Summary

This paper presents a higher-order dependency parser that can evaluate substructures containing three dependencies, using both sibling-style and grandchild-style interactions. The algorithms presented require only $O(n^{4})$ time and were evaluated on the Penn Treebank and the Prague Dependency Treebank. The implementation code was publicly released [1].

Dependency parsing is defined as a search for the highest-scoring analysis of x: $y^{*}(x)=_{y\in Y(x)}^{argmax}{\textrm {Score}}(x,y)$
