Qualitative versus Quantitative Notions of Speaker and Hearer Belief: Implementation and Theoretical Extensions

Yafa Al-Raheb

This paper investigates the notion of the Stalnakerean acceptance in relation to common ground, exploring alternative contexts where the Stalnakerean view of acceptance is insufficient (2002). Thus, this paper extends the Stalnakerean notion of acceptance through the introduction of qualitative as well as quantitative notions of beliefs into Discourse Representation Theory (DRT), corresponding to a weaker degree of belief than contexts requiring a stronger commitment beliefwise on the hearer’s part. In addition, emphasis is placed on viewing presuppositions through agents’ beliefs instead of the vague notion of common ground. These qualitative and quantitative notions of beliefs are then implemented as part of a speaker/ hearer model of dialogue.
