This paper proposes a method of fertilizing a Japanese case frame dictionary to handle com- plicated expressions: double nominative sen- tences, non-gapping relation of relative clauses, and case change. Our method is divided into two stages. In the first stage, we parse a large corpus and construct a Japanese case frame dic- tionary automatically from the parse results. In the second stage, we apply case analysis to the large corpus utilizing the constructed case frame dictionary, and upgrade the case frame dictio- nary by incorporating newly acquired informa- tion.
