Quantitative Text Analysis I   

Prof. Madrid-Morales is such a friendly, well-prepared, and incredibly helpful teacher. His use of different teaching technologies makes his class a fantastic learing experience. — graduate student at the City University of Hong Kong

This course is currently fully booked!

This course provides participants with an introduction to quantitative text analysis methods used to systematically extract information from texts. It starts with an overview of traditional approaches, such as manually coded content analysis, before quickly moving on to computational methods that treat text as data. After reviewing relevant concepts in content analysis, incl. content validity and inter-coder reliability, participants learn and practice the basics of hand-coded approaches to text analysis. The second half of the course focuses on computer-assisted text analysis. Participants are introduced to text-processing techniques (e.g., tokenization, stemming, lemmatization), followed by dictionary-based approaches, such as sentiment analysis. The course combines lectures with hands-on labs that allow participants to practice and apply their newly acquired skills.

This course is the first part in a two-course sequence. Part two (cf. Quantitative Text Analysis II) covers more advanced topics, such as supervised and semi-supervised machine learning as well as topic modelling.

Detailed Description

This course provides participants with an applied introduction to basic methods of quantitative text analysis that are widely used to systematically extract information from texts. The course starts by covering traditional approaches, such as manual hand-coding, but quickly moves on to recent advances in social science methods that treat text as data and use computer-assisted techniques in their analysis.

The course begins with a review of important concepts in content analysis, such as inter-coder reliability and content validity. It then takes a closer look at manual hand-coding approaches, which have been used for decades in well-known research projects, like the Comparative Manifesto Project, that have relied on human coders to reduce content of a wide variety of texts into predefined categories. From there, the course moves to computer-assisted, dictionary-based text analysis techniques that employ computers to code large amounts of text by relying on previously built codebooks that assign individual words to specific thematic categories. In a next step, participants are introduced to various refinements to the dictionary approach, such as sentiment analysis and Wordscores. While the former allows for the study of attitudes or emotions in texts, the latter allows social scientists to automatically extract policy positions from documents, such as election manifestos or speeches.

This is an applied course for beginners and intermediate users of content analysis that provides both an overview of the theoretical foundations of quantitative text analysis and a thorough introduction to the use of computer-assisted techniques. This course is predominantly practical and applied, and it is structured in such a way that participants learn how to use these methods in their own research. It combines theoretical sessions with practical hands-on labs that allow participants to immediately apply what they learn in individual and team exercises.

This course is the first part in a two-course sequence. More advanced techniques, such as supervised and semi-supervised machine learning and topic modeling, are covered by the more the advanced Quantitative Text Analysis II course.


Prerequisites

While there are no formal prerequisites, it would be beneficial if participants were familiar with basic statistical concepts (cf. Regression Analysis) and had some experience with the statistical software R. However, participants unfamiliar with these concepts and tools will be able to effectively participate in the course.


Requirements

Participants are expected to bring a WiFi-enabled laptop computer. Access to data, temporary licenses for the course software, and installation support will be provided by the Methods School.
