Extracting Disease Severity Measures from Unstructured Clinical Notes Using Spark NLP
While disease severity dictates how virtually all diseases are managed and treated, disease-specific severity measures are seldom available in structured clinical data. Therefore, an application that could extract such severity measures from clinical notes would be valuable to understand disease activity in patients and subsequent disease management. In this talk, the speakers demonstrate how Spark NLP can be used to extract severity measures for a variety of diseases using a question-answering system and natural language processing. The speakers describe how a pretrained question-answering model can be imported into Spark NLP, how metadata on particular severity measures can be imported into a Spark session, and how the model can be applied to unstructured clinical notes to extract severity measures for any disease.
