Outline of Final Research Achievements

The purpose of this research is to extend the conventional version of the Hachidaishu thesaurus (ca.905-1205) to include the Nijuichidaishu (ca.905-1429). At the same time, through its development, we attempt to develop a theory of the term space analysis (vocabulary system change) encompassing 534 years of ancient words based on classical Japanese poetry. Thesaurus data input was completed for all of the Nijuichidaishu, and the thesaurus code system and its vocabulary index system were completed. As a result of checking whether the description of the word in the thesaurus system is unified or not, we found that the system of the thesaurus itself is consistent with modern language. However, there exist contradictions when utilizing the distance calculation between ancient words.
