Abstract (in Japanese) (See Japanese page) 
(in English) We have made a Japanese functional expression analizer using Japanese functional expression dictio-
nary \Tsutsuji." The implementation is, morphologically analyzed text is rst regarded as a list of morphemes,
and then, by looking up the entry of \Tsutsuji," the candidate of functional expressions are span as edge to form a
word lattice structure. By choosing the best path from the lattice, the disambiguations of the Japanese functiona
expressions are achieved. To decide an optimal path from the lattice, Markov model is used, and the Markov model
is trained from corpus. We applied the method to the corpus of opinions to the broadcasting company, and obtained
87.51(%) accuracy, which is comparable level to conventional method that uses SVM.
