Whole-Of-Society Approach Needed Against Truth Decay, Eugene K. B. Tan Nov 2018

Whole-Of-Society Approach Needed Against Truth Decay, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

In an age of pervasive informationflows, governments do not defeat fake news. It's the people as a society whodo.The threatof deliberate falsehoods, or more popularly "fake news", posesserious threats to the democratic wellbeing of societies. The marketplace ofideas increasingly suffers from truth decay, propagated online or offline,imperilling an already vulnerable information ecosystem. In turn,this compromises the functioning of a democracy, which is premised on citizenshaving a shared reality rather than multiple distorted realities.

Implicit Linking Of Food Entities In Social Media, Wen Haw Chong, Ee Peng Lim Sep 2018

Implicit Linking Of Food Entities In Social Media, Wen Haw Chong, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Dining is an important part in people’s lives and this explains why food-related microblogs and reviews are popular in social media. Identifying food entities in food-related posts is important to food lover profiling and food (or restaurant) recommendations. In this work, we conduct Implicit Entity Linking (IEL) to link food-related posts to food entities in a knowledge base. In IEL, we link posts even if they do not contain explicit entity mentions. We first show empirically that food venues are entity-focused and associated with a limited number of food entities each. Hence same-venue posts are likely to share common food …

Diversity In Online Advertising: A Case Study Of 69 Brands On Social Media, Jisun An, Ingmar Weber Sep 2018

Diversity In Online Advertising: A Case Study Of 69 Brands On Social Media, Jisun An, Ingmar Weber

Research Collection School Of Computing and Information Systems

Lack of diversity in advertising is a long-standing problem. Despite growing cultural awareness and missed business opportunities, many minorities remain under- or inappropriately represented in advertising. Previous research has studied how people react to culturally embedded ads, but such work focused mostly on print media or television using lab experiments. In this work, we look at diversity in content posted by 69 U.S. brands on two social media platforms, Instagram and Facebook. Using face detection technology, we infer the gender, race, and age of both the faces in the ads and of the users engaging with ads. Using this dataset, …

Context Recovery In Location-Based Social Networks, Wen Haw Chong Jul 2018

Context Recovery In Location-Based Social Networks, Wen Haw Chong

Dissertations and Theses Collection (Open Access)

This dissertation addresses context recovery in Location-Based Social Networks (LBSN), which are platforms where users post content from various locations. With this general LBSN definition, many existing social media platforms that support user-generated location relevant content using mobile devices could also qualify as LBSNs. Context recovery for such user posts refers to recovering the venue and the semantic contexts of these user posts. Such information is useful for user profiling and to support various applications such as venue recommendation and location- based advertising.

Exploring Offline Friendships On The Social Information Network: Network Characteristics, Information Diffusion, And Tie Strength, Felicia Natali Jul 2018

Exploring Offline Friendships On The Social Information Network: Network Characteristics, Information Diffusion, And Tie Strength, Felicia Natali

Dissertations and Theses Collection (Open Access)

The rapid increase in online social networking services over the last decade has pre- sented an unprecedented opportunity to observe users’ behaviour both on a societal and individual level. The insight gained from analysing such data can help foster a deeper understanding of social media users and the flow of information, while also offering valuable business applications. User relationships are among the most studied aspects of online behaviour. These relationships are not homogeneous. Past research has shown that people use social networks to both socialize and source in- formation. Hence, different types of links – used to socialize, gain information, …

Detecting Personal Intake Of Medicine From Twitter, Debanjan Mahata, Jasper Friedrichs, Rajiv Ratn Shah, Jing Jiang

Research Collection School Of Computing and Information Systems

Mining social media messages such as tweets, blogs, and Facebook posts for health and drug related information has received significant interest in pharmacovigilance research. Social media sites (e.g., Twitter), have been used for monitoring drug abuse, adverse reactions to drug usage, and analyzing expression of sentiments related to drugs. Most of these studies are based on aggregated results from a large population rather than specific sets of individuals. In order to conduct studies at an individual level or specific groups of people, identifying posts mentioning intake of medicine by the user is necessary. Toward this objective we develop a classifier …

Government Intervention In Corporate Crises: An Asian Perspective, Augustine Pang, Paige Pei-Hua Tan Jul 2018

Government Intervention In Corporate Crises: An Asian Perspective, Augustine Pang, Paige Pei-Hua Tan

Research Collection Lee Kong Chian School Of Business

Governments are expected to intervene in national crises like natural disasters (Rosenthal & Kouzmin, 1997). Less clear are corporate crises. In recent years, there have been several corporate crises in Asia where governments have intervened to restore confidence. The paper seeks to examine the roles and extent of Asian governmental intervention in corporate crises, particularly it examines the impact Asian governments – described as paternalistic (Shin & Sin, 2012) – have on corporate crises. Five high profile Asian corporate crises were analyzed through Winkler’s (1977) Theory of Corporatism. Impact was analyzed through Boin and ’t Hart’s (2010) nine crisis response …

Pacela: A Neural Framework For User Visitation In Location-Based Social Networks, Thanh Nam Doan, Ee-Peng Lim Jul 2018

Pacela: A Neural Framework For User Visitation In Location-Based Social Networks, Thanh Nam Doan, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Check-in prediction using location-based social network data is an important research problem for both academia and industry since an accurate check-in predictive model is useful to many applications, e.g. urban planning, venue recommendation, route suggestion, and context-aware advertising. Intuitively, when considering venues to visit, users may rely on their past observed visit histories as well as some latent attributes associated with the venues. In this paper, we therefore propose a check-in prediction model based on a neural framework called Preference and Context Embeddings with Latent Attributes (PACELA). PACELA learns the embeddings space for the user and venue data as well …

From 2,772 Segments To Five Personas: Summarizing A Diverse Online Audience By Generating Culturally Adapted Personas, Joni Salminen, Sercan Sengun, Haewoon Kwak, Bernard J. Jansen, Jisun An, Soon-Gyu Jung, Sarah Vieweg, D. Fox Harrell

Research Collection School Of Computing and Information Systems

Understanding users in the era of social media is challenging, requiring organizations to adopt novel computation-aided approaches. To exemplify such an approach, we retrieved information on millions of interactions with YouTube video content from a major Middle Eastern media outlet, to automatically generate personas that capture how different audience segments interact with thousands of individual content pieces. Then, we used qualitative data to provide additional insights into the automatically generated persona profiles. Our findings provide insights into social media usage in the Middle East and demonstrate the application of a novel methodology that generates culturally adapted personas of social media …

Efficacy Beliefs In Third-Person Effects, Sonny Rosenthal, Benjamin H. Detenber, Hernando Rojas Jun 2018

Efficacy Beliefs In Third-Person Effects, Sonny Rosenthal, Benjamin H. Detenber, Hernando Rojas

Research Collection College of Integrative Studies

People generally believe they are less susceptible than others to influences of media, and a growing body of research implicates such biased processing, or third-person perception, in public support for censorship, a type of third-person effect. The current study extends research of the third-person effect by studying two efficacy-related concepts in the context of sexual content in films. Analysis of cross-sectional data from 1,012 Singaporeans suggests that people exhibit self-other asymmetries of efficacy beliefs: They believe others are less capable than they are of self-regulation and that censorship is more effective at restricting others’ access to sexual content in films. …

When Secular Universalism Meets Pluralism: Religious Schools And The Politics Of School-Based Management In Hong Kong, Junxi Qian, Lily Kong May 2018

When Secular Universalism Meets Pluralism: Religious Schools And The Politics Of School-Based Management In Hong Kong, Junxi Qian, Lily Kong

Research Collection School of Social Sciences

This article examines the politics of school-based management (SBM) in Hong Kong, with a specific focus on the conflicts between the state and three Christian churches (Catholic, Anglican, and Methodist) running state-funded religious schools. Although the state based its advocacy for SBM on neoliberally driven ideas of participation, transparency, and accountability, religious groups expressed worry about the loss of control over schools as an institution of value transmission anchored in religious beliefs. This article uses the SBM controversy as a case study to advance geographical debates on religious schools and argues that neoliberalism forms a necessary lens through which to …

Is All Politics Local? Determinants Of Local And National Election Campaigns, Colm A. Fox May 2018

Is All Politics Local? Determinants Of Local And National Election Campaigns, Colm A. Fox

Research Collection School of Social Sciences

In recent decades election campaigns have shifted their focus from the local to the national level, increasingly featuring party leaders, labels, and national platforms. Despite this trend, there remains significant variation in the local/national orientation of campaigns across countries and parties. This article tests several propositions on why campaigns adopt a local or national orientation by analyzing a unique collection of more than 12,000 geocoded Thai election posters. Specialized software was used to measure the spatial proportions of visual and textual content on each poster. Using Thailand’s mixed electoral system to enable a controlled comparison of electoral rules, I demonstrate …

Unpacking Public Sentiment Toward The Government: How Citizens’ Perceptions Of Government Communication Strategies Impact Public Engagement, Cynicism, And Communication Behaviors In South Korea, Soojin Kim, Arunima Krishna

Research Collection Lee Kong Chian School Of Business

In this study, we explore the relationship between two types of public sentiment toward the government (i.e., public engagement and cynicism) on publics’ information transmission behaviors, i.e., megaphoning, about the government. In doing so, we unpack how citizens’ perceptions of the communication strategy adopted by the government, as well perceived authenticity of the government’s communication impact their sentiments toward the government. An online survey was conducted in South Korea (N = 1112) to understand these relationships. The results revealed that perceived use of bridging strategy by the government is associated with public engagement, and perceived use of the buffering strategy …

Learning Latent Characteristics Of Locations Using Location-Based Social Networking Data, Thanh Nam Doan May 2018

Learning Latent Characteristics Of Locations Using Location-Based Social Networking Data, Thanh Nam Doan

Dissertations and Theses Collection (Open Access)

This dissertation addresses the modeling of latent characteristics of locations to describe the mobility of users of location-based social networking platforms. With many users signing up location-based social networking platforms to share their daily activities, these platforms become a gold mine for researchers to study human visitation behavior and location characteristics. Modeling such visitation behavior and location characteristics can benefit many use- ful applications such as urban planning and location-aware recommender sys- tems. In this dissertation, we focus on modeling two latent characteristics of locations, namely area attraction and neighborhood competition effects using location-based social network data. Our literature survey …

Discovering Hidden Topical Hubs And Authorities In Online Social Networks, Roy Ka-Wei Lee, Tuan-Anh Hoang, Ee-Peng Lim May 2018

Discovering Hidden Topical Hubs And Authorities In Online Social Networks, Roy Ka-Wei Lee, Tuan-Anh Hoang, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Finding influential users in online social networks is an important problem with many possible useful applications. HITS and other link analysis methods, in particular, have been often used to identify hub and authority users in web graphs and online social networks. These works, however, have not considered topical aspect of links in their analysis. A straightforward approach to overcome this limitation is to first apply topic models to learn the user topics before applying the HITS algorithm. In this paper, we instead propose a novel topic model known as Hub and Authority Topic (HAT) model to combines the two process …

Advice Giving: A Subtle Pathway To Power, Michael Schaerer, Leigh Tost, Li Huang, Francesca Gino, Rick Larrick May 2018

Advice Giving: A Subtle Pathway To Power, Michael Schaerer, Leigh Tost, Li Huang, Francesca Gino, Rick Larrick

Research Collection Lee Kong Chian School Of Business

We propose that interpersonal behaviors can activate feelings of power, and we examine this idea in the context of advice giving. Specifically, we show a) that advice giving is an interpersonal behavior that enhances individuals’ sense of power and b) that those who seek power are motivated to engage in advice giving. Four studies, including two experiments (n=290, n=188), an organization-based field study (n=94), and a negotiation simulation (n=124) demonstrate that giving advice enhances the advisor’s sense of power because it gives the advisor perceived influence over others’ actions. Two of our studies further demonstrate that people with a high …

Research Collection School Of Computing and Information Systems

Over the past few years, a number of new "fringe" communities, like 4chan or certain subreddits, have gained traction on the Web at a rapid pace. However, more often than not, little is known about how they evolve or what kind of activities they attract, despite recent research has shown that they influence how false information reaches mainstream communities. This motivates the need to monitor these communities and analyze their impact on the Web's information ecosystem. In August 2016, a new social network called Gab was created as an alternative to Twitter. It positions itself as putting "people and free …

Detect Rumor And Stance Jointly By Neural Multi-Task Learning, Jing Ma, Wei Gao, Kam-Fai Wong Apr 2018

Detect Rumor And Stance Jointly By Neural Multi-Task Learning, Jing Ma, Wei Gao, Kam-Fai Wong

Research Collection School Of Computing and Information Systems

In recent years, an unhealthy phenomenon characterized as the massive spread of fake news or unverified information (i.e., rumors) has become increasingly a daunting issue in human society. The rumors commonly originate from social media outlets, primarily microblogging platforms, being viral afterwards by the wild, willful propagation via a large number of participants. It is observed that rumorous posts often trigger versatile, mostly controversial stances among participating users. Thus, determining the stances on the posts in question can be pertinent to the successful detection of rumors, and vice versa. Existing studies, however, mainly regard rumor detection and stance classification as …

Exploiting User And Venue Characteristics For Fine-Grained Tweet Geolocation, Wen Haw Chong, Ee Peng Lim Apr 2018

Exploiting User And Venue Characteristics For Fine-Grained Tweet Geolocation, Wen Haw Chong, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Which venue is a tweet posted from? We call this a fine-grained geolocation problem. Given an observed tweet, the task is to infer its discrete posting venue, e.g., a specific restaurant. This recovers the venue context and differs from prior work, which geolocats tweets to location coordinates or cities/neighborhoods. First, we conduct empirical analysis to uncover venue and user characteristics for improving geolocation. For venues, we observe spatial homophily, in which venues near each other have more similar tweet content (i.e., text representations) compared to venues further apart. For users, we observe that they are spatially focused and more likely …

Do Your Friends Make You Buy This Brand?: Modeling Social Recommendation With Topics And Brands, Minh Duc Luu, Ee Peng Lim Mar 2018

Do Your Friends Make You Buy This Brand?: Modeling Social Recommendation With Topics And Brands, Minh Duc Luu, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Consumer behavior and marketing research have shown that brand has significant influence on product reviews and product purchase decisions. However, there is very little work on incorporating brand related factors into product recommender systems. Meanwhile, the similarity in brand preference between a user and other socially connected users also affects her adoption decisions. To integrate seamlessly the individual and social brand related factors into the recommendation process, we propose a novel model called Social Brand–Item–Topic (SocBIT). As the original SocBIT model does not enforce non-negativity, which poses some difficulty in result interpretation, we also propose a non-negative version, called SocBIT(Formula …

Public Support For Censorship In A Highly Regulated Media Environment: The Influence Of Self-Construal And Third-Person Perception Over Time, Benjamin H. Detenber, Sonny Rosenthal Mar 2018

Public Support For Censorship In A Highly Regulated Media Environment: The Influence Of Self-Construal And Third-Person Perception Over Time, Benjamin H. Detenber, Sonny Rosenthal

Research Collection College of Integrative Studies

This study represents the first longitudinal examination of third-person effects and uses a rigorous specification of the relative contribution of perceptions of influence on self and others (viz., the diamond method). Using nationally representative samples from Singapore gathered in 2001 (n = 626) and 2013 (n = 1,012), it examines perceptions of sex and nudity in films, content that the government allows but regulates. As expected, interdependent self-construal and third-person perceptions predicted support for censorship, as did perceived total media influence. The pattern of prediction was quite consistent with a slight increase in support for censorship. The discussion considers implications …

Public Understanding Of One Health Messages: The Role Of Temporal Framing, Sungjong Roh, Laura N. Rickard, Katherine A. Mccomas, Daniel J. Decker

Research Collection Lee Kong Chian School Of Business

Building on research in motivated reasoning and framing in science communication, we examine how messages that vary attribution of responsibility (human vs animal) and temporal orientation (now vs in the next 10 years) for wildlife disease risk influence individuals’ conservation intentions. We conducted a randomized experiment with a nationally representative sample of US adults (N = 355), which revealed that for people low in biospheric concern, messages that highlighted both human responsibility for and the imminent nature of the risk failed to enhance conservation intentions compared with messages highlighting animal responsibility. However, when messages highlighting human responsibility placed the risk …
