An algorithm was implemented for automatically generating tree-like discourse structures. This was used to generate a variety of discourse trees by using diierent attachment rules. The information used by these rules was essentially referential, and included continuity of theme, temporal reference, and pronominalisation in general. The trees in turn formed(More)
Computational approaches to reference resolution, like Centering Theory, are best at resolving referring expressions which denote familiar referents. We demonstrate how, by taking a proof-theoretic approach to reference resolution within a Centering-type framework, we are able to make sense of referring expressions for unfamiliar referents. These include,(More)
The problem of the acquisition of morpho-syntactic rules, as addressed by a number of existing computational models, is introduced. A distinction is made between ‘innatist’ models which presuppose the importance of innate linguistic knowledge (specifically, syntactic categories and X-Bar Theory), and ‘empiricist’ models, which reject such assumptions. It is(More)
arc also 'out of position', since you would normally expect VP-modi(ying PPs of this kind to appear immediately to the right of the modified VP (so that the canonical versions of these sentences would have been '1 met Ar thur in the park' and 'I believed that site loved me with all my heart. ') . There arc various reasons for moving things around in this(More)
Computer technology is increasingly bringing information which was previously the preserve of experts into people’s homes. We address the question of whether Artificial Intelligence can make accessible, to ordinary individuals, expert help in ethical decision-making. We propose an Ethical Decision Assistant and raise some important issues its design needs(More)
An account is ooered of the sense of referring expressions in in-tensional contexts. Unlike Russell's classic account in terms of the de re/de dicto distinction, this doesn't rely on a quantiier scope ambiguity in the logical form. Instead, diierent senses of a referring expression are captured by the diierent discourse models which emerge in diier-ent(More)
The notion of reference as entailment in the common ground provides a uniied framework for the treatment of denotation by names, deenite descriptions, and pronouns, including anaphors. Within this framework, semantic and pragmatic considerations are combined, giving two kinds of proof of denotation, by sense and by reference, for references to individuals(More)
An account of discourse connectives is given which focusses on their entailments. It covers uses of such connectives both to express discourse-internal situational relations and to express meta-level discourse relations. Representing the second of these involves explicitly introducing utterance mood into the logical form. The entailments of both situational(More)
