Reviving Dormant Ties In An Online Social Network Experiment, Ee Peng Lim, Denzil Correa, David Lo, Michael Finegold, Feida Zhu

Research Collection School Of Computing and Information Systems

Social network users connect and interact with one another to fulfil different kinds of social and information needs. When interaction ceases between two users, we say that their tie becomes dormant. While there are different underlying reasons of dormant ties, it is important to find means to revive such ties so as to maintain vibrancy in the relationships. In this work, we thus focus on designing an online experiment to evaluate the effectiveness of personalized social messages to revive dormant ties. The experiment carefully selects users with dormant ties so that no user gets mixed treatments and be affected by …

The Residual Resistance Of The Individual Within The Rhizomatic Hegemony Of The Internet, Emma Katherine Wolfe

English Theses & Dissertations

Networked cyborgs that exist within the non-hierarchical rhizomatic network of the Internet risk losing the concept of their individuality as our identity becomes less important than the group. However, if the rhizomatic network is thought of as a hegemony that exists on the Internet, we can resist this through the residual notion of individual identity. Since cyborgs must perform in order to exist on the rhizomatic network, they can become aware of and perform their individuality through awareness of the computer medium. There are three methods for networked cyborgs to assert their individuality discussed in this thesis.

The first is …

Engaging And Expanding Communities: Widening The Circle Of Stakeholders, Lisa Deangelis, Maureen A. Scully, Andrea Wight

Emerging Leaders Program Team Projects

The 32 fellows in the 2013 Emerging Leaders Program (ELP) worked with community partners to investigate the theme, “Engaging and Expanding Communities".

They worked with six community partners, and identified ways to help them expand beyond their core stakeholders to a wider circle of stakeholders and broader potential impact. The fellows gave their time and professional skills to understand how to reach new business partners, new participants, new advisors, and new donors. They conducted surveys, interviews, and focus groups; explored social media options; examined best practices; and considered ways to tell powerful stories about the vitally important work of the …

Anomaly Detection On Social Data, Hanbo Dai

Dissertations and Theses Collection (Open Access)

The advent of online social media including Facebook, Twitter, Flickr and Youtube has drawn massive attention in recent years. These online platforms generate massive data capturing the behavior of multiple types of human actors as they interact with one another and with resources such as pictures, books and videos. Unfortunately, the openness of these platforms often leaves them highly susceptible to abuse by suspicious entities such as spammers. It therefore becomes increasingly important to automatically identify these suspicious entities and eliminate their threats. We call these suspicious entities anomalies in social data, as they often hold different agenda comparing to …

From Scrapbook To Facebook: A History Of Personal Media Assemblage And Archives, Katie Day Good

University Faculty Publications and Creative Works

This study surveys recent research on print-era scrapbooks and contemporary social media to highlight commonalities between the two formats, both in terms of the practices they have historically promoted for users, and the methodological challenges they produce for researchers. It argues that scrapbooks and social media can be conceptualized as sites of personal media assemblage and personal media archives, a designation that highlights the simultaneously social and archival dimensions of each form. After discussing these formal similarities, the author identifies three shared functions: (1) documenting friendship, (2) navigating new media abundance, and (3) communicating taste and building cultural capital. By …

Real Time Event Detection In Twitter, Xun Wang, Feida Zhu, Jing Jiang, Sujian Li

Research Collection School Of Computing and Information Systems

Event detection has been an important task for a long time. When it comes to Twitter, new problems are presented. Twitter data is a huge temporal data flow with much noise and various kinds of topics. Traditional sophisticated methods with a high computational complexity aren’t designed to handle such data flow efficiently. In this paper, we propose a mixture Gaussian model for bursty word extraction in Twitter and then employ a novel time-dependent HDP model for new topic detection. Our model can grasp new events, the location and the time an event becomes bursty promptly and accurately. Experiments show the …

A Latent Variable Model For Viewpoint Discovery From Threaded Forum Posts, Minghui Qiu, Jing Jiang

Research Collection School Of Computing and Information Systems

Threaded discussion forums provide an important social media platform. Its rich user generated content has served as an important source of public feedback. To automatically discover the viewpoints or stances on hot issues from forum threads is an important and useful task. In this paper, we propose a novel latent variable model for viewpoint discovery from threaded forum posts. Our model is a principled generative latent variable model which captures three important factors: viewpoint specific topic preference, user identity and user interactions. Evaluation results show that our model clearly outperforms a number of baseline models in terms of both clustering …

Activism, Deliberation, And Networked Public Screens: Rhetorical Scenes From The Occupy Moment In Lincoln, Nebraska (Part 1 & 2), Joshua P. Ewalt, Jessy J. Ohl, Damien S. Pfister

Department of Communication Studies: Faculty Publications

Part 1 of this manuscript is a dramatization of five rhetorical scenes that take the Occupy phenomenon as a moment to explore features of contemporary social protest and change. Drawing on rhetorical field notes collected over the first two weeks of Occupy Lincoln in Nebraska, we identify how historical tensions between activism and deliberation were both complicated and reasserted as the Occupy moment became a movement. The rhetorical scenes partially replicate actual conversations, though they are remediated through three composite figures: Anda, a longtime social activist; John, an advocate of democratic deliberation; and Dajuan, an undergraduate organizer of the local …

Content Analysis: U.S. Newspaper And Social Media Portrayal Of President Obama In Association With The Killing Of Osama Bin Laden During The 2012 Presidential Election Year, Whitney Y. Thomas

The intent of this thesis aims to determine the tone of President Obama in U.S. newspapers and social media in association with the capturing and killing of terrorist Osama bin Laden.

This thesis examines a variety of U.S. newspapers by region and social media. Newspaper articles related to the topic were retrieved from six regional …

Your Love Is Public Now: Questioning The Use Of Personal Information In Authentication, Payas Gupta, Swapna Gottipati, Jing Jiang, Debin Gao

Research Collection School Of Computing and Information Systems

Most social networking platforms protect user's private information by limiting access to it to a small group of members, typically friends of the user, while allowing (virtually) everyone's access to the user's public data. In this paper, we exploit public data available on Facebook to infer users' undisclosed interests on their profile pages. In particular, we infer their undisclosed interests from the public data fetched using Graph APIs provided by Facebook. We demonstrate that simply liking a Facebook page does not corroborate that the user is interested in the page. Instead, we perform sentiment-oriented mining on various attributes of a …

The Genre Of The Meme, Thomas Monson

Colloquy Undergraduate Research Journal

The development and proliferation of the Internet has led to numerous discoveries in the study of media and communication. Such a recent development in online communication is the rise of the online meme. The traditional meaning of meme has been transformed and has developed a new meaning within the sphere of online communication. The meme as defined by its new meaning has recurred in myriads, which have provided enough reason and data to develop a rhetorical genre for the subject. The first half of this study—the background—will begin with an orientation to the meme, an explanation of generic criticism, and …

Personalized News Recommender Using Twitter, Satya Srinivasa Nirmal Jonnalagedda

Graduate Theses and Dissertations

Online news reading has become a widely popular way to read news articles from news sources around the globe. With the enormous amount of news articles available, users are easily swamped by information of little interest to them. News recommender systems are one approach to help users find interesting articles to read. News recommender systems present the articles to individual users based on their interests rather than presenting articles in order of their occurrence. In this thesis, we present our research on developing personalized news recommendation system with the help of a popular micro-blogging service "Twitter". The news articles are …

"Why Can't We Be Friends?:" Does The Quality Of Romantic Relationships Influence Facebook Friendships With Former Romantic Partners, Dylan Medeiros

Graduate Theses and Dissertations

This research attempted to identify relational characteristics of unmarried, romantic partners that ultimately distinguish between former partners who remained Facebook friends versus those who did not. Survey results (N=323) revealed no significant differences between former partners who remained Facebook friends versus those who did not remain Facebook friends based on quantity of relational investments, preference for de-escalatory disengagement strategy, and relational satisfaction.

Unified Entity Search In Social Media Community, Ting Yao, Yuan Liu, Chong-Wah Ngo, Tao Mei

Research Collection School Of Computing and Information Systems

The search for entities is the most common search behavior on the Web, especially in social media communities where entities (such as images, videos, people, locations, and tags) are highly heterogeneous and correlated. While previous research usually deals with these social media entities separately, we are investigating in this paper a unified, multilevel, and correlative entity graph to represent the unstructured social media data, through which various applications (e.g., friend suggestion, personalized image search, image tagging, etc.) can be realized more effectively in one single framework. We regard the social media objects equally as “entities” and all of these applications …

Fragmented Social Media: A Look Into Selective Exposure To Political News, Jisun An, Daniele Quercia, Jon Crowcroft

Research Collection School Of Computing and Information Systems

The hypothesis of selective exposure assumes that people crave like-minded information and eschew information that conflicts with their beliefs, and that has negative consequences on political life. Yet, despite decades of research, this hypothesis remains theoretically promising but empirically difficult to test. We look into news articles shared on Facebook and examine whether selective exposure exists or not in social media. We find a concrete evidence for a tendency that users predominantly share like-minded news articles and avoid conflicting ones, and partisans are more likely to do that. Building tools to counter partisanship on social media would require the ability …

Retweeting: An Act Of Viral Users, Susceptible Users, Or Viral Topics?, Tuan-Anh Hoang, Ee Peng Lim

Research Collection School Of Computing and Information Systems

When a user retweets, there are three behavioral factors that cause the actions. They are the topic virality, user virality and user susceptibility. Topic virality captures the degree to which a topic attracts retweets by users. For each topic, user virality and susceptibility refer to the likelihood that a user attracts retweets and performs retweeting respectively. To model a set of observed retweet data as a result of these three topic specific factors, we first represent the retweets as a three-dimensional tensor of the tweet authors, their followers, and the tweets themselves. We then propose the V 2S model, a …
