Title: Data-centric solutions to leverage social media big data for health-related tasks

Social media has emerged as an important source of patient-generated health information over recent years. However, the many challenges associated with social media data mining act as barriers to efficiently utilizing the knowledge in such resources. Effectively leveraging social media data for health-related tasks requires the development of sophisticated data processing pipelines involving natural language processing and machine learning. In this talk, I will present our work on developing such pipelines for the problem of substance use and substance use disorder. Overdose-related deaths caused by substance use are a national crisis in the United States, and despite the enormity of the problem, there is a lack of surveillance mechanisms that would enable investigations on the factors contributing to substance use, the natural history of the individuals who develop substance use disorders, and the characteristics of the populations affected (eg. age and gender) by substance use. I will present our current infrastructure that involves manual annotation, supervised classification, information extraction, and combining them with social media meta-data such as geolocation. I will present our various data characterization methods and their validations against traditional sources of data such as the CDC Wonder database and the National Survey on Drug Use and Health. I will also outline future research opportunities in this space--particularly for social media-based interventions and for integrating social media with other sources of data.
