) has served as a flash point for debate about the democratization of information, particularly in light of their perceived roles in the 2008 presidential election. This horizontal sharing of information undoubtedly facilitated the revival of the youth vote and volunteerism in many ways mimicking traditional grassroots approaches. While the role of the Internet SNS in mobilization efforts and information-sharing cannot be overstated, its effectiveness in creating a new “public sphere,” or transforming traditional electoral campaign strategies and communicative practices must be closely examined before generalizations about the democratization of media …

On Recommending Hashtags In Twitter Networks, Su Mon Kywe, Tuan-Anh Hoang, Ee Peng Lim, Feida Zhu

Research Collection School Of Computing and Information Systems

Twitter network is currently overwhelmed by massive amount of tweets generated by its users. To effectively organize and search tweets, users have to depend on appropriate hashtags inserted into tweets. We begin our research on hashtags by first analyzing a Twitter dataset generated by more than 150,000 Singapore users over a three-month period. Among several interesting findings about hashtag usage by this user community, we have found a consistent and significant use of new hashtags on a daily basis. This suggests that most hashtags have very short life span. We further propose a novel hashtag recommendation method based on collaborative …

Community-Based Classification Of Noun Phrases In Twitter, Freddy Chong Tat Chua, William W. Cohen, Justin Betterridge, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Many event monitoring systems rely on counting known keywords in streaming text data to detect sudden spikes in frequency. But the dynamic and conversational nature of Twitter makes it hard to select known keywords for monitoring. Here we consider a method of automatically finding noun phrases (NPs) as keywords for event monitoring in Twitter. Finding NPs has two aspects, identifying the boundaries for the subsequence of words which represent the NP, and classifying the NP to a specific broad category such as politics, sports, etc. To classify an NP, we define the feature vector for the NP using not just …

Finding Thoughtful Comments From Social Media, Gottipati Swapna, Jing Jiang

Research Collection School Of Computing and Information Systems

Online user comments contain valuable user opinions. Comments vary greatly in quality and detecting high quality comments is a subtask of opinion mining and summarization research. Finding attentive comments that provide some reasoning is highly valuable in understanding the user’s opinion particularly in sociopolitical opinion mining and aids policy makers, social organizations or government sectors in decision making. In this paper we study the problem of detecting thoughtful comments. We empirically study various textual features, discourse relations and relevance features to predict thoughtful comments. We use logistic regression model and test on the datasets related to sociopolitical content. We found …

A Survey Of Recommender Systems In Twitter, Su Mon Kywe, Ee Peng Lim, Feida Zhu

Research Collection School Of Computing and Information Systems

Twitter is a social information network where short messages or tweets are shared among a large number of users through a very simple messaging mechanism. With a population of more than 100M users generating more than 300M tweets each day, Twitter users can be easily overwhelmed by the massive amount of information available and the huge number of people they can interact with. To overcome the above information overload problem, recommender systems can be introduced to help users make the appropriate selection. Researchers have began to study recommendation problems in Twitter but their works usually address individual recommendation tasks. There …

Nonprofit News, News Industrial Subsidies, And The Rise Of Citizen Journalism, Roger A. Lohmann

Faculty & Staff Scholarship

In this article three important policy questions are suggested in light of signs of recent growth of nonprofit news and the possibility of a great deal more similar growth in the future: 1) Does nonprofit news production pose a plausible solution to the economic troubles of the U.S. news industry? 2) Would industrial subsidies of nonprofits, like those for “welfare state” health and human services co-production offer a potential solution to the economic problems of the U.S. news industry? 3) Can the currently evolving internet-based system of news production by volunteer citizens be sustainable in the long run?

Walled Gardens: Privacy Within Public Leisure Space Online And Offline, Payal Arora

Payal Arora

Social network sites are the new urban parks where people congregate, socialize and exercise leisure. Its web architectures however are being walled in, dictated by market systems and State ideologies. These cyber-enclosures are justified along the lines of privacy that garners protection, efficiency and functionality. There is significant concern for the potential irrevocable loss of the ‘public’ and ‘open’ character intended of internet infrastructures, fearing the fostering of social segregation, homogenization and corporatization of leisure and a loss of civic sense. This paper addresses these concerns by looking at contemporary material architectures that are shaping public social and leisure space, …

A Probabilistic Graphical Model For Topic And Preference Discovery On Social Media, Lu Liu, Feida Zhu, Lei Zhang, Shiqiang Yang

Research Collection School Of Computing and Information Systems

Many web applications today thrive on offering services for large-scale multimedia data, e.g., Flickr for photos and YouTube for videos. However, these data, while rich in content, are usually sparse in textual descriptive information. For example, a video clip is often associated with only a few tags. Moreover, the textual descriptions are often overly specific to the video content. Such characteristics make it very challenging to discover topics at a satisfactory granularity on this kind of data. In this paper, we propose a generative probabilistic model named Preference-Topic Model (PTM) to introduce the dimension of user preferences to enhance the …

Enhancing Public Access To Online Rulemaking Information, Cary Coglianese

All Faculty Scholarship

One of the most significant powers exercised by federal agencies is their power to make rules. Given the importance of agency rulemaking, the process by which agencies develop rules has long been subject to procedural requirements aiming to advance democratic values of openness and public participation. With the advent of the digital age, government agencies have engaged in increasing efforts to make rulemaking information available online as well as to elicit public participation via electronic means of communication. How successful are these efforts? How might they be improved? In this article, I investigate agencies’ efforts to make rulemaking information available …

Putting Their Best Foot Forward: Emotional Disclosure On Facebook, Lin Qiu, Han Lin, Angela K. Y. Leung, William Tov

Research Collection School of Social Sciences

Facebook has become a widely used online self-representation and communication platform. In this research, we focus on emotional disclosure on Facebook. We conducted two studies, and results from both self-report and observer rating show that individuals are more likely to express positive relative to negative emotions and present better emotional well-being on Facebook than in real life. Our study is the first to demonstrate impression management on Facebook through emotional disclosure. We discuss important theoretical and practical implications of our study.

Influentials, Novelty, And Social Contagion: The Viral Power Of Average Friends, Close Communities, And Old News, Nicholas Harrigan, Palakorn Achananuparp, Ee Peng Lim

Research Collection School Of Computing and Information Systems

What is the effect of (1) popular individuals, and (2) community structures on the retransmission of socially contagious behavior? We examine a community of Twitter users over a five month period, operationalizing social contagion as ‘retweeting’, and social structure as the count of subgraphs (small patterns of ties and nodes) between users in the follower/following network. We find that popular individuals act as ‘inefficient hubs’ for social contagion: they have limited attention, are overloaded with inputs, and therefore display limited responsiveness to viral messages. We argue this contradicts the ‘law of the few’ and ‘influentials hypothesis’. We find that community …

Social Learning Theory In The Frontline Documentary “The Merchants Of Cool”, Alixe A. Wiley

Faculty Curated Undergraduate Works

In the Frontline documentary The Merchants of Cool, the relationship between major media conglomerates and their hedonistic teenage customers is examined through exploring the different tactics industries use to discover and market the next “cool” thing. Industries maintain what the documentary refers to as a “feedback loop” with their customers, which is a cyclic, supply-and-demand relationship that blurs the line between fiction and reality. It has become impossible to tell which side is imitating the other: who do the products and trends that define popular youth culture belong to? What's more, are the sexual and aggressive hormone-fueled behaviors on …

This article chronicles the attempts of one educational institution to implement the use of social media in their organisation.

Typology Of Web 2.0 Spheres: Understanding The Cultural Dimensions Of Social Media Spaces, Payal Arora

Payal Arora

It has taken the past decade to commonly acknowledge that online space is tethered to real place. From euphoric conceptualizations of social media spaces as a novel, unprecedented and revolutionary entity, the dust has settled, allowing for talk of boundaries and ties to real-world settings. Metaphors have been instrumental in this pursuit, shaping perceptions and affecting actions within this extended structural realm. Specifically, they have been harnessed to architect Web 2.0 spaces, be it chatrooms, electronic frontiers, homepages, or information highways for policy and practice. While metaphors are pervasive in addressing and normalizing new media spaces, there is less effort …

Preserving Social Media: Opening A Multi-Disciplinary Dialogue, Lisa P. Nathan, Elizabeth M. Shaffer

Elizabeth M. Shaffer

Digital artefacts generated through use of social media tools= have potential long-term value to individuals, organizations and societies. If there is a desire to systematically collect and preserve accounts of daily life, government activities, and societies’ documentary heritage, archival approaches must account for changing information systems—the tools, policies, and practices through which we engage in the contemporary information ecosystem. Through this paper we argue that in light of the growing complexity of digital information practices, particularly in relation to the use of social media, archivists need look to the scholarship of design and planning, in particular the work of human …

Cultural Differences And Switching Of In-Group Sharing Behavior Between An American (Facebook) And A Chinese (Renren) Social Networking Site, Lin Qiu, Han Lin, Angela K. Y. Leung

Ka Yee Angela LEUNG

Prior research has documented cultural dimensions that broadly characterize between-culture variations in Western and East Asian societies and that bicultural individuals can flexibly change their behaviors in response to different cultural contexts. In this article, we studied cultural differences and behavioral switching in the context of the fast emerging, naturally occurring online social networking, using both self-report measures and content analyses of online activities on two highly popular platforms, Facebook and Renren (the “Facebook of China”). Results showed that while Renren and Facebook are two technically similar platforms, the Renren culture is perceived as more collectivistic than the Facebook culture. …

Ambivalence And The Decision Tree, Kirby Farrell

kirby farrell

We are insolubly ambivalent creatures. Traditionally cultures have managed ambivalence by focusing on character and morality in motives. Freudian psychology recognized that cognitive conflict is insoluble and stressed equilibrium and grace in adaptation. Today technology's binary structure is complicating and sometimes superseding the traditional trope of character by organizing cognition around the trope of the decision tree.

Herding Cats, Knitting Fog, And Nailing Pudding To The Wall: Toward A Mixed-Methods Approach For Evaluating Social Media Marketing In Libraries, Selene Colburn

UVM Libraries Conference Day

Just a few years ago, social media tools were so new that adapters were considered innovators. Many academic libraries now routinely share information about their collections, programs, and services through these modalities, but how do we evaluate our efforts, in a medium that remains inherently experimental? This paper will look at both qualitative and quantitative evaluative measures that can be used together to assess the efficacy of social media marketing campaigns and will provide conference-goers with sample rubrics for assessing the use of Facebook, Twitter, and YouTube.

The sample for this study is limited to consumers with active accounts at online social networks such as Facebook or Twitter. Methodology is a three-part design. A multi-factor qualitative exploratory study (n=73) reveals four celebrity-consumer relationships whose proposed measurement scales are tested in a quantitative pilot study (n=85). Finally, a large sample study (n=593) is used to test the measurement model and to test the proposed …

Book Review: The Ethics Of Emerging Media: Information, Social Norms And New Media Technology, Sue Burzynski Bullard

College of Journalism and Mass Communications: Faculty Publications

Discussions of new media and ethics sometimes include the notion that “ethics are ethics”—that doing the right thing is, and has been, a constant over time and across media.

The idea has a certain appeal. But it gets new twists in The Ethics of Emerging Media, by Bruce E. Drushel and Kathleen German, assistant professors of communication at Miami University. New media create new ethical questions and opportunities to cross ethical lines, as the thirteen contributors to this collection examine.

The Marketing Effectiveness Of Hotel Facebook Pages: From Perspectives Of Customers And Messages, Xi Yu Leung

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the hotel industry, social media marketing has become a new trend hoteliers are chasing and an increasing number of hotels are using social media to promote their business. However, the marketing effectiveness of social media is still a big challenge in both academic and business world. Since social media marketing is totally different from traditional marketing approaches, traditional marketing theories and practices may not be applicable to social media. Besides, very few studies have examined the effectiveness of social media marketing in the academic world.

Therefore, this study intended to provide an in-depth examination on the marketing effectiveness of …

By building on the previously published research of Altuna and Konuk (2009), this work investigates the attitudes and behavioral intentions toward mobile marketing of Generation Y consumers in the United States, France, and China. Based on this analysis, Chinese Gen Y have the most positive attitude toward mobile marketing, and their overall attitude is significantly more positive than the attitudes of French and American Gen Y groups. While American Gen Y's behavioral intentions are …

When Antitrust Met Facebook, Christopher S. Yoo

All Faculty Scholarship

Social networks are among the hottest phenomena on the Internet. Facebook eclipsed Google as the most visited website in both 2010 and 2011. Moreover, according to Nielsen estimates, as of the end of 2011 the average American spent nearly seven hours per month on Facebook, which is more time than they spent on Google, Yahoo!, YouTube, Microsoft, and Wikipedia combined. LinkedIn’s May 19, 2011 initial public offering (“IPO”) surpassed expectations, placing the value of the company at nearly $9 billion, and approximately a year later, its stock price had risen another 20 percent. Facebook followed suit a year later with …

Detecting Anomalous Twitter Users By Extreme Group Behaviors, Hanbo Dai, Ee-Peng Lim, Feida Zhu, Hwee Hwa Pang

Research Collection School Of Computing and Information Systems

Twitter has enjoyed tremendous popularity in the recent years. To help categorizing and search tweets, Twitter users assign hashtags to their tweets. Given that hashtag assignment is the primary way to semantically categorizing and search tweets, it is highly susceptible to abuse by spammers and other anomalous users [1]. Popular hashtags such as #Obama and #ladygaga could be hijacked by having them added to unrelated tweets with the intent of misleading many other users or promoting specific agenda to the users. The users performing this act are known as the hashtag hijackers. As the hijackers usually abuse common sets of …

Topic Discovery From Tweet Replies, Bingtian Dai, Ee Peng Lim, Philips Kokoh Prasetyo

Research Collection School Of Computing and Information Systems

Twitter is a popular online social information network service which allows people to read and post messages up to 140 characters, known as “tweets”. In this paper, we focus on the tweets between pairs of individuals, i.e., the tweet replies, and propose a generative model to discover topics among groups of twitter users. Our model has then been evaluated with a tweet dataset to show its effectiveness.

Finding Bursty Topics From Microblogs, Qiming Diao, Jing Jiang, Feida Zhu, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Microblogs such as Twitter reflect the general public’s reactions to major events. Bursty topics from microblogs reveal what events have attracted the most online attention. Although bursty event detection from text streams has been studied before, previous work may not be suitable for microblogs because compared with other text streams such as news articles and scientific publications, microblog posts are particularly diverse and noisy. To find topics that have bursty patterns on microblogs, we propose a topic model that simultaneousy captures two observations: (1) posts published around the same time are more likely to have the same topic, and (2) …

When A Friend In Twitter Is A Friend In Life, Wei Xie, Cheng Li, Feida Zhu, Ee-Peng Lim, Xueqing Gong

Research Collection School Of Computing and Information Systems

Twitter is a fast-growing online social network service (SNS) where users can "follow" any other user to receive his or her mini-blogs which are called "tweets". In this paper, we study the problem of identifying a user's off-line real-life social community, which we call the user'sTwitter off-line community, purely from examining Twitter network structure. Based on observations from our user-verified Twitter data and results from previous works, we propose three principles about Twitter off-line communities. Incorporating these principles, we develop a novel algorithm to iteratively discover the Twitter off-line community based on a new way of measuring user closeness. According …
