On Predicting Religion Labels In Microblogging Networks, Minh Thap Nguyen, Ee Peng Lim
On Predicting Religion Labels In Microblogging Networks, Minh Thap Nguyen, Ee Peng Lim
Research Collection School Of Computing and Information Systems
Religious belief plays an important role in how people behave, influencing how they form preferences, interpret events around them, and develop relationships with others. Traditionally, the religion labels of user population are obtained by conducting a large scale census study. Such an approach is both high cost and time consuming. In this paper, we study the problem of predicting users' religion labels using their microblogging data. We formulate religion label prediction as a classification task, and identify content, structure and aggregate features considering their self and social variants for representing a user. We introduce the notion of representative user to …
Impact Of Social Media On Power Relations Of Korean Health Activism, Kyu Jin Shim
Impact Of Social Media On Power Relations Of Korean Health Activism, Kyu Jin Shim
Research Collection Lee Kong Chian School Of Business
This case study explores how the Korea Leukemia Patient Group (KLPG) uses social media in its internal communication strategy and how that empowers its relationship with external counterparts. The findings of this study indicate that the local health NGO’s communication strategy is changing in response to the increased effectiveness and impact of social media. With the use of social media like Twitter, the KLPG can construct an issue-based advocacy group quickly and effectively. Consequently, more legitimacy and representativeness through collected support from general publics has further empowered the KLPG. Yet, the sustainability component in the relationships built through social media …
Lifetime Lexical Variation In Social Media, Lizi Liao, Jing Jiang, Ying Ding, Heyan Huang, Ee Peng Lim
Lifetime Lexical Variation In Social Media, Lizi Liao, Jing Jiang, Ying Ding, Heyan Huang, Ee Peng Lim
Research Collection School Of Computing and Information Systems
As the rapid growth of online social media attracts a large number of Internet users, the large volume of content generated by these users also provides us with an opportunity to study the lexical variation of people of different ages. In this paper, we present a latent variable model that jointly models the lexical content of tweets and Twitter users’ ages. Our model inherently assumes that a topic has not only a word distribution but also an age distribution. We propose a Gibbs-EM algorithm to perform inference on our model. Empirical evaluation shows that our model can learn meaningful age-specific …

Parasocial Relationship Via Reality Tv And Social Media: Its Implications For Celebrity Endorsement, Siyoung Chung, Hichang Cho
Parasocial Relationship Via Reality Tv And Social Media: Its Implications For Celebrity Endorsement, Siyoung Chung, Hichang Cho
Research Collection Lee Kong Chian School Of Business
The purpose of this study was to explore the ways in which audiences build parasocial relationships with media characters via reality TV and social media, and its implications for celebrity endorsement and purchase intentions. Using an online survey, this study collected 401 responses from the Korean Wave fans in Singapore. The results showed that reality TV viewing and SNS use to interact with media characters were positively associated with parasocial relationships between media characters and viewers. Parasocial relationships, in turn, were positively associated with the viewers’ perception of endorser and brand credibility, and purchase intention of the brand endorsed by …

Online Community Transition Detection, Biying Tan, Feida Zhu, Qiang Qu, Siyuan Liu
Research Collection School Of Computing and Information Systems
Mining user behavior patterns in social networks is of great importance in user behavior analysis, targeted marketing, churn prediction and other applications. However, less effort has been made to study the evolution of user behavior in social communities. In particular, users join and leave communities over time. How to automatically detect the online community transitions of individual users is a research problem of immense practical value yet with great technical challenges. In this paper, we propose an algorithm based on the Minimum Description Length (MDL) principle to trace the evolution of community transition of individual users, adaptive to the noisy …

Socio-Physical Analytics: Challenges & Opportunities, Archan Misra, Kasthuri Jayarajah, Shriguru Nayak, Philips Kokoh Prasetyo, Ee-Peng Lim
Research Collection School Of Computing and Information Systems
In this paper, we argue for expanded research into an area called Socio-Physical Analytics, that focuses on combining the behavioral insight gained from mobile-sensing based monitoring of physical behavior with the inter-personal relationships and preferences deduced from online social networks. We highlight some of the research challenges in combining these heterogeneous data sources and then describe some examples of our ongoing work (based on real-world data being collected at SMU) that illustrate two aspects of socio-physical analytics: (a) how additional demographic and online analytics based attributes can potentially provide better insights into the preferences and behaviors of individuals or groups …
Does Latitude Hurt While Longitude Kills? Geographical And Temporal Separation In A Large Scale Software Development Project, Patrick Wagstrom, Subhajit Datta
Does Latitude Hurt While Longitude Kills? Geographical And Temporal Separation In A Large Scale Software Development Project, Patrick Wagstrom, Subhajit Datta
Research Collection School Of Computing and Information Systems
Distributed software development allows firms to leverage cost advantages and place work near centers of competency. This distribution comes at a cost -- distributed teams face challenges from differing cultures, skill levels, and a lack of shared working hours. In this paper we examine whether and how geographic and temporal separation in a large scale distributed software development influences developer interactions. We mine the work item trackers for a large commercial software project with a globally distributed development team. We examine both the time to respond and the propensity of individuals to respond and find that when taken together, geographic …
Seeking Information About Climate Change: Effects Of Media Use In An Extended Prism, Shirley S. Ho, Benjamin H. Detenber, Sonny Rosenthal, Edmund W. J. Lee
Seeking Information About Climate Change: Effects Of Media Use In An Extended Prism, Shirley S. Ho, Benjamin H. Detenber, Sonny Rosenthal, Edmund W. J. Lee
Research Collection College of Integrative Studies
This study replicates and extends the planned risk information seeking model (PRISM) in the context of impersonal risk by incorporating media use as an antecedent of risk information seeking intention. Results indicate that the model applies equally well to Singaporeans’ climate change information seeking intention as it does in the context of personal health information, suggesting that the model is generalizable across different risk and cultural contexts. Findings suggest that media use is an important source of perceived knowledge and, indirectly, sufficiency threshold, which clarifies the role of actual information seeking in risk perceptions and future information seeking.
Media Frames And Cognitive Accessibility: What Do "Global Warming" And "Climate Change" Evoke Partisan Minds?, Jonathon P. Schuldt, Sungjong Roh
Media Frames And Cognitive Accessibility: What Do "Global Warming" And "Climate Change" Evoke Partisan Minds?, Jonathon P. Schuldt, Sungjong Roh
Research Collection Lee Kong Chian School Of Business
Decades of research demonstrate that how the public thinks about a given issue is affected by how it is framed by the media. Typically, studies of framing vary how an issue is portrayed (often, by altering the text of written communication) and compare subsequent beliefs, attitudes, or preferences—taking a framing effect as evidence that a media frame (or frame in communication) instantiated a particular audience frame (or frame in thought). Less work, however, has attempted to measure frames in thought directly, which may illuminate cognitive mechanisms that underlie framing effects. In this vein, we describe a Web experiment (n = …
On Modeling Community Behaviors And Sentiments In Microblogging, Tuan Anh Hoang, William Cohen, Ee Peng Lim
On Modeling Community Behaviors And Sentiments In Microblogging, Tuan Anh Hoang, William Cohen, Ee Peng Lim
Research Collection School Of Computing and Information Systems
In this paper, we propose the CBS topic model, a probabilistic graphical model, to derive the user communities in microblogging networks based on the sentiments they express on their generated content and behaviors they adopt. As a topic model, CBS can uncover hidden topics and derive user topic distribution. In addition, our model associates topic-specific sentiments and behaviors with each user community. Notably, CBS has a general framework that accommodates multiple types of behaviors simultaneously. Our experiments on two Twitter datasets show that the CBS model can effectively mine the representative behaviors and emotional topics for each community. We also …

Do You Know The Speaker?: An Online Experiment With Authority Messages On Event Websites, Kwan-Hui Lim, Binyan Jiang, Ee Peng Lim, Achananuparp Palakorn
Research Collection School Of Computing and Information Systems
With the widespread adoption of the Web, many companies and organizations have established websites that provide information and support online transactions (e.g., buying products or viewing content). Unfortunately, users have limited attention to spare for interacting with online sites. Hence, it is of utmost importance to design sites that attract user attention and effectively guide users to the product or content items they like. Thus, we propose a novel and scalable experimentation approach to evaluate the effectiveness of online site designs. Our case study focuses on the effects of an authority message on visitors' browsing behavior on workshop and seminar …

Recurrent Chinese Restaurant Process With A Duration-Based Discount For Event Identification From Twitter, Qiming Diao, Jing Jiang
Recurrent Chinese Restaurant Process With A Duration-Based Discount For Event Identification From Twitter, Qiming Diao, Jing Jiang
Research Collection School Of Computing and Information Systems
Due to the fast development of social media on the Web, Twitter has become one of the major platforms for people to express themselves. Because of the wide adoption of Twitter, events like breaking news and release of popular videos can easily catch people’s attention and spread rapidly on Twitter, and the number of relevant tweets approximately reflects the impact of an event. Event identification and analysis on Twitter has thus become an important task. Recently the Recurrent Chinese Restaurant Process (RCRP) has been successfully used for event identification from news streams and news-centric social media streams. However, these models …

Social Correlation In Latent Spaces For Complex Networks, Freddy Chong Tat Chua
Social Correlation In Latent Spaces For Complex Networks, Freddy Chong Tat Chua
Dissertations and Theses Collection (Open Access)
This dissertation addresses the subject of measuring social correlation among users within a complex social network. Social correlation is closely related to the measurement of social influence in social sciences. While social influence focuses on the existence of causal influence among users, we take a computational approach to measure correlation strength among users based on their shared interactions. We call this social correlation. To formally model social correlation, we propose a framework which contains two major parts. The first part is that of representing users behavior in a computationally efficient and accurate manner. For example, social media users perform many …

Changing Views On Media Ethics And Societal Functions Among Students In Singapore, Benjamin Hill Detenber, Sonny Rosenthal
Changing Views On Media Ethics And Societal Functions Among Students In Singapore, Benjamin Hill Detenber, Sonny Rosenthal
Research Collection College of Integrative Studies
This panel study assessed changes in ethical ideology and beliefs about the societal function of media over the course of undergraduate communication education in Singapore. First, students' agreement with the ethical principles of truth telling, independence, and accountability increased. Second, change in agreement with the ethical principle of minimizing harm was negatively related to change in justification of contentious newsgathering methods. Third, belief that the media should function as a watchdog increased and that it should serve national development decreased. Change in these variables was inversely correlated. We relate these findings to global contexts and make recommendations for curriculum development.

In 2009, U.S. Congress approved $7.2. billion to accelerate the deployment of advanced broadband networks and services to unserved and underserved regions of the country. Although primarily a short-term response to the economic crisis, the appropriation also indicates a willingness to seek a new balance between private sector and public sector initiatives in the development of the nation's broadband infrastructure. This paper is a first step in assessing the potential impact of the new government initiatives. It discusses in detail one component of the overall program, the Broadband Technology Opportunities Program (BTOP). The rationales and objectives of BTOP and its …
