The culture of modern social communication in the information society includes a dialogue of cultures. Intercultural interaction involves mutual exchange and enrichment of cultural meanings for all participants in international communication. Lexicographic sources are the recorders of linguistic cultural heritage and the acquired cultural experience of intercultural interaction. The problems of periodic lexicography of cultural concepts, the need for further development of cultural dictionaries and thesauri, continuation of the traditions of domestic lexicography, analysis of multifaceted linguacultural information remain relevant. New national and cultural situations are recorded in the four-language thesaurus created by the authors aiming to preserve and pass on to future generations of the information society our rich cultural heritage, imprinted in culturonyms. To analyze cultural concepts, the method of included observation, a comprehensive comparative analysis of the culture of publishing dictionaries and thesauri, and high-quality data processing were used. When constructing the design of the dictionary entry, the method of descriptive and lexicographic analysis of dictionaries and thesauri, the heuristic method were used. The new thing in the creation of the thesaurus is the inclusion by the authors of cultural and translation comments in the dictionary entry, a separate part of the entry “for translation and commentary” as a heuristic dialogue. The authors attach great importance to the art of conveying the meanings of cultural words of the Russian, English (British and American versions), Belarusian, and French languages. The thesaurus is based on the principles of active lexicography, in which cultural meanings are seen as keys to these languages. The authors analyzed different types of domestic and foreign dictionaries and thesauri for traditions and methods of lexicography of linguistic and cultural information. The result of the study was the creation of a thesaurus, a specialized translation publication that included value cultural concepts of the Anglo-Saxon and East Slavic cultures, and French cultures. The translated thesaurus of cultural names and realia will serve as a motivational resource for promoting the study of Russian as a foreign language for representatives of other cultures.
