This article considers constructing an intelligent information system to study lexical innovations in English-language Eurointegration discourse. The expediency of developing such a system given the Eurointegration course of our state is substantiated. The advantages and disadvantages of the developed system are described. This article is topical, presenting the research of a multidisciplinary character, namely combining issues of applied linguistics, discourse analysis, lexicology, and information technologies. The primary value of the proposed study is a practical one. The article describes the constructed intelligent information system for analysing linguistic innovations in English-language Eurointegration discourse relating its advantages and disadvantages. The theoretical background of the research takes into account some central notions of modern theoretical linguistics, such as the discourse and lexicology theory with a focus on lexical innovations. Also, the article considers the development of a program for the analysis of goods by their comments, namely the goods that are posted on the Internet in the form of posts on social networks. Current methods of keyword recognition, comments' clustering, the topic's recognition, the essence and ideas of sentences, and current practices of visualising a large amount of data in a clear and simple form are considered.
