In this work we learn clusters of contex- tual annotations for non-terminals in the Penn Treebank. Perhaps the best way to think about this problem is to contrast our work with that of Klein and Man- ning (2003). That research used tree- transformations to create various gram- mars with different contextual annotations on the non-terminals. These grammars were then used in conjunction with a CKY parser. The authors explored the space of different annotation combinations by hand. Here we try to automate the process — to learn the “right” combination auto- matically.
