Research On The Cognitive Model Of The Preposition за Based On The Russian Corpus

Language is an evolving dynamic organic system.In the long-term development process,a word form gradually extends multiple meanings from a single meaning,forming a lexical polysemy.This phenomenon is one of the most basic characteristics of natural language.Therefore,the storage,meaning linkage and extension mechanism of meaning in the human brain has become an urgent need for cognitive linguistics research.In the language,the preposition is a typical polysemous word.It is not only rich in semantics,but also the result of conceptualization of the interaction between human and the world space-body interaction.It expresses the most basic human grasp in the initial stage of cognitive behavior.Concepts,so the study of prepositions can help us better explore the basic cognitive styles of human beings and reveal the cognitive mechanisms of meaning storage,connection and extension in the human brain.As a preposition with rich semantics,За is the research object of this thesis.This paper takes the various examples(including 1000)of the preposition за extracted from the Russian national corpus as the corpus,and uses the image schema theory,cognitive model theory and cognitive context as the theoretical basis,and the preposition за.The cognitive model and the context activation law are systematically and comprehensively analyzed.This thesis consists of three parts: introduction,main part and conclusion.The introduction provides an overview of the current state of the problem under study,sets a goal,reveals the significance of the results obtained,identifies the object,methods and novelty of the research.The main part is divided into six chapters:The first chapter provides a brief overview of the scientific literature on the topic of research,analyzes the previous results of scientific research on this topic and determines the direction of research in this dissertation.The second chapter introduces the theoretical basis of this thesis: image schema theory,cognitive model theory and cognitive context,which provides theoretical support for the cognitive research of preposition за.The third chapter classifies and filters the corpus containing the preposition за in the Russian national corpus,and extracts 1000 corpora for further statistics and classification,which serves as the basis for the extraction and induction of the cognitive model.The fourth chapter divides and analyzes the static image schema cognitive model and the dynamic image schema cognitive model of the preposition за according to the statistical results,and explains the cognitive mechanism of the preposition за semantic generation.The fifth chapter analyzes the metaphorical cognitive model derived from the Russian preposition за image schema cognitive model based on the statistical results,and explains the cognitive mechanism of the semantic expansion of the preposition за.The sixth chapter discusses the influence of various participating factors on the activation of the preposition за cognitive model in cognitive context,and reveals the role of cognitive context in the change and adjustment of the semantic corresponding cognitive model.Conclusion: Summarize the full text and draw conclusions.
