First, we tested the ability to capture syntactic similarity of each model by checking whether the POS of each word was the same as the POS of a neighboring word in the vector space.
we calculated SYNTAXACC@N defined as follows: where I[condition] = 1 if the condition is true and I[conditon] = 0 otherwise, the function POS(w) returns the actual POS tag of the word w, and N (w) denotes the set of the N top similar words {w } to w w.r.t.
