Уточнение русскоязычных словарей эмоциональной лексики с использованием тезауруса RuThes (Refinement of Russian Sentiment Lexicons Using RuThes Thesaurus)

The paper describes a combined approach to extraction of a domain-specific sentiment lexicon. At first, an initial version of a domainspecific lexicon is obtained by application of a supervised model. At the second stage, the ordered list of sentiment words is refined using the thesaurus information. This combined model is applied to several domains and at last the domain-specific sentiment lexicons are united to create an improved version of the Russian sentiment lexicon in the generalized domain of products.
