Probabilistic Shift-Reduce Parsing Model Using Rich Contextual Information
In this paper, we present a probabilistic shift-reduce parsing model which can overcome low context-sensitivity of previous LR parsing models. Since previous models are restricted by LR parsing framework, they...

A Semi-automatic Tree Annotating Workbench for Building a Korean Treebank
In this paper, we propose a semi-automatic tree annotating workbench for building a Korean treebank. Generally, building a treebank requires an enormous effort by the annotator. In order to improve annotating ...
