CoreNet: Chinese-Japanese-Korean wordnet with shared semantic hierarchy

A Chinese-Japanese-Korean wordnet is introduced. It is constructed based on a shared semantic hierarchy that is originated from NTT Goidaikei (Lexical Hierarchical System). Korean wordnet was constructed through the semantic category assignment to every sense of Korean words in a dictionary. Verbs and adjectives senses are assigned to the same semantic hierarchy as that of nouns. Each sense of verbs is investigated from corpora for their usage, and compared with Japanese translation. Chinese wordnet with the same semantic hierarchy was built up based on the comparison with Korean wordnet. Each sense of Chinese verb corresponds to Korean with its argument structure. These works have lasted since 1994.
