The article discusses the notion of concordance as a kind of dictionary of compatibility, which allows to analyze different contexts, to deduce shades of word meaning on their basis, to model semantic fields of correlated words in different languages. The aim of the article is to reveal the methodology of using the technologies of composing corpora of texts and concordances to build a nominative field of the concept HEALTH in English and Ukrainian media texts. The study was based on media texts on medicine, health and coronavirus in English and Ukrainian media texts (newspapers and magazines: USA Today, The Wall Street Journal, The New York Times, Los Angeles Times, The Washington Post, Vysokyi zamok, Ukrainska pravda; online edition: www.bbc. com/ukrainian/, www.bbc. com/news, time.com/, www.nytimes.com/, www.who.int; Gazeta.ua, Holos Ameryky, Hromadskyi prostir, Ukrainskyi tyzhden, Yevropeiska pravda, Hromadske.ua, Ukraina moloda and others). It is illustrated how concordance reflects all cases of use of words in this or that text, corpora of texts; the keywords of the researched concept are searched and the frequency of their use is determined. The use of concordance and corpus technologies (works by A. McCarthy and R. Carter, O'Keefe) is usually associated in linguistics with the study of the semantics of language units based on the calculation of word frequency, keywords, cluster analysis, etc., lexical and grammatical profiles. Work of users with the case is carried out by means of the specialized software – case managers who provide various opportunities on reception of the necessary information from the case. Concordance programs are used in a variety of areas: language learning and learning, language data search and analysis, translation and language engineering, corpus linguistics, lexicography, content analysis in accounting, history, marketing, music, politics, geography, journalism, and more. With concordance, you can create indexes and glossaries, calculate the frequency of use of a word, compare different uses of the word, analyze keywords, find phrases and idioms, create a concordance of one author, and so on. The main task of the concordance is to display all cases of use of the word registered in some texts. The possibility of realization of lexical meaning in the text is demonstrated, which helps to determine the role of lexical unit in the formation of textual conceptual structure.
