Machine Learning to Code Work-Related Injury Narratives - 2020

The National Institute for Occupational Safety and Health (NIOSH) collects free-text injury narratives in a variety of data-sources. These narratives, often composed by the injured worker themselves, describe the circumstances leading to a work-place injury. In order to create basic surveillance reports to aid future preventative strategies, these narratives need to be categorized into a standardized coding system that identifies the cause of the injury. Traditionally, this was done manually however, recent efforts were made to automate this process. About 8 years ago, NIOSH developed an auto-coder that read a narrative and assigned it to the appropriate causation category. It was estimated that this auto-coder was about 82% accurate. This auto-coder relieved the manual burden of reading thousands of claims and was often more consistent in its designations. The purpose of this project was to host a public competition to improve upon NIOSH's current algorithm."
