- In this paper, I suggest a way of mapping the Mikrokosmos Ontology being developed at CRL (Computing Research Lab) of New Mexico State University, into lexical items. Many extensions to the Korean lexical meaning classifications have largely relied on the noun classifications and conceptual considerations. Those approaches, however, have proven to be insufficient in the case of Korean because lexical meaning classifications hardly fit in with conceptual structures. Along the same lines, simple meaning classification itself does not contribute to either theoretical linguistics or natural language processing. To resolve this problem, I introduce the language-independent conceptual structures, the Mikrokosmos ontology, which contain about 5,000 concepts encapsulating various lexical information in a frame. And I show how to map each individual sense of a word into the corresponding conceptual structure. Adopting this approach to Korean is an even greater challenge because Korean is such a polysemous complicated language. The ontology-based conceptual structure and its mapping to the lexical items allow us to disambiguate polysemous words and come up with unified ways of lexicon building.
