A central problem in work on the semantics/pragmatics interface, as well as in natural language processing is that of presupposition recognition, including the problem of anaphora resolution. Given recent evidence that the canonical presuppositions are anaphoric (Tonhauser et al., to appear), it is anaphora (e.g., as triggered by pronouns, demonstratives, and definite descriptions), and its cousins ellipsis and domain restriction, which give us the clearest evidence about how presupposition recognition works.
Interlocutors do a remarkably rapid job of correctly recognizing intended anaphoric presuppositions. But how do they do this? To say that it is a function of contextual salience only raises the question of what it is to be salient. It has long been recognized (Grosz 1977, Terken & Hirschberg 1994) that salience isn’t just a function of recency. I argue that to the extent that recency plays a role in salience, this is not directly a function of (e.g.) limits on short-term memory, but of attention. As the pervasive phenomenon of prosodic focus in natural language suggests, attention-direction plays a central, on-going role in processing and interpretation. And attention, I will argue, is both guided and constrained by intention-recognition. Specifically, in natural language discourse it is the intentional structure of discourse interactions which crucially guides attention, in turn facilitating presupposition recognition. Further, the evidence for dynamic interaction between pragmatically-mediated intention-recognition and conventionally-driven compositional semantics argues against the classical picture of interpretation, wherein semantics precedes pragmatic enrichment.
I bring to bear a variety of psychological and psycholinguistic evidence for this perspective, and consider briefly what it tells us about natural language processing and language acquisition. I also argue that it calls for a reconsideration of Kaplan’s view of the character and role of context in interpretation, a view which, in general form, remains quite influential in philosophy.
