For overcoming these issues, relational similarity was combined with lexical similarity calculated based on the distributional information of words (Cederberg and Widdows, 2003;Snow et al., 2004;Turney, 2006a;Séaghdha and Copestake, 2009;Herdadelen and Baroni, 2009).
(Turney, 2006b;Turney, 2008a) showed that relational similarity cannot be improved using the distributional similarity of words.
