Comparative analysis of nuclear energy vocabulary

The results of the analysis of terminological subsets of the characteristic vocabulary used for semantic identification of scientific and technical information in the field of fast reactors and light water reactors are discussed. The procedure of automatic formation of thematic dictionaries is considered. The dictionaries were formed through the processing of full-text materials such as dissertations and manuals on operation of nuclear reactors. The characteristic terms (in the form of phrases) are singled out from full texts by the methods of the statistic-linguistic analysis. The IAEA-INIS thesaurus is used. (author)
