Computational Content Analysis of Negative Tweets for Obesity, Diet, Diabetes, and Exercise
Social media based digital epidemiology has the potential to support faster
response and deeper understanding of public health related threats. This study
proposes a new framework to analyze unstructured health related textual data
via Twitter users' post (tweets) to characterize the negative health sentiments
and non-health related concerns in relations to the corpus of negative
sentiments, regarding Diet Diabetes Exercise, and Obesity (DDEO). Through the
collection of 6 million Tweets for one month, this study identified the
prominent topics of users as it relates to the negative sentiments. Our
proposed framework uses two text mining methods, sentiment analysis and topic
modeling, to discover negative topics. The negative sentiments of Twitter users
support the literature narratives and the many morbidity issues that are
associated with DDEO and the linkage between obesity and diabetes. The
framework offers a potential method to understand the publics' opinions and
sentiments regarding DDEO. More importantly, this research provides new
opportunities for computational social scientists, medical experts, and public
health professionals to collectively address DDEO-related issues.Comment: The 2017 Annual Meeting of the Association for Information Science
