... in both parsing and PP attachment tasks. We devise a gold-standard sense- and parse tree-annotated dataset based on the in- tersection of the Penn Treebank and SemCor, and experiment with different ... a full parsing and a PP attachment context. This paper shows that semantic classes achieve significant improvement both on full parsing and PP attachment tasks r...
