Abstract :
We assess the relative frequency that lexical items defined in the pyConTextNLP package occur within radiology, history and physical, and emergency department texts. While we found significant disparity in term frequency between the text types nearly half of the lexical items were not found in any of the texts indicating that significant pruning of the lexical knowledge base could be attempted. However, the study is limited by the small number of texts studied.
