Tiivistelmä

We introduce a multi-label classification system for the automated assignment of diagnostic codes to radiology reports. The system is a cascade of text enrichment, feature selection and two classifiers. It was evaluated in the Computational Medicine Center’s 2007 Medical Natural Language Processing Challenge and achieved a 87.7% micro-averaged F1-score and third place out of 44 submissions in the task, where 45 different ICD-9-CM codes were present in 94 combinations. Especially the text enrichment and feature selection components are shown to contribute to our success.  Our study provides insight into the development of applications for real-life usage, which are currently rare.
