“…In recent years, we witnessed the advance in neural network methodology, like fast training algorithm for deep multilayer neural networks (Chen, Liu, & Chiu, 2011;Ghiassi, Skinner, & Zimbra, 2013;Jian et al, 2010;Luong, Socher, & Manning, 2013;Moraes, Valiati, & Neto, 2013;Noferesti & Shamsfard, 2015;Sharma & Dey, 2012). Neural network techniques have found success in several NLP tasks recently such as opinion mining (Bobicev, Sokolova, Jafer, & Schramm, 2012;Socher, Lin, Manning, & Ng, 2011).…”
