| As a universal but special language phenomenon,euphemisms play a significant communication function in daily life.The correct understanding and use of euphemisms can not only assist us to build good personal image and deal with interpersonal relationships,but also help us better understand the culture of other countries and perceive the diversity of cultures in cross-cultural communication.Traditional studies on Russian euphemisms mainly focus on the definition of euphemism,the means of expression,the relationship between euphemism and taboo,and the translation research of euphemism in a cross-cultural context.There are only a few studies on the definition,classification,function and context dependence of euphemisms from the perspective of pragmatics.Moreover,along with the fast development of artificial intelligence and natural language processing techniques,the research on Russian euphemisms has not been explored and developed well,to meet the demand of the social development in the era of big data.Although some researchers have been focusing on the study of Russian language based on the natural language processing techniques,there is no relevant interdisciplinary research projects so far,particularly for Russian euphemisms.Therefore,in this thesis,by adopting methods such as comparative analysis,classification,induction,and context analysis,we mainly explore the classification and functions and other relevant elements of euphemisms,from the perspective of the pragmatics and the relevant theories.Meanwhile,in order to meet the new demand of the interdisciplinary study of linguistics and computer science,in this thesis,we also propose a method for euphemism research,based on the natural language processing techniques.The interdisciplinary study is not only beneficial for us to understand and use euphemisms from the perspective of pragmatics,but also provides novel insights for the future research directions and methods of Russian euphemisms in the era of big data.This is one of the most important contributions of this thesis.In this thesis,we first introduce some mainstream definitions of euphemism in linguistics.By comparing and analyzing the shortcomings of these definitions,we select the recommended definition of euphemisms in this thesis,based on the cooperation and politeness principles.The main focus of this thesis is the classification and function of Russian euphemisms in the pragmatic aspects.Through comparative analysis of the traditional classification methods of Russian euphemisms,we propose a context-based euphemism classification method,based on the context theory in pragmatics and the context dependence of euphemisms.The euphemisms are divided into four categories:political euphemisms,economic euphemisms,social life euphemisms and euphemisms in literature.Secondly,through the analysis of euphemism examples,we find that euphemism has a strong communicative function,which can be divided into taboo function,polite function,cover-up function,and humor functionAt last,we discuss the potential natural language processing-based methods for Russian euphemism research,from the aspect of pragmatics.We put forward the necessity of constructing Russian euphemism language resources and datasets.Meanwhile,we present a two-step-based method for constructing Russian euphemism language resources,by referring to the existing methods in literature.The first step is to construct a corpus of Russian euphemisms,and the second step is to perform semantic annotation on Russian euphemisms in the corpus assisted by computers.The concluding part summarizes the full thesis.At the same time,some problems are also proposed in this thesis,which are worth further discussion in the future.It should be noted that,the proposed artificial intelligence-based method for Russian euphemism research is ideal,which still needs to be continuously evaluated and improved in practice. |
