Abstract
An essential step in understanding connected discourse is the ability to link the meanings of successive sentences together. Given a growing database to which new sentence meanings must be linked, which out of many possible inference chains will succeed? To which items already in a data base is a new item relevent? To assure easy understandability of text the amount of processing time spent on unsuccessful linkage attempts must be reduced. This paper develops a preliminary theory of discourse structure. Several newspaper articles were examined in the light of this theory. Two examples were worked out in detail to explore how a hypothetical discourse understander might use the model of discourse structure to represent knowledge gained from processing text.
