Social Computing and Health Informatics: Mining Big Twitter Data in regard to Diabetes, Diet, Exercise, and Obesity


Amir Karami, PhD
Assistant Professor, School of Library and Information Science

Social media provide a platform for users to express their opinions and share information. Understanding public health opinions on social media, such as Twitter, offers insights into the thinking of the general public on important health issues (e.g., diabetes, diet, exercise, and obesity). The goal of this research is to analyze the characteristics of public opinion about diabetes, diet, exercise, and obesity as expressed on Twitter. A multi-component semantic and linguistic framework was developed to collect Twitter data, discover topics of interest within diabetes, diet, exercise, and obesity, and analyze the topics.

Amir Karami, PhD, is an Assistant Professor in the School of Library and Information Science, as well as Faculty Associate for the South Carolina SmartState Center for Healthcare in the Arnold School of Public Health. He received his PhD in Information Systems from the University of Maryland, Baltimore County. Dr. Karami’s work focuses on big data and text mining, health and medical informatics, and social media analysis to understand various health-related behaviors and outcomes.

This event is free and open to the public.
Light refreshments will be served.
