Early Detection Of Fake News On Social Media, Yang Liu

Dissertations

The ever-increasing popularity and convenience of social media enable the rapid widespread of fake news, which can cause a series of negative impacts both on individuals and society. Early detection of fake news is essential to minimize its social harm. Existing machine learning approaches are incapable of detecting a fake news story soon after it starts to spread, because they require certain amounts of data to reach decent effectiveness which take time to accumulate. To solve this problem, this research first analyzes and finds that, on social media, the user characteristics of fake news spreaders distribute significantly differently from those …

A Pedagogy Of Techno-Social Relationality: Ethics And Digital Multimodality In The Composition Classroom, Kristin M. Ravel

Theses and Dissertations

I bring together the relational ethics of feminist critical theory with approaches of multimodal rhetoric to examine the ethical implications of composing on social media platforms. Most social media platforms are designed to value consumerism, efficiency, quantity of web traffic, and constant synchronous response over concerns of responsible and critical communication. I propose a rhetorical approach of techno-social relationality (TSR) as an intervention against such corporate-minded design. Through this approach, I argue that civil engagement is not limited to people’s social responsibilities but rather is entwined in complex, material-technical contexts. By considering the responsibility of our machines as much as …

Evaluating Vulnerability To Fake News In Social Networks: A Community Health Assessment Model, Bhavtosh Rath, Wei Gao, Jaideep Srivastava

Research Collection School Of Computing and Information Systems

Understanding the spread of false information in social networks has gained a lot of recent attention. In this paper, we explore the role community structures play in determining how people get exposed to fake news. Inspired by approaches in epidemiology, we propose a novel Community Health Assessment model, whose goal is to understand the vulnerability of communities to fake news spread. We define the concepts of neighbor, boundary and core nodes of a community and propose appropriate metrics to quantify the vulnerability of nodes (individual-level) and communities (group-level) to spreading fake news. We evaluate our model on communities identified using …

View, Like, Comment, Post: Analyzing User Engagement By Topic At 4 Levels Across 5 Social Media Platforms For 53 News Organizations, Kholoud K. Aldous, Jisun An, Bernard J. Jansen

Research Collection School Of Computing and Information Systems

We evaluate the effects of the topics of social media posts on audiences across five social media platforms (i.e., Facebook, Instagram, Twitter, YouTube, and Reddit) at four levels of user engagement. 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 …

A Case Study On Social Media As An Effective Management Tool, Appolloh Omolloh

Walden Dissertations and Doctoral Studies

In small businesses in the United States, specifically those with fewer than 10 employees,

leaders may be skeptical of and resistant to the use of social media in their management

operations. Management literature does not indicate clear and effective guidelines and

policies detailing small marketing firms use of social media. The purpose of this

qualitative case study was to explore the perceptions of small marketing firm leaders

about the resources and knowledge needed for effective use of social media as a

management tool. Emerson's social exchange theory grounded the study. The study

targeted owners and managers of small marketing firms …
