A Cognitive Pragmatic Analysis of Conceptual Metaphor in Political Discourse Based on Text Data Mining

As a cognitive mechanism and thinking mode of human beings, conceptual metaphor is not only a way to make the world order, but also one of the main basic ways of human existence. Scholars at home and abroad have done a lot of research on conceptual metaphor and ideology in political discourse. But the research results, especially the domestic research results are not very rich. We should expand the scope of the number and types of corpus, and adopt a variety of methods to continue to deepen. From the perspective of cognitive pragmatics, based on Lakoff's conceptual metaphor theory and framework theory, this paper explores the framework of conceptual metaphor in political speeches from the official website of the Ministry of foreign affairs. This paper explores the powerful appeal of metaphor in political discourse and its influence on the audience's cognition and acceptance. This paper summarizes the similarities and differences of conceptual metaphors in Chinese and American political discourses, aiming to deepen the understanding of metaphors in political discourses, so that learners can better understand the characteristics of political language.
