Algorithms for NLG NLG is typically broken down into stages of discourse planning (to select information and organize it into coherent paragraphs), sentence planning (to choose words and structures to fit information into sentence-sized units), and realization (to determine surface form of output, including word order, morphology and final formatting or intonation). The SPUD system combines the generation steps of sentence planning and surface realization by using a lexicalized grammar to construct the syntax and semantics of a sentence simultaneously.

I argue for an account of vagueness according to which the root of vagueness lies not in the type of semantic-value that is best associated with an expression, but in the type of linguistic practice that renders the expression meaningful. I suggest, in particular, that conventions about how to use sentences involving attributions of vague predicates to borderline cases prevail to a lesser degree than conventions about how to use sentences involving attributions of vague predicates to clear cases.

way on the information available in the contexts in which they are used, it’s not surprising that there is a minor but growing industry of work in semantics and the philosophy of language concerned with the precise nature of the context-dependency of epistemically modalized sentences. Take, for instance, an epistemic might-claim like..

In this paper, we report results from experiments in which people read conversational arguments and then judge the convincingness of each claim and the individual speakers' burden of proof. The results showed an "anti-primacy" effect: People judge the speaker who makes the first claim as having greater burden of proof. This effect persists even when each speaker's claims are rated equally convincing. We also find that people rate claims less convincing when they appear in the first part of an argument (...) than when they appear in isolation. (shrink)

An essential ingredient of language use is our ability to reason about utterances as intentional actions. Linguistic representations are the natural substrate for such reasoning, and models from computational semantics can often be seen as providing an infrastructure to carry out such inferences from rich and accurate grammatical descriptions. Exploring such inferences offers a productive pragmatic perspective on problems of interpretation, and promises to leverage semantic representations in more flexible and more general tools that compute with meaning.

We relate the theory of presupposition accommodation to a computational framework for reasoning in conversation. We understand presuppositions as private commitments the speaker makes in using an utterance but expects the listener to recognize based on mutual information. On this understanding, the conversation can move forward not just through the positive effects of interlocutors’ utterances but also from the retrospective insight interlocutors gain about one anothers’ mental states from observing what they do. Our title, ENLIGHTENED UPDATE, highlights such cases. Our (...) approach fleshes out two key principles: that interpretation is a form of intention recognition; and that intentions are complex informational structures, which specify commitments to conditions and to outcomes as well as to actions. We present a formalization and implementation of these principles for a simple conversational agent, and draw on this case study to argue that pragmatic reasoning is holistic in character, continuous with common-sense reasoning about collaborative activities, and most effectively characterized by associating specific, reliable interpretive constraints directly with grammatical forms. In showing how to make such claims precise and to develop theories that respect them, we illustrate the general place of computation in the cognitive science of language. (shrink)

Both formal semantics and cognitive semantics are the source of important insights about language. By developing precise statements of the rules of meaning in fragmentary, abstract languages, formalists have been able to offer perspicuous accounts of how we might come to know such rules and use them to communicate with others. Conversely, by charting the overall landscape of interpretations, cognitivists have documented how closely interpretations draw on the commonsense knowledge that lets us make our way in the world. There is (...) no opposition between these insights. Sooner or later we will have a semantics that responds to both. However, developing such a semantics is profoundly difficult, because there are certain tensions to be overcome in reconciling the two perspectives. For one thing, the overall landscape of meaning does seem to be characterized by a much richer ontology and more dynamic categories than are exhibited by the fragments typically studied in the formal tradition. One sign of strain is the recent tendency to talk of “procedural”, “non-compositional”, or “computational” semantics, as in Hamm, Kamp and van Lambalgen 2006, hereafter HK&vL. We think such locutions can serve as useful reminders to keep semantics fixed on the central question of how language allows us to share information that some have and others need to get. However, there is some danger that formalists will merely by put off by an idea that, taken literally, may not be such a good one. In this short article, we want to explore and defend the traditional realist view attributed by HK&vL to Lewis among others. In fact, this view offers a well-developed, extremely straightforward and robust account of the relation between semantics and cognition. Moreover, while the realist view has ways of accommodating the representationalist insights of DRT (Lewis 1979; Thomason 1990; Stalnaker 1998), it remains unclear how “computational” semantics can account for the key data for the realist view: cases where we judge interlocutors to be ignorant about aspects of meaning in their native language (Kripke 1972; Putnam 1975; Stalnaker 1979; Williamson 1994)..

People care very much about being listened to. In everyday talk, we make moral-sounding judgements of people as listeners: praising a doctor who listens well even if she does not have a ready solution, or blaming a boss who does not listen even if the employee manages to get her situation addressed. In this sense, listening is a normative behaviour: that is, we ought to be good listeners. Whilst several disciplines have addressed the normative importance of interpersonal listening—particularly in sociology, (...) psychology, media and culture studies—analytic philosophy does not have a framework for dealing with listening as a normative interpersonal behaviour. Listening usually gets reduced mere speech-parsing, or into a matter of belief and trust in the testimony of credible knowers. My preliminary task is to analyse why this reductive view is taken for granted in the discipline; to diagnose the problem behind the reduction and propose a more useful alternative approach. The central task of my work is to give an account of listening which captures its distinctively normative quality as an interpersonal way of relating to someone: one listens not because the speaker is an epistemic expert, but because the speaker is a person, worthy of recognition and care. I created a framework which accomplishes this by deploying the conceptual resources of conversation sociology and psycholinguistics, in counterpoint to the standing philosophical work on the ethics and politics of speech and silencing, to create a practical ethics of listening to people.

I propose a new theory of semantic presupposition, which I call dissatisfaction theory. I first briefly review a cluster of problems − known collectively as the proviso problem − for most extant theories of presupposition, arguing that the main pragmatic response to them faces a serious challenge. I avoid these problems by adopting two changes in perspective on presupposition. First, I propose a theory of projection according to which presuppositions project unless they are locally entailed. Second, I reject the standard (...) assumption that presuppositions are contents which must be entailed by the input context; instead, I propose that presuppositions are contents which are marked as backgrounded. I show that, together, these commitments allow us to avoid the proviso problem altogether, and generally make plausible predictions about presupposition projection out of connectives and attitude predicates. I close by sketching a two-dimensional implementation of my theory which allows us to make further welcome predictions about attitude predicates and quantifiers. (shrink)

Lewis 1973 observed that his logic for counterfactuals could be applied to definite descriptions. His generalization was that the latter display the same non-monotonic patterns as the former, contrary to what Russellian or Strawsonian accounts would predict. We take Lewis's suggestion literally and suggest that ‘if' should be analyzed as the word ‘the' applied to a description of possible worlds. We do not follow Lewis's own implementation, however, for it entails that definite descriptions do not refer. Rather, we use von (...) Heusinger's Choice Function theory of definiteness to analyze both ‘if p' and ‘the P' as referential terms: ‘if p' denotes the closest p-world, while ‘the P' denotes the most salient P-individual.

This essay criticizes some strategies of Hegel scholarship, especially the non-metaphysical school and its recent metaphysical successor. My main claim is that these approaches are rhetorically opaque, and thus vulnerable to a certain anticolonial argument. In place of these strategies, I recommend and illustrate a more historically perspicuous approach that is sensitive to concerns about the role of European philosophy in the Americas.

A historical overview, with an attempt to rebut Grice's argument against Contextualism.

This paper develops an idea of saving ordinary uses of vague predicates from the Sorites by means of domain restriction. A tolerance level for a predicate, along a dimension, is a difference with respect to which the predicate is semantically insensitive. A central gap for the predicate+dimension in a domain is a segment of an associated scale, larger than this difference, where no object in the domain has a measure, and such that the extension of the predicate has measures on (...) one side of the gap and the anti-extension on the other. The domain restriction imposes a central gap. (shrink)

Process reliabilism says that a belief is justified iff the belief-forming process that produced it is sufficiently reliable. But any token belief-forming process is an instance of a number of different belief-forming process types. The problem of specifying the relevant type is known as the ‘generality problem’ for process reliabilism. This paper proposes a broadly relativist solution to the generality problem. The thought is that the relevant belief-forming process type is relative to the context. While the basic idea behind the (...) solution is from Mark Heller (1995), the solution defended here departs from Heller on a crucial point. Because of this departure, my solution avoids a serious problem with Heller’s solution. (shrink)

It is argued there is nothing special or deviant about the use of 'now' to refer to a time in the past (or about the use of 'here' to refer to a distant place) — no need to appeal to pragmatic mechanisms such as context-shifting to account for such uses. Such uses are puzzling only if one (mistakenly) maintains that 'here' and 'now' are pure indexicals. In the paper it is claimed that they are more similar to demonstratives than to (...) pure indexicals. Updated material on this can be found in *Truth-Conditional Pragmatics*, Chapter 6, 2010.

El principio de racionalidad, o de economía, puede expresarse como la hipótesis de que los sujetos tienden a llevar a cabo aquellas acciones que maximizan la diferencia entre beneficios y costes. Este principio es ampliamente aplicado en las ciencias sociales, sobre todo, obviamente, en la teoría económica, si bien en el último medio siglo ha sido aplicado también de manera creciente a otras ramas de dichas disciplinas (sociología, ciencia política, antropología, historia, etc.). En este artículo se discute la posibilidad de (...) aplicarlo a la lingüística y la pragmática, comentando varios de los trabajos realizados desde ese punto de vista, e ilustrándolos con su aplicación al caso del uso de expresiones vagas.
