Dr. Choi has been active in the field of Natural Language Processing (NLP). He has presented many
state-of-the-art NLP models that automatically derive various linguistic patterns from unstructured
text. These models are publicly available through the cloud-based NLP platform called ELIT that Dr.
Choi has created to promote academic and industrial research. He has also introduced novel machine
comprehension models to identify personal entities and infer explicit and implicit contexts in
multiparty dialogue, which can be used to build question answering systems on daily conversion.
For medical informatics, Dr. Choi has developed innovative models to classify severity levels on
radiology reports using deep neural networks and detect early stages of Alzheimer’s disease using
meta-semantic analysis, which show similar accuracy as human experts in those domains.
