In order to compare ROOT9 to the state-of-the-art, we have evaluated it with the datasets created by<cite> Weeds et al. (2014)</cite> . The WN dataset<cite> (Weeds et al., 2014</cite> ) -meaning both WN Hyper and WN Co-Hyp -in particular, was built after noticing that supervised systems tended to perform well also on random vectors.
