Abstract

The research presented in this thesis explores ways to enhance Natural Language Processing techniques from the ground up in order to make them better suited to process clinical text. Two fundamental building blocks are developed for the better representation and mining of clinical text. These blocks are subsequently used to address the problem of clinical coding - the process of assigning standardized codes based on discharge notes to assist with billing, analytics and subsequent decision making. The newly developed method of coding is unsupervised, i.e., it does not need to be trained on labelled coding data. Unlike contemporary deep learning models, this method also offers a high degree of interpretability, being able to exactly pinpoint the text snippet that lead to the assignment of a clinical code.
