Science Colloquium Talk Title: Language and Ideology in Congress Speaker: Bei Yu, Assistant Professor, Syracuse University Location: 301 College Ave., Seminar Room Abstract: Ideology has been an important concept in political opinion and behavior analysis. Political scientists used to use voting records for ideology analysis. In recent years scholars from multiple disciplines have started to use language technologies to analyze ideology in large amount of political speeches. The research presented in this talk used machine learning and corpus linguistics techniques to discover the linguistic footprints of ideology in Congressional speech. This study reveals the characteristics of political opinion expression, such as opinions carried by seemingly neutral nouns. A longitudinal study of the Congressional speech of the past 20 years also provides new evidence that the Congress is becoming more ideologically divided.
