<cite>Reddy et al. (2011)</cite> carried out experiments with a vector space model built from ukWaC (Ferraresi et al., 2008) using untyped co-occurrences (window size=100). Used 3-fold cross-validation, <cite>they</cite> found that using weighted addition outperformed multiplication as a compositionality function. With <cite>their</cite> optimal settings, <cite>they</cite> achieved a Spearman's rank correlation coefficient of 0.714 with the human judgments, which remains the state-of-the-art on this dataset 1 .
