Procedures and Problems in Korean-Chinese-Japanese Wordnet with Shared Semantic Hierarchy

This paper introduces a Korean-Chinese-Japanese wordnet for nouns, verbs and adjectives. This wordnet is constructed based on a hierarchy of shared semantic categories originated from NTT Goidaikei (Hierarchical Lexical System). The Korean wordnet has been constructed by mapping a semantic category to each Korean word sense in a way that maps the same semantic hierarchy to the meanings of nouns, verbs, and adjectives. The meaning of each verb searched in the corpus is compared with its Japanese equivalent. The Chinese wordnet has been also constructed based on the same semantic hierarchy in comparison with the Korean wordnet. In terms of the argument structure, there is a semantic correspondence between Korean, Japanese and Chinese verbs.
