One of the major sociological research interests has always been the study of political discourse. This literature review gives an overview of the most prominent topics addressed and the most popular methods used by sociologists. We identify the commonalities and the differences of the approaches established in sociology with corpus-driven approaches in order to establish how parliamentary corpora and corpus-based approaches could be successfully integrated in sociological research. We also highlight how parliamentary corpora could be made even more useful for sociologists. Keywords: parliamentary discourse, sociology, parliamentary corpora
