    <Paragraph position="0"> A discourse consists not simply of a linear sequence of utterances, 1 hut of meaningful relations among the utterances. As in much of the literature on discourse processing, we assume that certain spans of utterances, referred to here as discourse segments, form coherent units. The segmental structure of discourse has been claimed to constrain and be constrained by disparate phenomena: cue phrases (Hirschberg and Litman, 1993; Gross and Sidner, 1986; Reichman, 1985; Cohen, 1984); lexical cohesion (Morris and Hirst, 1991); plans and intentions (Carberry, 1990; Litman and Allen, 1990; Gross and Sidner, 1986); prosody (Grosz and Hirschberg, 1992; Hirschberg and Gross, 1992; Hirschberg and Pierrehumbert, 1986); reference (Webber, 1991; Gross and Sidner, 1986; Linde, 1979); and tense (Webber, 1988; Hwang and Schubert, 1992; Song and Cohen, 1991). However, there is weak consensus on the nature of segments and the criteria for recognizing or generating them in a natural language processing system. Until recently, little empirical work has been directed at establishing obje'~ively verifiable segment boundaries, even though this is a precondition for</Paragraph>
