豆瓣
A practical introduction to the analysis of texts, networks, and images with code examples in Python and R
Wouter van Atteveldt / Damian Trilling …
简介
This book is aimed at students and (aspiring) practitioners of computational social science, especially related to the analysis of digital communication. With this book and the accompanying code examples and video tutorials, you can learn data wrangling, machine learning, text analysis, and more. All examples are given side-by-side in Python and R, allowing you to pick your favorite language but also showing the differences and many similarities at a glance.
