For examples, Kawahara and Kurohashi proposed a method for constructing wide-coverage case frames from large corpora (Kawahara and Kurohashi, 2006b), and a model for syntactic and case structure analysis of Japanese that based upon case frames (Kawahara and Kurohashi, 2006a).
they did not demonstrate whether the coverage of case frames was wide enough for these tasks and how dependent the performance of the model was on the corpus size for case frame construction.
