Introduction to NLP and Health Data

February 10 @ 9:00 am - 11:00 am

This workshop is held as part of the Health Data Science Day at the UC Davis Medical Center in Sacramento. Registration for this event is required and spaces limited.

Registration: https://tinyurl.com/UCDHealthDataScienceDay

Description:
This workshop covers an introduction to natural language processing (NLP) and caveats for its application to health data. Using the R programming language we will introduce the basics of text processing and demo how to calculate common metrics including word frequencies, term frequency-inverse document frequency (TFIDF), and principal component analysis (PCA) to explore important words and group similar documents. We will also introduce more advanced NLP topics (sentiment analysis, topic modeling, etc.) and discuss classical versus deep learning approaches, as time permits. Learners with proficient R skills are encouraged to code along.

Learner objectives:
* explain natural language processing in lay terms
* give examples of NLP applications for research
* evaluate particular challenges posed by working with health data
* describe key text mining and NLP metrics for assessing word importance and document similarity
* identify where to go to learn more!

Prerequisites:
No prior NLP or text mining knowledge is necessary. Learners interested in coding along are expected to have prior experience using R, be comfortable with basic R syntax, and to have it pre-installed and running on their laptops. Bring your laptop with access to the local wireless network (UCDMC or guest).
