Analysis Of Malicious Behavior On Social Media Platforms Using Agent-Based Modeling, Agnieszka Anna Onuchowska

USF Tampa Graduate Theses and Dissertations

The following dissertation focuses on the problem of malicious accounts actions on social media. The dissertation proposes an artifact in a form of an agent-based model of Twitter network. The model is then deployed to investigate a policy intervention that aims at controlling malicious behavior on social media outlets. The main research question is: How can we best intervene in social networks to minimize the effects of malicious actors? The dissertation consists of four studies that are organized as follows. First study is designed as an exploratory investigation that deploys descriptive analysis and unsupervised methods to analyze the types of …


Characterizing Health Behavior Information: Developing A Surveillance Text Mining Framework Using Twitter For Diet, Diabetes, Exercise, And Obesity, George Shaw Jr. Jan 2018

Characterizing Health Behavior Information: Developing A Surveillance Text Mining Framework Using Twitter For Diet, Diabetes, Exercise, And Obesity, George Shaw Jr.

Theses and Dissertations

Previous studies have documented the relationship that exists among diabetes, diet, exercise, and obesity. Obesity increases people’s risk of developing heart disease and type 2 diabetes. Exercise and proper dieting are modifiable lifestyle behaviors that can help with reducing people’s overall weight and risk to various chronic conditions like diabetes. A national survey conducted by the Centers for Diseases Control and Prevention (CDC) is the annual Behavioral Risk Factor Surveillance Survey (BRFSS). Twitter provides researchers with a new opportunity and alternative data source to collect information regarding health behaviors using real-time data. Previous studies have demonstrated Twitter’s ability to monitor …


Effects Of Gatekeeping On The Diffusion Of Information, Rebecca Anderson Aug 2017

Effects Of Gatekeeping On The Diffusion Of Information, Rebecca Anderson

Doctoral Dissertations

This study proposes a theoretical model of information diffusion using the conceptual framework of Gatekeeping Theory (Shoemaker & Vos, 2009). Diffusion is a process by which elements are distributed through a social system (Rogers, 2003; Kadushin, 2012). This model builds on previous diffusion research and incorporates constructs of authority and vivid information, novel to the domain. To test the fit of the model, Twitter data derived using data mining techniques are utilized. Specifically, messages posted to Twitter relating to the 2013 Consumer Electronics (CES) conference are mined. Essentially, this study focuses on the diffusion of technology information through a popular …


Informational Power On Twitter: A Mixed-Methods Exploration Of User Knowledge And Technological Discourse About Information Flows, Nicholas John Proferes May 2015

Informational Power On Twitter: A Mixed-Methods Exploration Of User Knowledge And Technological Discourse About Information Flows, Nicholas John Proferes

Theses and Dissertations

Following a number of recent examples where social media users have been confronted by information flows that did not match their understandings of the platforms, there is a pressing need to examine public knowledge of information flows on these systems, to map how this knowledge lines up against the extant flows of these systems, and to explore the factors that contribute to the construction of knowledge about these systems. There is an immediacy to this issue because as social media sites become further entrenched as dominant vehicles for communication, knowledge about these technologies will play an ever increasing role in …


Understanding Wisconsin Legislators' Use Of Social Media, Christian T. Moran Dec 2013

Understanding Wisconsin Legislators' Use Of Social Media, Christian T. Moran

Theses and Dissertations

This thesis used quantitative and qualitative methods to examine the use of social media by legislative offices of the Wisconsin State Assembly. A survey of legislators and their staff documented the extent to which each office uses Facebook or Twitter. In addition, multivariate analysis of the survey data provided an understanding of which kinds of legislators are more likely to use Facebook or Twitter. There were three important findings. First, most Wisconsin legislators whose offices use Facebook or Twitter do not seem to be doing so to reach the news media. Second, overall, the characteristics of a Wisconsin legislator are …
