Word vector averaging has moreover proven surprisingly effective for learning relation vectors (Weston et al., 2013;Hashimoto et al., 2015;Fan et al., 2015; Espinosa Anke and Schockaert, 2018), as well as in related tasks such as sentence embedding (Wieting et al., 2016).
to construct the relation vector r wv capturing the relationship between the words w and v we proceed as follows.
