Abstract

For social science research, written text provide essential data for studying media and political discourse, ideology, conflict, sentiment and political affiliation and many other things. With a growing availability of larger digital collections of texts it is tempting to scale the research up in terms of the population studied (e.g. “all social media users of a town”), time spans (e.g. “all of the Post-Soviet history”), and geographical scope (e.g. “all educational migration in Russia”). Computational methods for text analysis are expected to help where traditional content analysis is not feasible. During the course we will cover basic word statistics, various exploratory methods, supervised and unsupervised modeling of text phenomena. Data Culture level (0.2.2 — Basic level: Programming + Data Analysis) will be achieved through studying methods of preprocessing and transformation of text data, as well as supervised and unsupervised methods of text analysis, such as topic modeling, classification, semantic analysis.
Learning Objectives

Learning Objectives

  • 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.
  • 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
  • Being able to apply word embedding and clustering methods to downstream tasks, such as sentiment analysis, ideological scaling etc.
  • Understanding multidimenional representation of lexical meaning and the role of the dimensionality reduction.
  • Understanding possibilities of the automated text analysis as well as its pitfalls and important caveats about applying statistical tests to language data.
