State-of-the-art graph-based dependency parsers use features over higher-order dependencies that rely on decoding algorithms that are slow and hyper-specialized. In contrast, transition-based dependency parsers can easily utilize such features without an increase in asymptotic complexity. To address this imbalance, we generalize the Eisner algorithm to handle arbitrary features by enriching chart signatures without changing the underlying dynamic programming algorithm. While this generaliz
