This workshop will be held live on November 30, December 7th and 14th 2021 (5:30PM-8:00PM)
This workshop will provide an introduction to working with text data in R and explore various approaches to analyzing text data. The first session will cover principles for wrangling text data as well as some basic text mining applications. The subsequent two sessions will delve into specific techniques to enable automated analysis of text data. The workshop will include three two-hour sessions with the following learning objectives:
- After Session 1: Introduction to Working with Text learners will be able to:
- Read text data into R and prepare it for analysis;
- Understand and select from various options in preparing text, such as stemming, lemmatization, term frequency weighting, term frequency-inverse document frequency weighting (tf-idf), and tokenization;
- Conduct simple text mining to explore content of a text corpus.
- After Session 2: Unsupervised Approaches to Text Analysis, learners will be able to:
- Describe how unsupervised approaches can be used to identify clusters of related documents;
- Process text data to prepare for unsupervised analysis;
- Build, train, and evaluate models for text clustering;
- Interpret outputs of clustering algorithms.
- After Session 3: Supervised Approaches to Text Analysis, learners will be able to:
- Describe how supervised approaches can be used to develop text-based models for multi-class classification;
- Process text data to prepare for supervised analysis;
- Build, train, and test models for text classification.

Simultaneous access to two screens is highly recommended for best learning experience. Examples include one computer with two screens, two computers, one laptop and one tablet, etc.
Although no grades are given for courses, each participant will receive Continuing Education Units (CEUs) based on the number of contact hours. One CEU is equal to ten contact hours. Upon completion of this course each participant will receive a certificate, showing completion of the workshop and 0.7 CEUs.
