REPRESENTATION OF THE CONCEPT "EXPERT" IN BUSINESS JOURNALISTIC DISCOURSE
He author analyzes the semantics of the concept “expert”; identifies lexical and grammatical ways of its representation; the object of the research is the contemporary Russian business journalistic discourse. The social frames of a business discourse are defined by the space of professional, daily and mass media business communication. The concept “expert” is investigated as one of the basic concepts in the business picture of the world. The concept is based on three criteria of trust in information: validity, personalization and authority. The methodological foundation of research is made up by cognitive linguistics (E. S. Kubryakova, Z. D. Popova, I. A. Sternin, G. N. Manayenko), semantics theory (N. D. Arutyunova, E. V. Paducheva), and discourse theory (A. P. Chudinov, D. V. Grechikhin). In the course of analysis of a specific kind of the social picture of the world - the business picture of the world - the author correlates local and universal, subjective and objective aspects in the semantics of the concept. The concept “expert” functions as the agent in a standard proposition: ‘somebody (an authority) states a competent judgment about an object’. This proposition can be also realized in legal, medical, technical, scientific and professional discourses. The origin of the meaning of the word “expert” comes from the meanings “testing”, “trying”, “checking” and “experience”. On the one hand, the knowledge of the expert appears as “true”: reliable, exact and verifiable. On the other hand, an expert is a person, and in the media discourse it is the main source of information. Therefore along with the logical criterion of “truth” the criterion of “personalization” (personal responsibility for the knowledge) becomes rather significant. It is in the “language type” of an “expert” that the third important criterion, authority, is realized. Thus, connecting these three criteria, this concept carries out the function of logic-ethical “legitimization” of the business picture of the world.
