This paper presents a higher-order model for constituent parsing aimed at utilizing more lo- cal structural context to decide the score of a grammar rule instance in a parse tree. Ex- periments on English and Chinese treebanks confirm its advantage over its first-order ver- sion. It achieves its best F1 scores of 91.86% and 85.58% on the two languages, respec- tively, and further pushes them to 92.80% and 85.60% via combination with other high- performance parsers.
