This study offers syntactic and semantic evidence that there are three types of locative modifiers within the verbal domain that differ with respect to their syntactic base position and interpretation. Two of them are subject to semantic indeterminacy, thereby leading to multiple utterance meanings. The study aims at showing that the full range of interpretations can be derived within a rigid account of lexical and compositional semantics. Locative modifiers are invariably treated as first-order predicates adding a locative constraint. All semantic (...) differences originate from the structural environment they are embedded in and the pragmatic resolution of semantic indeterminacy. The syntactic distribution of locative modifiers is shown to be derivable from interface conditions. (shrink)

This article offers a survey of computational research on referring expressions generation (REG). It introduces the REG problem and describes early work in this area, discussing what basic assumptions lie behind it, and showing how its remit has widened in recent years. We discuss computational frameworks underlying REG, and demonstrate a recent trend that seeks to link up REG algorithms with well-established Knowledge Representation traditions. Considerable attention is given to recent efforts at evaluating REG algorithms and the lessons that they (...) allow us to learn. The article concludes with a discussion of the way forward in REG, focussing on references in larger and more realistic settings. (shrink)
