Establishment of Categories of Synonymous Relation through Semantic Similarity Analysis

The purpose of this paper is to establish the type of synonymous relation vocabulary by analyzing the semantic similarity. Until now, the definition of synonym has been presented in various ways by scholars, and various approaches exist in analyzing the type accordingly. It is not easy to discriminate actual significance. The reason is that the similarities between vocabulary appear very diverse, and the range of synonyms varies greatly depending on which of these similarities is admitted to be the same. In this paper, in order to determine the degree of similarity of vocabulary in a synonymous relation and to suggest a type classification plan accordingly, a similarity survey will be conducted for native Korean speakers. By analyzing and comparing the colloquial corpus along with the similarity score, looking at the aspects of the synonymous relation vocabulary used with the recognized synonymous relation vocabulary, it will provide an opportunity to establish a hierarchy of synonymous relation vocabulary that has not been organized so far.
