Abstract

For social and political sciences, written text provide essential data for studying ideology and political discourse, conflict, sentiment and political affiliation, among many other things. With a growing availability of larger collections of text in digital form it is tempting to scale the research up in terms of the population studied (e.g. “all of twitter”), time spans (e.g. “all of the American history”), and geographical scope (e.g. “all foreign ties of China”). Computational methods for text analysis promise to aid at the scale where traditional conetnt analysis is not feasible. We will use R programming environment as a toolbox for text analysis. To “learn by doing” we will work with real text collections and will replicate some methods from the recent social research employing computational text analysis.
Learning Objectives

Learning Objectives

  • The goal of the course is to provide basic understanding on how to properly use collections of texts as quantitative evidence, and to make this knowledge practical.
Expected Learning Outcomes

Expected Learning Outcomes

  • Being able to adequately interpret and report the results of computational text analysis in research papers.
  • Understanding possibilities of the automated text analysis as well as its pitfalls and important caveats about applying statistical tests to language data.
  • Being able to apply computational methods of text analysis (e.g. analysis of word frequency and co-occurrence, document classification, topic modeling) to collections of texts.
