In this section, we calibrate the single prototype and multiprototype methods on WS-353, reaching the limit of human and oracle performance and demonstrating robust performance gains even with semantically impoverished features.
we obtain ρ0.75 correlation on WS-353 using only unigram collocations and ρ0.77 using a fixed-K multiprototype representation (Figure 3; Reisinger and Mooney, 2010).
