A Crowdsourcing Approach To Identify Common Method Bias And Self-Representation, Margeret A. Hall, Simon Caton

Interdisciplinary Informatics Faculty Proceedings & Presentations

Pertinent questions on the measurement of social indicators are: the verification of data gained online (e.g., controlling for self-representation on social networks), and appropriate uses in community management and policy-making. Across platforms like Facebook, LinkedIn, Twitter, and blogging services, users (sub)consciously represent themselves in a way which is appropriate for their intended audience (Qui et al., 2012; Zhao et al., 2008). However, scholars in the social sciences and computer science have not yet adequately addressed controlling for self-representation, or the propensity to display or censor oneself, in their analyses (Zhao et al., 2008; Das and Kramer, 2013). As such researchers …

Interestingness-Driven Diffussion Process Summarization In Dynamic Networks, Qiang Qu, Siyuan Liu, Christian Jensen, Feida Zhu, Christos Faloutsos

Research Collection School Of Computing and Information Systems

The widespread use of social networks enables the rapid diffusion of information, e.g., news, among users in very large communities. It is a substantial challenge to be able to observe and understand such diffusion processes, which may be modeled as networks that are both large and dynamic. A key tool in this regard is data summarization. However, few existing studies aim to summarize graphs/networks for dynamics. Dynamic networks raise new challenges not found in static settings, including time sensitivity and the needs for online interestingness evaluation and summary traceability, which render existing techniques inapplicable. We study the topic of dynamic …

Sharing Political News: The Balancing Act Of Intimacy And Socialization In Selective Exposure, Jisun An, Daniele Quercia, Meeyoung Cha, Krishna Gummadi, Jon Crowcroft

Research Collection School Of Computing and Information Systems

One might think that, compared to traditional media, social media sites allow people to choose more freely what to read and what to share, especially for politically oriented news. However, reading and sharing habits originate from deeply ingrained behaviors that might be hard to change. To test the extent to which this is true, we propose a Political News Sharing (PoNS) model that holistically captures four key aspects of social psychology: gratification, selective exposure, socialization, and trust & intimacy. Using real instances of political news sharing in Twitter, we study the predictive power of these features. As one might expect, …

An Exploratory Study On Software Microblogger Behaviors, Yuan Tian, David Lo

Research Collection School Of Computing and Information Systems

Microblogging services are growing rapidly in the recent years. Twitter, one of the most popular microblogging sites, has gained more than 500 millions users. Thousands of developers are also using Twitter to communicate with one another and microblog about software-related topics such as programming languages, code libraries, etc. Understanding the behaviors of software microbloggers is one of the needed first steps toward building automated tools to encourage software microblogging activities and harness software microblogging to improve various software engineering activities. In this paper, we investigate the behaviors of software microbloggers in terms of their microblogging frequency, generated contents, and interactions …

A Study Of Age Gaps Between Online Friends, Lizi Liao, Jing Jiang, Ee Peng Lim, Heyan Huang

Research Collection School Of Computing and Information Systems

User attribute extraction on social media has gain considerable attention, while existing methods are mostly supervised which suffer great diffi- culty in insufficient gold standard data. In this paper, we validate a strong hypothesis based on homophily and adapt it to ensure the certainty of user attribute we extracted via weakly supervised propagation. Homophily, the theory which states that people who are similar tend to become friends, has been well studied in the setting of online social networks. When we focus on age attribute, based on this theory, online friends tend to have similar age. In this work, we take …

Clear: A Real-Time Online Observatory For Bursty And Viral Events, Runquan Xie, Feida Zhu, Hui Ma, Wei Xie, Chen Lin

Research Collection School Of Computing and Information Systems

We describe our demonstration of CLEar (Clairaudient Ear), a real-time online platform for detecting, monitoring, summarizing, contextualizing and visualizing bursty and viral events, those triggering a sudden surge of public interest and going viral on micro-blogging platforms. This task is challenging for existing methods as they either use complicated topic models to analyze topics in a off-line manner or define temporal structure of fixed granularity on the data stream for online topic learning, leaving them hardly scalable for real-time stream like that of Twitter. In this demonstration of CLEar, we present a three-stage system: First, we show …

It's Complicated: The Role Of Facebook In Romantic Relationships Concerning Relational Certainty, Attachment, And Self-Esteem, Jenna Rae Tucker

Dissertations and Theses

Facebook is among the top used websites in the world, and research has shown that Facebook use is related to individual personality characteristics such as well-being and self-esteem. This study builds on previous research, expanding to investigate attachment-related anxiety and avoidance and relational certainty. The current study examined relationships between Facebook use (both general and for surveillance) and relational certainty, attachment-related anxiety and avoidance, and self-esteem in undergraduate students (N = 261). Online methods were used for data collection, and individuals with their relationship displayed on Facebook reported more relational certainty; however, the more time they spent on the site, …

Opinion Mining Of Sociopolitical Comments From Social Media, Swapna Gottipati

Dissertations and Theses Collection (Open Access)

Opinions are central to almost all human activities by influencing greatly the decision making process. In this thesis, we present the problems of mining issues, extracting entities and suggestive opinions towards the entities, detecting thoughtful comments, and extracting stances and ideological expressions from online comments in the sociopolitical domain. This study is essential for opinion mining applications that are beneficial for policy makers, government sectors and social organizations. Much work has been done to try to uncover consumer sentiments from online comments to help businesses improve their products and services. However, sociopolitical opinion mining poses new challenges due to complex …

Toward A Uses And Gratification's Model Of Twitter, Philip Ryan Johnson

Theses - ALL

This study proposed a uses and gratifications model of Twitter, an internet medium and micro-blog--a platform with both mass and interpersonal communication features for sending short messages to others. A survey was conducted among 242 Twitter users to test the model, including a standard investigation of gratifications sought and gratifications obtained of Twitter usage. In addition, expectations and availability of usage behaviors from McLeod and Becker's (1981) uses and gratifications model were examined. In the model, expectations were conceptualized as user expectations of satisfaction and operationalized as the difference between users' gratifications sought and gratifications actually obtained. Usage behavior availability …

On Macro And Micro Exploration Of Hashtag Diffusion In Twitter, Yazhe Wang, Baihua Zheng

Research Collection School Of Computing and Information Systems

This exploratory work studies hashtag diffusion in Twitter. The analysis is conducted from two aspects. From the macro perspective, we study general properties of hashtag diffusion, and classify hashtags into three main classes based on their temporal dynamics referred as 'single spike', 'multi-spikes', and 'fluctuation', and find that each of these classes has some unique characteristics. From the micro perspective, we investigate individual diffusion.We adopt Edelman's 'topology of influence' theory to identify four type of users with different influence levels in diffusion based on their dynamic retweet behaviors. The results of our study are useful for gaining more insights of …

Generating Supplementary Travel Guides From Social Media, Liu Yang, Jing Jiang, Lifu Huang, Minghui Qiu, Lizi Liao

Research Collection School Of Computing and Information Systems

In this paper we study how to summarize travel-related information in forum threads to generate supplementary travel guides. Such summaries presumably can provide additional and more up-to-date information to tourists. Existing multi-document summarization methods have limitations for this task because (1) they do not generate structured summaries but travel guides usually follow a certain template, and (2) they do not put emphasis on named entities but travel guides often recommend points of interest to travelers. To overcome these limitations, we propose to use a latent variable model to align forum threads with the section structure of well-written travel guides. The …

Student-Directed Blended Learning With Facebook Groups And Streaming Media: Media In Asia At Furman University, Tami Blumenfield

Asian Studies Publications

Furman University prizes itself on being an engaged learning, liberal arts institution with extensive faculty-student interaction. 96% of students live on campus, leading some to question whether reducing face-to-face instructional time makes any sense pedagogically. Coming from a different institution that encouraged faculty to create hybrid courses, and seeing the creativity and freedom that offered, I wanted to experiment with the format in this new institutional environment. Would it still be effective? What adaptations would be necessary, and how would students react to this different course format?

In Fall 2013, I taught a carefully designed blended learning course that met …

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 …

Influences Of Influential Users: An Empirical Study Of Music Social Network, Jing Ren, Zhiyong Cheng, Jialie Shen, Feida Zhu

Research Collection School Of Computing and Information Systems

Influential user can play a crucial role in online social networks. This paper documents an empirical study aiming at exploring the effects of influential users in the context of music social network. To achieve this goal, music diffusion graph is developed to model how information propagates over network. We also propose a heuristic method to measure users' influences. Using the real data from Last. fm, our empirical test demonstrates key effects of influential users and reveals limitations of existing influence identification/characterization schemes.

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 …

Predicting The Popularity Of Web 2.0 Items Based On User Comments, Xiangnan He, Ming Gao, Min-Yen Kan, Yiqun Liu, Kazunari Sugiyama

Research Collection School Of Computing and Information Systems

In the current Web 2.0 era, the popularity of Web resources fluctuates ephemerally, based on trends and social interest. As a result, content-based relevance signals are insufficient to meet users' constantly evolving information needs in searching for Web 2.0 items. Incorporating future popularity into ranking is one way to counter this. However, predicting popularity as a third party (as in the case of general search engines) is difficult in practice, due to their limited access to item view histories. To enable popularity prediction externally without excessive crawling, we propose an alternative solution by leveraging user comments, which are more accessible …

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 …

Refusing A Spoiled Identity: How The Swinger Community Represents On The Web, Barbara Kreston

English Theses & Dissertations

This dissertation examines whether and how Websites provide a way for the unique community of swingers, also called Lifestylers, to represent a new (and revise an old) deviant identity without risk to their social and employment standing. Unlike many marginalized social groups who publically rally, swingers have had to take advantage of virtual space to safely appeal to their audiences. The time period studied includes the history of the swingers "spoiled" identity via academy articles, newspaper headlines, and moral turpitude clauses from the 1950s to the current use of the Web to showcase swingers and their clubs. The study used …

"Warning: This Is A Must Read": Participation And Disruption In Social Artifacts And Spaces, Angela M. Harrison Eng

English Theses & Dissertations

As I show in three separate case studies, content, technology, and participant relationships are key components in the design of social artifacts and spaces. One study highlights the invention and evolution of content across multiple spaces. The second shows content used as leverage for authority. The last case study examines the relationship between content and technological interfaces and how disruption may not always be successful.

All of these components make up what I refer to as disruption. Disruption describes participant acts that are executed to change existing power-based structures of information sharing. Using the insights gained from this research, I …

Attitudes Toward Using Social Networking Sites In Educational Settings With Underperforming Latino Youth: A Mixed Methods Study, Keith Howard, Margaret Sauceda Curwen, Nicol R. Howard, Anaida Colon-Muñiz

Education Faculty Articles and Research

The researchers examined the online social networking attitudes of underperforming Latino high school students in an alternative education program that uses technology as the prime venue for learning. A sequential explanatory mixed methods study was used to cross-check multiple sources of data explaining students’ levels of comfort with utilizing a social networking site platform as a supplemental communication tool in connection with their schoolwork. Students were found to be significantly less comfortable using social networking sites than other online communication tools in connection with their schoolwork, and females were significantly more uncomfortable than males using such sites in school.

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 …

Reconsidering Childfreedom: A Feminist Exploration Of Discursive Identity Construction In Childfree Livejournal Communities, Julia Moore

Department of Communication Studies: Faculty Publications

This article employs participant definitional analysis, sensitized with feminist poststructuralism and critical ethnography, to understand three identity construction processes that members of childfree LiveJournal communities participate in: (a) naming childfreedom, (b) negotiating childfreedom, and (c) enacting childfreedom. I argue that childfree identities are contested and sometimes activist. Ultimately, I call for scholars to reconsider the definition of childfree to account for the complex and nuanced identities constructed by individuals who identify as such.
