Data Preparation For Social Network Mining And Analysis, Yazhe Wang

Dissertations and Theses Collection (Open Access)

This dissertation studies the problem of preparing good-quality social network data for data analysis and mining. Modern online social networks such as Twitter, Facebook, and LinkedIn have rapidly grown in popularity. The consequent availability of a wealth of social network data provides an unprecedented opportunity for data analysis and mining researchers to determine useful and actionable information in a wide variety of fields such as social sciences, marketing, management, and security.

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 …

"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 …

Microbloggers’ Motivations In Participatory Journalism: A Cross-Cultural Study Of America And China, Jue Rui

Doctoral Dissertations

This phenomenological study focuses on the motivations of participatory journalists contributing on microblogs such as Twitter and Weibo. Although online user behavior and motivations have been studied before, few studies have examined motivations of participatory journalists from their own perspective. Moreover, this study is one of the few to explore participatory journalists across different cultures (U.S. and China). The author conducted a total of 13 in-depth interviews with participatory journalists on microblogs from both countries and used a qualitative analysis method to identify the themes and patterns that emerged. Motivations such as earning respect, technology early adoption, self-expression, relationship building, …

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 …

Several linear regression analyses found that student-athletes' perceived control of private information flow on Twitter and their perceptions of choice significantly predicted the total months of using Twitter. Perceived control of private information flow on Twitter also predicts how many times they will check Twitter. Finally, student-athletes' perception of boundary ownership/linkage also predicts the total amount minutes spent …

Testing The Message: Making Sense Of Converging Multimodal Messages In A Foodborne Illness Outbreak, Bethney A. Wilson

Theses and Dissertations--Communication

The goal of risk and crisis communication is to reduce and contain the harm inherent in a threat. In order to achieve this goal, risk and crisis scholars call for continued testing of messages surrounding these events; specifically, messages that address the needs of the at-risk message receiver. Previous scholarship suggests that these messages should include adapting and instructing information (Coombs, 2012), and should be designed using pedagogically sound instructional approaches (Frisby, Sellnow, Sellnow, Lane, & Veil, 2011; Sellnow & Sellnow, 2010). In order to meet this call, this dissertation tested an instructionally sound message that includes both adapting and …
