To deal with this problem, we distinguish predicateargument examples, which are collected from a large corpus, by coupling a verb and its closest case component.
examples are not distinguished by verbs such as naru 'make/become' and tsumu 'load/accumulate', but by couples such as "tomodachi ni naru" 'make a friend', "byouki ni naru" 'become sick', "nimotsu wo tsumu" 'load baggage', and "keiken wo tsumu" 'accumulate experience'.
