The DLA strategy we adopt in this research is based on supertagging, which is a simple instance of sequential tagging with a larger, more linguistically-diverse tag set than is conventionally the case, e.g., with part-of-speech tagging.
our particular interest in this paper is in the latter of these two, that is the development of methods for automatically expanding the lexical coverage of an existing precision grammar, or more broadly deep lexical acquisition (DLA hereafter).
