The feature set of our model is fundamentally a combination of the features used in the state-of-the-art joint segmentation and POS tagging model (Zhang and Clark, 2010) and dependency parser (Huang and Sagae, 2010), both of which are used as baseline models in our experiment.
we must carefully adjust which features are to be activated and when, and how they are combined with which action labels, depending on the type of the features because we intend to perform three tasks in a single incremental framework.
