In Japanese, case structure analysis is very im- t)ortant to handle several troublesome charac- teristics of Japanese snch as scrambling, onfis- sion of ease components, mid disappearance of case markers. However, fi)r lack of a wide- coverage ease frame dictionary, it has been dif- ficult to perfornl case structure analysis accu- rat;ely. Although several methods to construct a ease fl'mne dictionary from analyzed corpora have been proposed, they cannot avoid data sparseness 1)rol)lem. This paper proposes an un- supervised method of constructing a case frame dictionary from an enormous raw corpus by us- ing a robust and accurate parser. It also pro- rides a case structure analysis method based on the constructed dictionary.
