Research Abstract

It is well known that, in addition to truth-conditional meanings, dialogues give rise to secondary meaning known as presupposition which is derived from sentences contained in the dialogue. Presuppositions constitute a condition for a sentence to be assigned a truth value. For example, the sentence, "Taro regrets that he has studied cognitive science," is assigned a truth-value only because it presupposes that Taro has studied cognitive science. It cannot be always assumed that presuppositions are explicitly expressed by previous sentences in the dialogue, and therefore, it is necessary to calculate presupposed meanings based upon the preceding dialogue. Furthermore, presuppositions are realized, i.e. projected, in more than one way. In this research :
(1)To isolate the way presuppositions are projected from preceding sentences, linguistic data have been collected and analyzed.
(2)Based upon the data, the inference process to calculate the projected presuppositions has been formalized. The formalization is cast in the framework of Satisfaction Theory and Anaphoric Resolution, and the predictions made by the model has been evaluated.
(3)The projection model has been embedded in a computer system for natural language processing, as part of its context analyzer.
