We col- lect predicate-argument examples, which are distinguished by the verb and its closest case component in order to deal with verb usages, from parsed results of a corpus. Since these couples multiplyto millionsofcombinations, it isdif- ficult tomakeawide-coverage case framedictionaryfroma small corpus like an analyzed corpus. We, however, use a rawcorpus,sothatthisproblemcanbeaddressed. Further- more, we cluster and merge predicate-argument examples whichdoes nothave different usages but belong todifferent case frames because of different closest case components. We also report on an experimental result of case structure ana...
