Summary: | De-identification is the process of removing 18 protected health information
(PHI) from clinical notes in order for the text to be considered not
individually identifiable. Recent advances in natural language processing (NLP)
has allowed for the use of deep learning techniques for the task of
de-identification. In this paper, we present a deep learning architecture that
builds on the latest NLP advances by incorporating deep contextualized word
embeddings and variational drop out Bi-LSTMs. We test this architecture on two
gold standard datasets and show that the architecture achieves state-of-the-art
performance on both data sets while also converging faster than other systems
without the use of dictionaries or other knowledge sources. |
