2. All comprehensible discourse (narratives, natural dialogues, etc.) is a structured entity which contains acoherent, and thereby interpretable structure of referential expressions. These traverse the text as anetwork of referential chains. Many entities (individuals, objects, abstract notions) referred to in a text arenewly introduced at some point and then taken up again, forming a referential chain.... While referentialchains describe a property of text structure, topics describe a property of common ground (CG)management and bring in the speaker/hearer perspective, which is particularly important todialogue. Adli, A.
