N2 - Many speech and language processing problems have been successfully cast as classification problems- associating a token with a label from a prespecified label set. However, in all these applications the set of labels is regarded as a flat list of symbols with no inherent internal structure and no co-constraints among the labels. In this paper, we present a classification task using structured word labels called Supertags and discuss methods that exploit the structure of these labels in the context of natural language generation. Supertags encode predicate-argument information along with syntactic ordering constraints that can be exploited for realizing a sentence. We report the accuracy of supertagging models for a node using features derived from its local tree context and attributes of the supertags.
