In comparison, the advantage of the syntactic information is not at all obvious when they are used in a non-factorized fashion in the DEP model; it out-performs the window-based methods (below the dashed line) on only 3 datasets with limited margins.
the window-based methods consistently outperform the dependencybased methods on the FG dataset, confirming our intuition that window-based methods are better at capturing relatedness than similarity.
