The SAGE Handbook of Research Methods in Political Science and International Relations offers a comprehensive overview of research processes in social science - from the ideation and design of research projects, through the construction of theoretical arguments, to conceptualization, measurement, and data collection, and quantitative and qualitative empirical analysis - exposited through 65 major new contributions from leading international methodologists. Each chapter surveys, builds upon, and extends the modern state of the art in its area. Following through its six-part organization, undergraduate and graduate students, researchers and practicing academics will be guided through the design, methods, and analysis of issues in Political Science and International Relations: Part One: Formulating Good Research Questions and Designing Good Research Projects; Part Two: Methods of Theoretical Argumentation; Part Three: Conceptualization and Measurement; Part Four: Large-Scale Data Collection and Representation Methods; Part Five: Quantitative-Empirical Methods; Part Six: Qualitative and Mixed Methods.

Classification and clustering
Sarah B. Bouchart

Text serves as a critical source of political data – comprising everything from official statements to news coverage, social media responses and legal documents – that is also increasingly accessible via large-scale digitization and open-source analytical tools. Perhaps even more critically for political science, classifying and characterizing these complex data facilitates inferences about policies, norms, strategic communication and the ideological landscape. Much like typological research that has a long lineage in the social sciences, classification using text data allows us to make fundamental claims about the nature of discourse and communication in politics that generalize across space and over time.

This chapter examines both supervised and unsupervised learning techniques for classification and clustering ...
