“…Since distributed representations play an important role in various NLP tasks, they are applied to semantics (Herbelot and Vecchi, 2015;Qiu et al, 2015;Woodsend and Lapata, 2015), with incorporating external information to them (Tian et al, 2016;Nguyen et al, 2016). In addition, finding interpretable regularities from the representations is often conducted through non-negative and sparse coding (Murphy et al, 2012;Faruqui et al, 2015;Luo et al, 2015;Kober et al, 2016), and regularization (Sun et al, 2016).…”
