#01 Natural Language Processing for Healthcare - Named Entity Recognition

Dev and Doc: AI For Healthcare Podcast

In this episode we explore named entity recognition (NER) and its uses in clustering 1 million hospital inpatients, monitoring pandemics and outbreaks, automating clinical coding, enriching research cohorts, and more.

Dev&Doc is a podcast where doctors and developers deep dive into the potential of AI in healthcare.
