We note that this measure is qualitatively similar to relational similarity model of (Turney, 2012), which predicts similarity between members of the word pairs To evaluate the vector offset method, we used vectors generated by the RNN toolkit of Mikolov (2012).
also of note, the use of distributed topic representations has been studied in (Hinton and Salakhutdinov, 2006;Hinton and Salakhutdinov, 2010), and (Bordes et al., 2012) presents a semantically driven method for obtaining word representations.
