Productivity of Predicative Nominal and Non-predicative Nominal Constructions

In this study, we investigate productivity of nominal and non-nominal constructions in Korean. According to Lee(2005), nominal predicative construction is more morphologically productive than non-predicative nominal construction. We use the productivity index proposed in Baayen (1991, 1992, 1993, 2001). The result reveals that the productivity hypothesis in Lee (2005) does not hold the validity. Unlike Lee (2005), productivity of predicative/non-predicative nominal constructions is based on the argument structure, inducing consideration on the syntax-semantics (and/or syntactic structures). In order to capture such structure notion, we propose the type-token ratio of morphological tag concatenates which reflect syntactic and/or syntax-semantic information. Also, we find out that our proposal of the type-token ratio is more effective in explaining distribution of productivity.
