There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
-----------
Traditional social science methods rely on labor and time intensive methods to transform qualitative data into quantitative representations of phenomena of interest. In order to rapidly conduct such social scientific research on larger scales, social science researchers need to incorporate computational tools and methods. The Computational Social Science (CSS) paradigm offers useful perspectives for gaining insights from large-scale analyses of demographic, behavioral, social network, and technology-mediated social communication data to investigate human activity, relationships, and other phenomena at multiple scales (e.g., individual, organizational, community, social group, and societal). Human Centered Computing (HCC) complements CSS by offering foundational science for designing, developing, evaluating, and deploying computational artifacts that better support the human endeavors associated with the conduct and practice of CSS research. This dissertation demonstrates theoretical, methodological, and technological contributions resulting from blending traditional social science with computational approaches for the study of human behavior.
Following the CSS paradigm, I build theoretically-informed representations of social constructs—e.g., models of interpersonal relationships and the complex cognitive processes related to human perceptions of sentiment and bias—then use HCC principles to develop and evaluate computational tools that implement those models for the purpose of aiding social science research oriented around large-scale content analysis (e.g., of content from social media networks, product and movie reviews, and newspapers). I do this first by presenting insights from characterizing, quantifying, and analyzing persistent social tie formations in a popular online social network, Twitter. Next, I delve deeper into the analysis of text-based social media content by applying human-centered methods to develop, evaluate, and deploy a computational model (called VADER) to support large scale sentiment analysis of online content from social media, news articles, and user-generated reviews of movies and products. I support the development and evaluation of VADER (and similar CSS- and HCC- inspired technology) by further refinement of a generalized methodological framework for conducting high-volume human evaluations/validation on large scales without jeopardizing qualitative data analysis quality. Finally, I apply the methods, tools, and techniques described above to define and develop a computational model to detect and quantify the degree of perceived bias in journalistic news stories.
In short, this dissertation presents the confluence of computational social science perspectives for theory building and application with human-centered development, evaluation, and deployment of computational tools and methods to support the large scale systematic and (unobtrusive) study of social phenomena as observed via technology-mediated communications and interactions in online content.
