    (Lviv Politechnic Publishing House, 2019-04-18) Shanidze, Olexandr; Petrasova, Svitlana; National Technical University "Kharkiv Polytechnic Institute"
    This paper proposes the algorithm for automatic extraction of semantic relations using the rule-based approach. The authors suggest identifying certain verbs (predicates) between a subject and an object of expressions to obtain a sequence of semantic relations in the designed text corpus of Wikipedia articles. The synsets from WordNet are applied to extract semantic relations between concepts and their synonyms from the text corpus.

    (Lviv Politechnic Publishing House, 2019-04-18) Manuilov, Illia; Petrasova, Svitlana; National Technical University "Kharkiv Polytechnic Institute"
    The paper discusses the process of automatic extraction of paraphrases used in rewriting. The researchers propose the method for extracting paraphrases from English news text corpora. The method is based on both the developed syntactic rules to define phrases and synsets to identify synonymous words in the designed text corpus of BBC news. In order to implement the method, Natural Language Toolkit, Universal Dependencies parser and WordNet are used.
