We have constructed a powerful parser of Japanese sentences. This parser can resolve ambigities of input sentences by utilizing various kinds of semantic relationships among words. Especially, the 'case' concept introduced by C.J. Fillmore plays an important role in this parser. Case is the relation which is established between an object and an event. In a sentence, an object is usually expressed by a moun phrase and an event by a verb. The information as to what kinds of cases should be described and what kinds of nouns should be selected as case-elements of a verb dictionary. A verb may have more that one case frames corresponding to defferent usages of the verb. A noun represents a set of objects which have certain same properties. We express properties by attribute-value pairs in the noun dictionary. The dictionary also contains the set-inclusion relationships among nouns. In this paper, we will explain how the parser utilizes these dictionaries in order to analyze a noun phrase and a simple sentence.
