Julia Silge - Text Mining Using Tidy Data Principles

Описание к видео Julia Silge - Text Mining Using Tidy Data Principles

Unstructured, text-heavy data sets are increasingly important in many domains, and tidy data principles and tidy tools can make text mining easier and more effective. In this talk, we will explore how you can manipulate, summarize, and visualize the characteristics of text using R packages from the tidy tool ecosystem; these tools extend naturally to many text analyses and allow analysts to integrate natural language processing into effective workflows already in wide use. We will discuss how to implement approaches such as sentiment analysis of texts and measuring tf-idf to quantify what a document is about.
