Nicole Baerg

In this 1-hour long project-based course, you will learn how to explore presidential concession speeches by US presidential candidates over time, looking specifically at speech length and top words and examining variation by Democrat and Republican candidates. You will learn how to import textual data stored in raw text files, turn these files into a corpus (a collection of textual documents) and tokenize the text all using the software package quanteda. You will also learn how to extract useful information from filenames and how to use this information to generate visualizations of textual data using the stringr and ggplot2 packages.

Reviews summary

Practical text analysis with r

This short, project-based course aims to provide a practical introduction to exploratory text analysis in R, specifically using the quanteda, stringr, and ggplot2 packages. Designed for beginners in text analysis with basic R knowledge, it focuses on a real-world dataset of presidential speeches. It is likely to be valued for its hands-on learning approach and ability to quickly convey core concepts. However, its brief 1-hour duration suggests it serves as a foundational overview rather than an in-depth study.

Utilizes presidential concession speeches for practical application.

"The focus on US presidential concession speeches provides a unique, relatable dataset for the project."

"While interesting, I might prefer a project with broader applicability to different industries or text types."

"I'm interested in the political data, but other learners might want to see different text examples."

Teaches key text analysis using quanteda, stringr, ggplot2.

"I look forward to learning how to use the quanteda package effectively for text analysis."

"It's great that it integrates stringr and ggplot2 for visualization alongside text processing."

"I'll learn how to transform raw text into a corpus and tokenize it efficiently using R."

Designed for those new to text analysis with basic R skills.

"I need an introduction to text analysis, and this course assumes no prior knowledge in that area."

"Since I have a basic understanding of R, this seems like the perfect next step for me."

"I'm confident I can follow along given my foundational R skills in R."

Provides a fast, hands-on start to text analysis.

"I appreciate that this is a 1-hour project; it's perfect for a quick skill acquisition."

"The project-based format seems ideal for immediately applying what I learn."

"I expect to get a solid practical understanding of text analysis basics in a short time."

The short duration suggests a focus on breadth over depth.

"Being only one hour, I expect it will cover foundational concepts but not advanced techniques."

"I understand this won't be a comprehensive course, but rather an introductory guided project."

"It's unlikely to delve into complex topics like machine learning for text, given its scope."
