... edge in the depen- dency tree. The score of an edge is in turn com- puted as the inner product of a high-dimensional feature representation of the edge with a corre- sponding weight vector, s(i, ... j), which is the score of creating a pair of adjacent edges, from word x i to words x k and x j . For instance, s(2, 4, 5) is the score of creating the edges from hit to with and f...
