XTAG meeting on April 27, 10:30am

Tonia and Fei will be talking about non-local dependencies in the
Penn treebank. Their abstract:

We will present Fei's algorithm for finding examples of non-local
dependencies in the Penn Treebank. Based on the data found by the
algorithm, we present a case study of Extraposition from NP. The
dependency involved in extraposition of adjunct phrases is non-local, and
would require a non-local MCTAG if we were to model the dependency as a
syntactic one. We show, however, that the dependency involved is a
semantic one rather than a syntactic one, and hence does not require
non-local MCTAG.
