TThe role of mass media in society keeps the problem of manipulative influence
distinction and the contiguous phenomena, chief among which is objectivity
and authenticity of news items, current. The research provides a detailed study
of the information broadcasting mechanisms in the media area, defines the
problems, impeding an impersonal reproduction and disclosure of information,
clarifies the verification methods, and gives their topology. In this research, we
examined how the mass media of different countries presented the same event
to the public. The publications of four mass media, concerning such an event as
the withdrawal of the United Kingdom from the European Union (Brexit), have
been determined as an object of the analysis. The chosen mass media refer to
the countries, which are not the direct participants of that process: Russia, the
USA, and Ukraine. D. Brewer’s criteria were used to define the objectivity of the
news items. A relative sentiment of the news, which became the objective
analysis basis, has been identified using linguistic rate with Eureka Engine
intelligence system. The obtained results predominantly confirmed the
hypothesis, that the mass media of different countries would represent the
process of the UK withdrawal from the EU according to the country’s policy and
interpret the facts in their favor. All the four mass media demonstrate the
partiality when broadcasting the current situation in the matter of Brexit. The
concepts being the semantic kernel elements of mass media publications have
emotional coloring. The sentiment analysis of the publications resulted in the
conclusion that only one of the four mass media gave a neutral assessment of
the Brexit situation
