Word similarity datasets have been one of the oldest, still most prominent, benchmarks for the evaluation and comparison of semantic representation techniques.
several word similarity datasets have been constructed during the past few decades; to name a few: RG-65 (Rubenstein and Goodenough, 1965), WordSim-353 (Finkelstein et al., 2002), YP-130 (Yang and Powers, 2005), MEN-3K (Bruni et al., 2014), SimLex-999 (Hill et al., 2015), and SimVerb-3500 (Gerz et al., 2016).
