Description

We show how topic modeling techniques can be used in conjunction with the ClarityNLP platform to extract patient-level features that are unlikely to appear in structured data (e.g., sociodemographic characteristics; socioeconomic characteristics; history of substance abuse) from unstructured clinical notes. These features can be used as input during the development of patient-level predictive models, and/or to identify patients that are eligible for participation in clinical trials.

Describe the new knowledge and additional skills the participant will gain after attending your presentation.: Attendees will better understand how to leverage unsupervised and semi-supervised, human-in-the-loop machine learning techniques, such as topic modeling, to extract information from unstructured clinical notes for the purpose of feature engineering and/or iterative computational phenotype development.
