A CiteSpace-based analysis of the application of Critical Discourse Analysis in news discourse

Critical Discourse Analysis/Studies has been applied in the study of news discourse for more than 30 years. In order to gain an in-depth understanding of the research in this field, this article uses the Web of Science core database to investigate their evolution and envision of the application of CDA/CDS in news discourse. Moreover, CiteSpace is employed to draw visualization maps of scientific knowledge of this field, hoping to provide the meaningful guidance for the later research. The results are as follows: (1) The diversification and multi-dimension of theoretical approaches and analytical methods is a highlight of CDA applied in news discourse; (2) Various theories of other disciplines combined with CDA have been embraced by news discourse such as journalism, ecology, politics, sociology, and cognitive psychology, which shows the advancement and diversification of interdisciplinary trends in news discourse; (3) The application of CDA in news discourse covers various research domains from people’s livelihood issues to national strategic issues; (4) The availability of emerging corpus analysis tools has helped the application of CDA in news discourse to spur on further (critical) discourse excursions with corpora, promoting the comprehensiveness and accuracy of the research advances in this field.
