Deep Serial Multi-Task Learning Model (SMTL). The purple part is the sequence of word embedding (seq) that represents the training citation. The pink part is the masking layer for unifying the length of each seq. The yellow part denotes the BGRU and the two directions of which are separated by a red line. The gray part is the output of the BGRU, which is the hidden state. The green part includes three fully connected layers and the rightmost one is the output layer of the primary classification. The blue part represents the structure of the SMTL, of which the rightmost one is the output layer of the auxiliary regression
