| Abstract |
In this paper, we present a tool that allows one to automatically extract verb argument-structure from the Penn Treebank as well as from other corpora annotated with the Penn Treebank release 2 conventions. More specifically, we examine each possible sequence of tags, both functional and categorial and determine whether such a sequence indicates an obligatory argument, an optional argument or a modifier. We argue that this approach is more fine-grained and thus more satisfactory than the existing approaches which have aimed at determining argumenthood in the Penn Treebank. The goal of this work is to provide a set of sufficiently general and fine-grained rules as well as an implementation which will be reusable and freely available to the research community. |
