Mathematical Modeling Of Trending Topics On Twitter, Jonathan S. Skaza

Honors Projects in Mathematics

Created in 2006, Twitter is an online social networking service in which users share and read 140-character messages called Tweets. The site has approximately 288 million monthly active users who produce about 500 million Tweets per day. This study applies dynamical and statistical modeling strategies to quantify the spread of information on Twitter. Parameter estimates for the rates of infection and recovery are obtained using Bayesian Markov Chain Monte Carlo (MCMC) methods. The methodological strategy employed is an extension of techniques traditionally used in an epidemiological and biomedical context (particularly in the spread of infectious disease). This study, which addresses …

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

Social networking sites often are used to maintain close social ties, but increasingly they are used for information and news dissemination, specifically about major events and crises. In 2012, a historic drought struck the Midwest, destroying or damaging portions of major field crops in major agricultural production states. By the end of August 2012, 90% of Nebraska was declared in extreme or exceptional drought, leading to bans on irrigation, damaged crops, and record-low yields as well as damaging the state’s leading economic sector. This case study used social media monitoring and analysis to explore online Twitter conversations related to this …

Knowledge Enabled Approach To Predict The Location Of Twitter Users, Revathy Krishnamurthy, Pavan Kapanipathi, Amit P. Sheth, Krishnaprasad Thirunarayan

Kno.e.sis Publications

Knowledge bases have been used to improve performance in applications ranging from web search and event detection to entity recognition and disambiguation. More recently, knowledge bases have been used to analyze social data. A key challenge in social data analysis has been the identification of the geographic location of online users in a social network such as Twitter. Existing approaches to predict the location of users, based on their tweets, rely solely on social media features or probabilistic language models. These approaches are supervised and require large training dataset of geo-tagged tweets to build their models. As most Twitter users …

Who’S Following Twitter? Coverage Of The Microblogging Phenomenon By U.S. Cable News Networks, Deborah S. Chung, Mina Tsay-Vogel, Yung Soo Kim

Journalism and Media Faculty Publications

Through data captured in a digital content analysis (DCA) lab, we examine coverage of Twitter across three 24-hour U.S. cable news channels: CNN, Fox News Channel, and MSNBC. This investigation tracked Twitter coverage from its initial stage, followed by its rise to a massively used tool and its subsequent diffusion into society, evident through its plateauing coverage. News stories covering Twitter, as it penetrated into society, were more likely to use benefit/gain frames when discussing the technology, highlighting its positive social, communicative, political, and participatory impact. Benefit frames were also likely to associate Twitter with journalism. Patterns …

Twitter Use And Its Effects On Student Perception Of Instructor Credibility, Jocelyn M. Degroot, Valerie J. Young, Sarah H. Vanslette

Applied Communication Studies Faculty Research, Scholarship, and Creative Activity

This study investigates college student perceptions of instructor credibility based on the content of an instructor’s Twitterfeed and student beliefs about Twitter as a communication tool. Quantitative and qualitative methods were utilized to explore the effects of three manipulated Twitter feeds (e.g., tweeting social topics, professional topics, or a blend) on student perceptions of instructor credibility and examine how students perceive Twitter as a teaching tool. Quantitative results suggest that the profile with professional content was most credible. Credibility ratings were also associated with other Twitter use variables, including positive student attitudes about instructors who use Twitter and Tweet frequency. …

Weathering The Storm Surge Of Social Media, Melody Bowdon

UCF Forum

I’ve lived in Central Florida for more than 15 years, and in that time I’ve seen quite a few serious weather events affect our community. Though the hurricane season starts in the summer, around here we tend to become especially aware of the storm possibilities in the early fall, when more tropical activity spins up in the ocean and when annual milestones that have been marred by big storms in previous years come up on our calendars.

"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 …

Active Learning With Efficient Feature Weighting Methods For Improving Data Quality And Classification Accuracy, Justin Martineau, Lu Chen, Doreen Cheng, Amit P. Sheth

Kno.e.sis Publications

Many machine learning datasets are noisy with a substantial number of mislabeled instances. This noise yields sub-optimal classification performance. In this paper we study a large, low quality annotated dataset, created quickly and cheaply using Amazon Mechanical Turk to crowdsource annotations. We describe computationally cheap feature weighting techniques and a novel non-linear distribution spreading algorithm that can be used to iteratively and interactively correcting mislabeled instances to significantly improve annotation quality at low cost. Eight different emotion extraction experiments on Twitter data demonstrate that our approach is just as effective as more computationally expensive techniques. Our techniques save a considerable …

The project explored and analyzed the use of the social media tool Twitter in the immediate aftermath of a major event. Tweets and re-tweets from the first hour following the Boston Marathon Bombings on April 15, 2013 were collected and analyzed. The project used the application SIFTER from the company Textifer to identify the related tweets by inputting sixteen previously documented keywords related to the Boston Marathon Bombing. The tweets were then divided into several categories and subcategories to be analyzed. The company Twitter Counter was used to obtain accurate information, such as followers on, for various individual Twitter accounts. …

Using Statistical Methods To Determine Geolocation Via Twitter, Christopher M. Wright

Masters Theses & Specialist Projects

With the ever expanding usage of social media websites such as Twitter, it is possible to use statistical inquires to form a geographic location of a person using solely the content of their tweets. According to a study done in 2010, Zhiyuan Cheng, was able to detect a location of a Twitter user within 100 miles of their actual location 51% of the time. While this may seem like an already significant find, this study was done while Twitter was still finding its ground to stand on. In 2010, Twitter had 75 million unique users registered, as of March 2013, …

Gatekeeping The Social Games In A Post-Broadcasting World: A Qualitative Content Analysis Of Nbc And User-Generated Olympic Twitter Coverage During The 2012 London Games, Daniel Anthony Sipocz

Dissertations

This study examined the Twitter use of both traditional gatekeepers, such as NBC, and audience members during the 2012 London Summer Olympics. The exploratory study examined NBC and audience members as gatekeepers with a particular interest in the audience’s role as a gatekeeper through social media use. NBC used Twitter, a social media platform, in ways that supported traditional gatekeeping models. The network aimed to drive audiences back to the traditional television broadcast while providing the audience with the illusion of having an influence on Olympic coverage. Most significantly, this study argues that the audience became a gatekeeper of Olympic …

Hierarchical Interest Graph From Tweets, Pavan Kapanipathi, Prateek Jain, Chitra Venkataramani, Amit P. Sheth

Kno.e.sis Publications

Industry and researchers have identified numerous ways to monetize microblogs for personalization and recommendation. A common challenge across these different works is the identification of user interests. Although techniques have been developed to address this challenge, a flexible approach that spans multiple levels of granularity in user interests has not been forthcoming. In this work, we focus on exploiting hierarchical semantics of concepts to infer richer user interests expressed as a Hierarchical Interest Graph. To create such graphs, we utilize users' tweets to first ground potential user interests to structured background knowledge such as Wikipedia Category Graph. We then adapt …

Cursing In English On Twitter, Wenbo Wang, Lu Chen, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

Cursing is not uncommon during conversations in the physical world: 0.5% to 0.7% of all the words we speak are curse words, given that 1% of all the words are first-person plural pronouns (e.g., we, us, our). On social media, people can instantly chat with friends without face-to-face interaction, usually in a more public fashion and broadly disseminated through highly connected social network. Will these distinctive features of social media lead to a change in people's cursing behavior? In this paper, we examine the characteristics of cursing activity on a popular social media platform - Twitter, involving the analysis of …

Location Prediction Of Twitter Users Using Wikipedia, Revathy Krishnamurthy, Pavan Kapanipathi, Amit P. Sheth, Krishnaprasad Thirunarayan

Kno.e.sis Publications

The mining of user generated content in social media has proven very effective in domains ranging from personalization and recommendation systems to crisis management. The knowledge of online users locations makes their tweets more informative and adds another dimension to their analysis. Existing approaches to predict the location of Twitter users are purely data-driven and require large training data sets of geo-tagged tweets. The collection and modelling process of tweets can be time intensive. To overcome this drawback, we propose a novel knowledge based approach that does not require any training data. Our approach uses information in Wikipedia, about cities …

Predicting Events Surrounding The Egyptian Revolution Of 2011 Using Learning Algorithms On Micro Blog Data, Benedikt Boecking, Margeret A. Hall, Jeff Schneider

Interdisciplinary Informatics Faculty Proceedings & Presentations

We aim to predict activities of political nature in Egypt which influence or reflect societal-scale behavior and beliefs by using learning algorithms on Twitter data. We focus on capturing domestic events in Egypt from November 2009 to November 2013. To this extent we study underlying communication patterns by evaluating content-based and meta-data information in classification tasks without targeting specific keywords or users. Classification is done using Support Vector Machines (SVM) and Support Distribution Machines (SDM). Latent Dirichlet Allocation (LDA) is used to create content-based input patterns for the classifiers while bags of Twitter meta-information are used with the SDM to …

A Christian Mega Church Strives For Relevance: Examining Social Media And Religiosity, Kenthea Albert-Leigh Joan Fogenay

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study is to evaluate the relationship between Facebook and Twitter uses and gratifications and religiosity. Non-denominational Christian mega churches focus their outreach programs on a "come-as-you-are" attitude with the hopes of making people feel comfortable. The interactive technology in our daily lives also infiltrates our experience at church. The congregation now has the ability to worship through technologies endorsed by leadership (Watson & Scalen, 2008; Bogomilova, 2004; Thomas, 2009). In order for churches to engage in effective communication, they must understand how people use social networking. Through survey methodology, the researcher takes an account of how …

Networking Young Citizens : Learning To Be Citizens In And With The Social Web, Suzanne Mellor, Terri Seddon

Civics and Citizenship Assessment

Many claims are made, both in the popular press and the professional education literature, about the significance of the social web in enabling civic participation. However empirical evidence supporting these claims is sparse and contested rather than strongly-indicative. The Monash University pilot research project, Networking Young Citizens, relates to the discussion about the ways in which the social web might support the civic participation, especially of young people, by examining the ways in which Web 2.0 was integrated into teaching and learning in the school, and any other processes of civic socialisation that were consciously adopted in three schools.

The study aims to help editors understand which approaches to social media attract audiences and increase reader or audience interaction.

Hashtag Politics: The Polyphonic Revolution Of #Twitter, Bud Davis

Pepperdine Journal of Communication Research

Social media has revolutionized how citizens communicate and interact with each other. President Barack Obama’s 2008 presidential campaign notably demonstrated just how impactful online interconnectivity could be in reaching out to key demographics. More specifically, Twitter has become increasingly popular in achieving communication with constituents while enabling voters to become citizen journalists and active participants in the political process. This paper seeks to trace the evolution of Twitter as a political resource and determine what influence it has in enhancing and inhibiting political communication. By drawing on Kristeva’s concept of intertextuality, I argue that Twitter’s unique functionality contains the potential …

A Quantitative Survey: Are Twitter Advertisements Effective For College Students?, Christia J. Brockman

Communication Studies

Social Media websites are rapidly being overrun by advertisements, but is this blitz of advertising destroying the social media experience? Twitter, one of today’s most popular social media sites, increased its revenues from $45,000,000 in 2010 to $259 million in 2013. This exponential growth is surprising given the large portion of Twitter users who are between the ages of 18 to 25 with lower annual incomes. In analyzing whether advertising on Twitter is effective on college students, statistical results from a survey conducted among college students at California Polytechnic State University, San Luis Obispo, reveal that Tweeters in this sample …

The Next to Normal Twitter account gathered over one million followers throughout a six-week campaign in which the Situation Interactive team joined forces with the book writer and lyricist of Next to Normal to recreate the plot in one hundred and forty-character snippets. By analyzing the data collected the researcher cultivates a collection of best practices for running a successful Twitter marketing campaign for a live experience.

Social Media And The Transformation Of The Humanitarian Narrative: A Comparative Analysis Of Humanitarian Discourse In Libya 2011 And Bosnia 1994, Ellen Noble

Political Science Honors Projects

Within humanitarian discourse, there is a prevailing narrative: the powerful liberal heroes are saving the helpless, weak victims. However, the beginning of the 21^st century marks the expansion of the digital revolution throughout lesser-developed states. Growing access to the Internet has enabled aid recipients to communicate with the outside world, giving them an unprecedented opportunity to reshape discourses surrounding humanitarianism. Through a comparative discourse analysis of Libyan Tweets, 1994 newspaper reports on Bosnia, and 2011 newspaper reports on Libya, this paper analyzes whether aid recipient discourse can resist the dominant humanitarian narrative and if that resistance can influence dominant …

Building Collaboration Within The Quarter Horse Community: The Obstacles And Hurdles, Allison Grayson

Journalism

The following study investigates how to increase collaboration within the Quarter Horse community through Twitter. Twitter is increasingly one of the top social media tools for many organizations, including organizations within the Quarter Horse community. Twitter is an important tool in creating a dialogue between community members, and the organizations to which they are members. Research shows, “Users believe that using Twitter can improve their performance or their ability to achieve specific goals and, thus, they are more extrinsically motivated to continue to use it” (Agrifoglio, Black, Ferrara & Metallo, 2012, p. 38). That being said, it is important that …

City Magazines And Social Media: Moving Beyond The Monthly, Susan Currie Sivek
