Occupation information has been collected from individuals for a variety of purposes, including epidemiologic studies. This information is typically asked using open-ended questions. However, using this data requires mapping the free-text responses to standardized occupation classification (SOC) codes, which is usually done manually by expert coders. Dr. Friesen will describe the development and validation of a computer algorithm to code free-text job descriptions to SOC codes. Coded job descriptions can be used by researchers to identify disease and injury patterns by occupation group or as the starting point for exposure assessment strategies, such as the use of job-exposure matrices.
