As the amount of publicly shared data increases, developing a robust pipeline to stream, store and process data is critical, as the casual user often lacks the technology, hardware and/or skills needed to work with such voluminous data. In this research, the authors employ Amazon EC2 and EMR, MongoDB, and Spark MLlib to explore 28.5 gigabytes of CMS Open Payments data in an attempt to identify physicians who may have a high propensity to act unethically, owing to significant transfers of wealth from medical companies. A Random Forest Classifier is employed to predict the top decile of physicians who have the highest risk of unethical behavior in the following year, resulting in an F-Score of 91%. The data is also analyzed by an anomaly detection algorithm that correctly identified a highprofile case of a physician leaving his prestigious position, as he failed to disclose anomalously-large transfers of wealth from medical companies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
