Table 4: Spearman’s correlation for HyperLex nouns for different negative sample schemes.

We note again that S1 is the technique used in literature Socher et al. and S2, S3, S4 are the new techniques we proposed. The notation, for instance, k×S1+S2 corresponds to using k samples from S1 and 1 sample from S2 per each positive sample. We observe that our new selection methods offer strong improvement from the range of 0.51−0.52 (using S1 alone) to 0.55 or above for most combinations with our new selection schemes.
