The purpose of this paper is to solve the contextual ellipsis problem that is popular in our Chinese spoken dialogue system named EasyNav. A Theme Structure is proposed to describe the attentional state. Its dynamic generation feature makes it suitable to model the topic transition in user-initiative dialogues. By studying the differences and the similarities between the ellipsis and the anaphora phenomena, we extend the resolution procedure and the theory from anaphora to ellipsis. The ellipsis resolution is now based on the semantic knowledge and the discourse factor other than the syntactic information. A Theme Structure Method proposed in this paper for the ellipsis resolution is uniform to not only all kinds of elliptical elements but also some particular ellipsis types such as the fragmental ellipsis and the default ellipsis.
