Designing Microblogging-Based Class Activities, Tian Luo, Fei Gao

STEMPS Faculty Publications

Microblogging tools such as Twitter have been frequently adopted in educational settings to facilitate learning. This study examined how a microblogging tool, Twiducate, was incorporated into a graduate-level class of ten students. During the 1.5 hour lesson, students participated in a series of Twiducate-supported collaborative and reflective activities. The analysis of in-class discussion transcripts, text-based posts on Twiducate and a pre- and post-test survey results revealed that students were highly engaged in classroom collaborative learning and there is a high level of interaction. Students reported the challenges of using microblogging tools, such as the possibility of creating distraction and disorder …

On The Origins Of The Cute As A Dominant Aesthetic Category In Digital Culture, Dylan E. Wittkower

Philosophy Faculty Publications

In discussions of online culture, nobody has yet given sufficient consideration to the importance of cute animal pictures. While there are perhaps obvious reasons for this aspect of online culture being and remaining understudied, from an objective stance we should consider it both surprising and noteworthy that, once given the means of mass communications and internationally accessible publication, a primary activity that people are interested in and committed to is the sharing of cute and funny pictures, especially of cats. This presumably unforeseeable outcome is made stranger yet by the relative lack of commercial motivation for a communications category that …

"Friend" Is A Verb, Dylan E. Wittkower

Philosophy Faculty Publications

An argument against the Aristotelian emphasis on formal and final causes in understanding friendship, and in favor of efficient and material causes. Attempts to establish that social media communications constitute a secondary literacy in the context of a shared asynchronous experience at a distance, and addresses "the sandwich problem:" how we can charitably account for the practice of photographing and sharing one's lunch.

"You Got To Be Follow-Worthy Or I Will Unfollow You!” Students’ Voices On Twitter Integration Into Classroom Settings, Tian Luo, Teresa Franklin

STEMPS Faculty Publications

This research centers on a case study where Twitter was integrated in an undergraduate level course. Under the instructor’s specific guidance and ongoing feedback, students actively participate in the course both in and outside of classroom. They perceived the incorporation of Twitter into classroom to be highly engaging and contributive to their learning. During the 10 week course, students’ initiatives in developing self-defined codes of conduct for tweeting, creating user groups, and assisting one another to become proficient in using Twitter, demonstrated a high degree of autonomous social learning in both formal and informal learning environments. Not only were they …

Facebooking In Distance Education: Constructing Virtual Communities Of Practice, Virginia M. Tucker

English Faculty Publications

The growth of distance education warrants a closer look at how virtual communities of practice form in asynchronous online classrooms. Prior studies have sought to identify a process to virtual community formation, which may vary depending upon the media used for collaboration. This microstudy examines how one student group in a distance writing course used the popular social media site Facebook to construct community and whether the stages of virtual community development were observed in this setting. Findings suggest that revisions might be made to our current understanding of the process of building virtual community within small groups. “Othering” and …

Haptics-Augmented Training Software For Undergraduate Engineering Mechanics, Ernur Karadogan, Robert L. Williams, David R. Moore, Tian Luo

STEMPS Faculty Publications

This paper presents the development efforts for a set of software activities and tutorials to augment teaching and learning in standard required undergraduate engineering mechanics courses. Using these software activities, students can change parameters, predict answers, compare outcomes, interact with animations, and feel the results. The overall system aims to increase teaching and learning effectiveness by rendering the concepts compelling, fun, and engaging. The problem with current examples and homework problems is that they are flat, static, boring, and non-engaging, which may lead to student attrition and a less than full grasp of fundamental principles. We implement integration of haptics …

Predictive Modeling For Navigating Social Media, Meiqun Hu

Dissertations and Theses Collection (Open Access)

Social media changes the way people use the Web. It has transformed ordinary Web users from information consumers to content contributors. One popular form of content contribution is social tagging, in which users assign tags to Web resources. By the collective efforts of the social tagging community, a new information space has been created for information navigation. Navigation allows serendipitous discovery of information by examining the information objects linked to one another in the social tagging space. In this dissertation, we study prediction tasks that facilitate navigation in social tagging systems. For social tagging systems to meet complex navigation needs …

Enhancing Classroom Learning Experience By Providing Structures To Microblogging-Based Activities, Tian Luo, Fei Gao

STEMPS Faculty Publications

Microblogging tools such as Twitter have been frequently adopted in educational settings to facilitate learning in recent years. Although the original purpose of microblogging tools is to connect with others in a wide network and instantly share what is happening to them with the rest of the world, educators have vigorously attempted to repurpose the utilization of the tool and integrate it into various educational settings to promote student learning.

The purpose of this study is to examine student learning experience under a set of structured microblogging-based activities and to identify the affordances and constraints of the technology. Students participated …

Digital Video: Engaging Students In Critical Media Literacy And Community Activism, Jessie Daniels

Publications and Research

This article presents a strategy for teaching health communication that fosters critical media literacy through the strategic combination of digital video, documentary film, video worksheets, and peer-reviewed journal articles. Given the media-saturated environment in which notions of health are shaped, critical media literacy skills are crucial to students in health-related fields. Cases of key concepts illustrated through documentary films and the peer-reviewed literature are presented. The article then explores how one class took the lead in designing a community event that critically engaged both a YouTube video and a documentary film about police brutality as a public health issue.

Our primary research revealed that these individuals turn first to eye care professionals, resource organizations for the visually impaired and residential …

Content Contribution Under Revenue Sharing And Reputation Concern In Social Media: The Case Of Youtube, Qian Tang, Bin Gu, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

A key feature of social media is that it allows individuals and businesses to contribute contents for public viewing. However, little is known about how content providers derive payoffs from such activities. In this study, we build a dynamic structural model to recover the utility function for content providers. Our model distinguishes short-term payoffs based on ad revenue sharing from long-term payoffs driven by content providers’ reputation. The model was estimated using a panel data of 914 top 1000 providers and 381 randomly selected providers on YouTube from Jun 7th, 2010, to Aug 7th, 2011. The two different sets of …

Modeling Social Strength In Social Media Community Via Kernel-Based Learning, Jinfeng Zhuang, Tao Mei, Steven C. H. Hoi, Xian-Sheng Hua, Shipeng Li

Research Collection School Of Computing and Information Systems

Modeling continuous social strength rather than conventional binary social ties in the social network can lead to a more precise and informative description of social relationship among people. In this paper, we study the problem of social strength modeling (SSM) for the users in a social media community, who are typically associated with diverse form of data. In particular, we take Flickr---the most popular online photo sharing community---as an example, in which users are sharing their experiences through substantial amounts of multimodal contents (e.g., photos, tags, geo-locations, friend lists) and social behaviors (e.g., commenting and joining interest groups). Such heterogeneous …

Context-Based Friend Suggestion In Online Photo-Sharing Community, Ting Yao, Chong-Wah Ngo, Tao Mei

Research Collection School Of Computing and Information Systems

With the popularity of social media, web users tend to spend more time than before for sharing their experience and interest in online photo-sharing sites. The wide variety of sharing behaviors generate different metadata which pose new opportunities for the discovery of communities. We propose a new approach, named context-based friend suggestion, to leverage the diverse form of contextual cues for more effective friend suggestion in the social media community. Different from existing approaches, we consider both visual and geographical cues, and develop two user-based similarity measurements, i.e., visual similarity and geo similarity for characterizing user relationship. The problem of …

Measuring Social Networks For Real-Time Competitive Advantage, Singapore Management University

Perspectives@SMU

Social networks offer up a goldmine of information just waiting to be exploited. For the first time, human relationships, comments and activities are documented quite publicly on platforms like Facebook and Twitter. Save for privacy concerns, never before has it been easier to know what people think, what they like, and to whom they are connected.

Exploring Tweets Normalization And Query Time Sensitivity For Twitter Search, Zhongyu Wei, Wei Gao, Lanjun Zhou, Binyang Li, Kam-Fai Wong

Research Collection School Of Computing and Information Systems

This paper presents our work for the Realtime Adhoc Task of TREC 2011 Microblog Track. Microblog texts like tweets are generally characterized by the inclusion of a large proportion of irregular expressions, such as ill-formed words, which can lead to significant mismatch between query terms and tweets. In addition, Twitter queries are distinguished from Web queries with many unique characteristics, one of which reflects the clearly distinct temporal aspects of Twitter search behavior. In this study, we deal with the first problem by normalizing tweet texts and the second by capturing the temporal characteristics of topic. We divided topics into …

Mining Direct Antagonistic Communities In Explicit Trust Networks, David Lo, Didi Surian, Zhang Kuan, Ee Peng Lim

Research Collection School Of Computing and Information Systems

There has been a recent increase of interest in analyzing trust and friendship networks to gain insights about relationship dynamics among users. Many sites such as Epinions, Facebook, and other social networking sites allow users to declare trusts or friendships between different members of the community. In this work, we are interested in extracting direct antagonistic communities (DACs) within a rich trust network involving trusts and distrusts. Each DAC is formed by two subcommunities with trust relationships among members of each sub-community but distrust relationships across the sub-communities. We develop an efficient algorithm that could analyze large trust networks leveraging …

Virality Modeling And Analysis, Tuan Anh Hoang, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Virality is a virus-like behavior that allows a piece of information to widely and quickly diffuse within the network of adopters through word of mouth. It is about how easy users propagate information to their friends and friends of friends by means of diffusion. While virality of information has several interesting applications, there are much research to be conducted on virality. These areas of research include understanding the mechanism of virality, modeling the virality both qualitatively and quantitatively, and applying virality to applications such as marketing, event detection, and others. In this paper, we survey existing works on quantitative models …

A Survey Of Information Diffusion Models And Relevant Problems, Minh Duc Luu, Tuan Anh Hoang, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

There has been tremendous interest in diffusion of innovations or information in a social system. Nowadays, social networks (offline as well as online) are considered as important medium for diffusion and large amount of research has been conducted to understand the dynamics of diffusion in social networks. In this work, we review some of the models proposed for diffusion in social networks. We also highlight the major features of these models by dividing the surveyed models into two categories: non-network and network diffusion models. The former refers to user communities without any knowledge about the user relationship network and the …

On Modeling Virality Of Twitter Content, Tuan Anh Hoang, Ee Peng Lim, Palakorn Achananuparp, Jing Jiang, Feida Zhu

Twitter is a popular microblogging site where users can easily use mobile phones or desktop machines to generate short messages to be shared with others in realtime. Twitter has seen heavy usage in many recent international events including Japan earthquake, Iran election, etc. In such events, many tweets may become viral for different reasons. In this paper, we study the virality of socio-political tweet content in the Singapore’s 2011 general election (GE2011). We collected tweet data generated by about 20K Singapore users from 1 April 2011 till 12 May 2011, and the follow relationships among them. We introduce several quantitative …

Growing Singapore's Funny Bone: Laughing In The Face Of Dangers, Pitfalls And Politicians, Singapore Management University

Perspectives@SMU

There was once a time in Singapore when the mocking of authority figures would be regarded as a no-go zone. Leaders and politicians were rarely subjects of comedy for such jokes would be considered too distasteful and disrespectful for mass consumption. Acceptable local comedy, as such, was limited to the physical and sometimes lowbrow variety.

Creating Social Contagion Through Viral Product Design: A Randomized Trial Of Peer Influence In Networks, Sinan Aral, Dylan Walker

Business Faculty Articles and Research

We examine how firms can create word-of-mouth peer influence and social contagion by designing viral features into their products and marketing campaigns. To econometrically identify the effectiveness of different viral features in creating social contagion, we designed and conducted a randomized field experiment involving the 1.4 million friends of 9,687 experimental users on Facebook.com. We find that viral features generate econometrically identifiable peer influence and social contagion effects. More surprisingly, we find that passive-broadcast viral features generate a 246% increase in peer influence and social contagion, whereas adding active-personalized viral features generate only an additional 98% increase. Although active-personalized viral …

Community Affair: Social Inclusion And Swapping, Jowanza Joseph

Student Works

Swapping has become primitive economic behavior with the advent of currency. However, with the increase in concern about the environment swapping has emerged in many forums including swap meets, free cycle and online swapping forums. We perform an exploratory investigation of this behavior through an imperial investigation of Twitter. We test the connectedness, and the popularity of people who are involved in swap meets and farmers markets. Finally, we discuss the implications and future directions for swapping.

Media Landscape In Twitter: A World Of New Conventions And Political Diversity, Jisun An, Meeyoung Cha, Krishna Gummadi, Jon Crowcroft

Research Collection School Of Computing and Information Systems

We present a preliminary but groundbreaking study of the media landscape of Twitter. We use public data on whom follows who to uncover common behaviour in media consumption, the relationship between various classes of media, and the diversity of media content which social links may bring. Our analysis shows that there is a non-negligible amount of indirect media exposure, either through friends who follow particular media sources, or via retweeted messages. We show that the indirect media exposure expands the political diversity of news to which users are exposed to a surprising extent, increasing the range by between 60-98%. These …

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.

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 …

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 …
