Assessing The Reliability Of Relevant Tweets And Validation Using Manual And Automatic Approaches For Flood Risk Communication, Xiaohui Liu, Bandana Kar, Francisco Alejandro Montiel Ishino, Chaoyang Zhang, Faustine Williams

Faculty Publications

© 2020 by the authors. While Twitter has been touted as a preeminent source of up-to-date information on hazard events, the reliability of tweets is still a concern. Our previous publication extracted relevant tweets containing information about the 2013 Colorado flood event and its impacts. Using the relevant tweets, this research further examined the reliability (accuracy and trueness) of the tweets by examining the text and image content and comparing them to other publicly available data sources. Both manual identification of text information and automated (Google Cloud Vision, application programming interface (API)) extraction of images were implemented to balance accurate …

Discretionary Dissemination On Twitter, Richard M. Crowley, Wenli Huang, Hai Lu

Research Collection School Of Accountancy

Using an unsupervised machine learning approach to analyze 12.8 million tweets posted by S&P 1500 firms from 2012 to 2016, we find that firms tweet more financial information around significantly negative or positive earnings announcements or accounting filings. Specifically, we observe a symmetric U-shaped relation between the number of financial tweets and the materiality of accounting information events. This relation is consistent with the theoretical prediction in Hummel et al. (2018) which assumes that managers are sensitive to their firm’s fundamental value. We document that this relation also holds for hyperlink usage in tweets about financial information around important events, …

Extending Ethos In Digital Rhetorics, Andrew J. Hillen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation researched the concept of ethos, or appeal to authority or trust, on the social media platform, Twitter. Looking at collections of tweets, I found that the characteristics of the Twitter platform, as well as the general qualities of writing online, pushed users to use short cuts to trust, such as focusing in on specific buzz words, or through referencing well known organizations and individuals. Users also used internet culture as its own source of authority. They demonstrated that they were up to date on the latest trends and memes, and so were trustworthy accounts to follow. Users appealed …

Tweeting During A Crisis: Best Practices For Public Relations (Pr) Professionals For Reputation Management During Racial Bias Cases, Gabrielle Vanadia

Seton Hall University Dissertations and Theses (ETDs)

There are multiple message strategies utilized for public relations (PR) when communicating information on Twitter during a crisis. The purpose of this study was to determine the most effective reputation repair practice(s) used during racially bias related crises surrounding three retail companies. Tweets from the crisis response phase conveying apology, corrective action, denial, evasion of responsibility, and reduce offensiveness were examined in terms of likes, retweets, and replies through a case study and textual analysis approach. Results revealed that the reduce offensiveness strategy yielded the highest overall engagement and produced a best practices guide for future public relations professionals.

@Gretathunberg: Navigating Critique And Identity Within Youth Climate Activism On Twitter, Carina Robin Weadock

Electronic Theses and Dissertations

Youth climate activist Greta Thunberg sat alone on the steps of the Swedish Parliament building in September of 2018, holding a bold black and white sign and demanding action be taken in the face of the climate crisis. Ever since, her activism and Twitter presence have sparked media attention, catalyzed youth activists globally to organize marches and strike from school, and have drawn critique. This thesis employs McKerrow’s (1989) critical rhetoric to uncover dominant discourses within tweets that undermine Thunberg based on identity and to explore the potential that Thunberg’s Twitter presence might or might not hold for future youth …

Exploring Crisis Communication And Information Dissemination On Social Media: Social Network Analysis Of Hurricane Irma Tweets, Xianlin Jin

Communication Graduate Research

This study utilized social network analysis to identify the top 10 Twitter influentials during the Hurricane Irma crisis period and examined the relationship between social media attributes and the bridge influence of controlling information flow. The number of a user’s followers and tweets significantly predicted one’s control of information. Crisis information tended to be shared in scattered subgroups. Social network boundaries impeded information diffusion, and the communication pattern was largely one-way. The findings partially supported the opinion leader argument while indicating that influentials can directly generate information, which is consistent with the social-mediated crisis communication model. Such findings will contribute …

How Misinformation Spreads Through Twitter, Mary Blankenship

Student Research

While living in the age of information, an inherent drawback to such high exposure to content lends itself to the precarious rise of misinformation. Whether it is called “alternative facts,” “fake news,” or just incorrect information, because of its pervasiveness in nearly every political and policy discussion, the spread of misinformation is seen as one of the greatest challenges to overcome in the 21st century. As new technologies emerge, a major piece of both content creation and the perpetuation of misinformation are social media platforms like Twitter, Facebook, and YouTube. As news events emerge, whether be a pandemic, a mass …

Educator Professional Conversations Via Twitter Chat: Speech Acts And Intentions In #Pdbookclub, Suzanne L. Porath

Current Issues in Emerging eLearning

#PDBookChat was an affinity space of educators who read a professional book together and reflected on their learning through blogs, Twitter, and Google+. The book study culminated with an hour-long synchronous Twitter chat. Using Computer-Mediated Discourse Analysis (Herring, 2001) and speech act theory (Searle, 1976) this paper focused on the Twitter chat to examine the discussion among the participants, the specific ways in which they connected their responses to each other and the content of the professional book they read, and provided an analysis of the key themes of the chat. This research provides evidence of how educators use Twitter …

Social Media, Journalism And Crisis: Twitter Representation Of #Syrianrefugees In Western News Media, Ahmad Khaled Alshallal

Dissertations

Generally, there have been conflicts in the world regarding media coverage especially on #SyrianRefugees in Western media. It is undebatable that the Western states have political stability and peace; thus, they remain better hosts for asylum seekers and other refugees who come in search of greener pastures. However, current trends have hindered such countries from being ideal hubs because citizens have basic fears including those related to national security. Refugee situations have attracted lots of controversies over the years to the point that the concern is evident in the media. This dissertation explores the crisis of Syrian refugees and the …

Sentiment Analysis, Quantification, And Shift Detection, Kevin Labille

Graduate Theses and Dissertations

This dissertation focuses on event detection within streams of Tweets based on sentiment quantification. Sentiment quantification extends sentiment analysis, the analysis of the sentiment of individual documents, to analyze the sentiment of an aggregated collection of documents. Although the former has been widely researched, the latter has drawn less attention but offers greater potential to enhance current business intelligence systems. Indeed, knowing the proportion of positive and negative Tweets is much more valuable than knowing which individual Tweets are positive or negative. We also extend our sentiment quantification research to analyze the evolution of sentiment over time to automatically detect …

The Alternative Voice: A Content Analysis Of Twitter News Accounts In Kuwait, Yousef Aldaihani

Dissertations

In response to the Agenda Setting scholars’ calls to locate innovative methods to gauge public salience in the evolving communication environment, this study used retweets, likes, and replies to measure public salience on two types of Kuwaiti Twitter news accounts: traditional newspapers accounts, and alternative news accounts. It also aimed to examine the potential effect of media salience constructs: attention, prominence, and valence on public perceived salience. The study was conducted on a 2203 systematically selected tweets from six news accounts. Results revealed that the agenda of the two types were positively significantly correlated. Social issues and politics were the …

Do Firms Manage Their Csr Reputation? Evidence From Twitter, Richard M. Crowley, Wenli Huang, Hai Lu, Wei Luo

Research Collection School Of Accountancy

Using a machine learning approach to process 11 million tweets posted by S&P 1500 firms from 2011 through 2016, we find that poor CSR performance firms tweet more about CSR activities and use tweets that are shorter, and with more passive voice and extreme tone. Good CSR performance firms tweet less about CSR, yet gain twice more followers per CSR tweet than poor CSR performance firms. Good CSR performance firms also experience a greater decrease in institutional ownership along with higher increases in bid-ask spread and stock return volatility after joining Twitter than do poor CSR performance firms. Our findings …

Collaborative Speculation And Overvaluation: Evidence From Social Media, Adam Barrett Booker

Graduate Theses and Dissertations

I use data from StockTwits and Twitter to provide evidence that investor attention on social media in the period before earnings is related to short-term overvaluation, consistent with bullish investors herding around common information. In the 2 to 60 days after earnings, returns for companies in the highest quintile of pre-earnings announcement investor attention are 4.2 percent lower than those of companies in the lowest quintile. I find evidence that the negative post-earnings drift result found in this study is related to investors waiting until after earnings are announced to enact costly arbitrage strategies. I further examine intra- and inter-network …

We collected 3,163,373 social posts from 53 news organizations across five platforms during an 8month period. We analyzed the differences in news organization platform strategies by focusing on topic variations by organization and the corresponding effect on user engagement at four levels. Findings show that topic distribution varies by platform, although there are some topics that are popular across most platforms. User engagement levels vary both by topics and …

The Affective Politics Of Twitter, Johnathan C. Flowers

Computer Ethics - Philosophical Enquiry (CEPE) Proceedings

Given the increasing encroachment of Twitter into offline experience, it has become necessary to look beyond the formation of identity in online spaces to the ways in which identities surface through the formation of affective communities organized through the use of technocultural assemblages, or the platforms, algorithms, and digital networks through which affect circulates in an online space. This essay focuses on the microblogging website Twitter as one such technocultural assemblage whose hashtag functionality allows for the circulation of affect among bodies which “surface” within the affective communities organized on Twitter through their alignment with and orientation by hashtags which …

Leveraging Natural Language Processing Applications And Microblogging Platform For Increased Transparency In Crisis Areas, Ernesto Carrera-Ruvalcaba, Johnson Ekedum, Austin Hancock, Ben Brock

SMU Data Science Review

Through microblogging applications, such as Twitter, people actively document their lives even in times of natural disasters such as hurricanes and earthquakes. While first responders and crisis-teams are able to help people who call 911, or arrive at a designated shelter, there are vast amounts of information being exchanged online via Twitter that provide real-time, location-based alerts that are going unnoticed. To effectively use this information, the Tweets must be verified for authenticity and categorized to ensure that the proper authorities can be alerted. In this paper, we create a Crisis Message Corpus from geotagged Tweets occurring during 7 hurricanes …

Electoral Competitiveness And Social Media Strategies: Who Goes Negative When And Why?, Connor Brown

Political Science Theses and Capstones

Social media is becoming more integrated into every politician’s career. Previous research suggests that throughout an election a challenger is the one who is more likely to use negative campaigning while running for office. I analyze what strategies are being used by challengers and incumbent candidates while running for office. The data I use is provided by Zachary Auter and Jeffrey Fine (2016). Their data looks at both the 2010 election where we began to see politicians use Facebook ads in their campaigns. I find that a challenger is more likely to adopt negative messages while they are running and …

Tweeting In Public: How Florida's Public Information Officers Use Twitter To Engage The Publics They Serve, Jessica B. Scott

UNF Graduate Theses and Dissertations

This study expands Twitter interactivity research in the area of public relations. A content analysis of tweets from public information Twitter accounts in Florida counties examines the degree to which county public information officers interact with the publics on Twitter. Engagement on Twitter is examined using a coding scheme adapted from previous research (McMillan, 2002; Otterbacher, Shapiro, & Hemphill, 2012; Parmelee & Deeley, 2017), which is a more sophisticated measure of interactivity than merely counting the presence of replies and retweets. Findings indicate that when public information officers engage in mutual discourse, or the exchange of information in two-way communication, …
