Ellipsis in Computational Linguistics

This chapter considers approaches to ellipsis within computational linguistics. It begins with the structure of the ellipsis site - a topic that has received little attention in computational linguistics. There are two prominent accounts of the recovery of ellipsis: that of Lappin and McCord (1990) and Dalrymple et al. (1991). The topic of licensing follows. This topic has not been directly addressed in the computational literature, but the chapter covers two related issues of direct computational interest: the identification and generation of ellipsis occurrences. This is followed by three additional topics: identifying the antecedent, dialogue, and text mining.
