Workshop: Data Visualization for Corpus Linguistics via Shiny Framework

Olga Scrivner, profile picture
Olga Scrivner

This document discusses using the Shiny framework to build interactive web applications for data visualization in corpus linguistics. It provides an introduction to visual analytics and reactive web frameworks. It then describes the Shiny application framework, including its reactive architecture and benefits. The document demonstrates building a basic Shiny app, adding inputs and outputs, and linking them. It also provides resources and steps for installing R and RStudio, and developing a Shiny app to visualize and summarize a corpus linguistics data set.
