    The paper presents the results of the sentiment analysis of the US and Ukrainian presidential speeches. By means of SentiStrength and UAM Corpus Tool programs, we attempt to extract opinions and sentiments in the speeches of Donald Trump and Petro Poroshenko. The main contribution of this study is the adaptation of the SentiStrength program to the Ukrainian language by compiling a political domain glossary of the Ukrainian emotion-bearing words. Furthermore, we compare lexical means of sentiment expression in the analyzed texts.
