According to the alternative semantics for focus, the semantic reflec of intonational focus is a second semantic value, which in the case of a sentence is a set of propositions. We examine a range of semantic and pragmatic applications of the theory, and extract a unitary principle specifying how the focus semantic value interacts with semantic and pragmatic processes. A strong version of the theory has the effect of making lexical or construction-specific stipulation of a focus-related effect in association-with-focus constructions (...) impossible. Furthermore, while focus has a uniform import, the sources of meaning differences in association with focus are various. (shrink)

In this book, two related phenomena are studied: presupposition and anaphora. Dynamic semantics is by now widely accepted as a first-rate foundation for such an exercise and it forms the backbone of most of the work in this book. A recurring additional theme of the present book is the usefulness of techniques from partial logic in the treatment of both phenomena. Rather than adding completely new semantic theories to the present gamut of theories, the author discusses a number of existing (...) approaches which aim at accounting for the behavior of presuppositions and/or anaphors, makes improvements where necessary, and compares the results. Presupposition and Anaphora starts with an introduction to a number of dynamic semantic theories and their correlations, paying special attention to the treatment of disjunctions and negations. Subsequently, presuppositions are studied in the context of partial logics, Montague Grammar and dynamic semantics. (shrink)

It is routinely observed in NLP that sentences seem to “evoke” situations (where I use this term comprehensively to cover events, episodes, eventualities, processes, etc.). Much like discourse entities evoked by explicit noun phrases, these evoked situations can be referred to anaphorically, as for instance in (1) and (3) below, and can be modified in various ways, for instance by supplying their duration and location, as in (2) and (4).
