As a type of Multiword Expression (Sag et atl., 2002; Baldwin & Bond, 2002), Japanese verbal compounds (V1-V2 compounds, hereafter) pose serious problems for Japanese Natural Language Processing (NLP) and require a sophisticated linguistic treatment. Hashimoto (2004) presented such a treatment of V1-V2 compounds based on the JACY framework (Siegel & Bender, 2002). However, the treatment suffered from overgeneration involving what Matsumoto (1996) calls `V1-V2 with semantically deverbalized V1', which is peculiar in that, even though it shows (partial) compositionality, its productivity is very restricted. In this paper, I propose an alternative analysis for V1-V2 with semantically deverbalized V1, where all V1-V2s of that kind are regarded as single words to account for their restricted productivity but are given (partially) compositional semantic representations. Also, I report on an evaluation experiment that shows an advantage of the alternative treatment. Finally, I argue that grammar developers should take into account computational parsimony; we should not try too hard to generalize phenomena that we can easily enumerate exhaustively.
