Most digital content, whether it be thousands of news articles or millions of social media posts, is too large for the naked eye alone. Often, the advent of immense datasets requires a more productive approach to labeling media beyond a team of researchers. This book offers practical guidance and Python code to traverse the vast expanses of data—significantly enhancing productivity without compromising scholarly integrity. We’ll survey a wide array of computer-based classification approaches, focusing on easy-to-understand methodological explanations and best practices to ensure that your data is being labeled accurately and precisely. By reading this book, you should leave with an understanding of how to select the best computational content analysis methodology to your needs for the data and problem you have.

This guide gives researchers the tools they need to amplify their analytical reach through the integration of content analysis with computational classification approaches, including Machine Learning and the latest advancements in Generative Artificial Intelligence (AI) and Large Language Models (LLMs). It is particularly useful for academic researchers looking to classify media data and advanced scholars in mass communications research, media studies, digital communication, political communication, and journalism.

Complementing the book are online resources: datasets for practice, Python code scripts, extended exercise solutions, and practice quizzes for students, as well as test banks and essay prompts for instructors.

From here we will assume that you have a fundamental working knowledge of manipulating data in Python. If you are not a coder, we’ll discuss emerging generative AI tools that can help you code. Either way, join me as I unpack the various types of classification tools that are at our disposal today. They will guide you in better understanding and working with computational folks who can help you “scale” your content analysis across large datasets.
