Multiword expressions are a key problem for the development of large-scale, linguistically sound natural language processing technology. This paper surveys the problem and some currently available analytic techniques. The various kinds of multiword expressions should be analyzed in distinct ways, including listing “words with spaces”, hierarchically(More)

In this paper, we present a unified feature-based theory of complement, adjunct, and subject extraction, in which there is no need either for valence reducing lexical rules or for phonologically null traces. Our analysis rests on the assumption that the mapping between argument structure and valence is defined by realization constraints which are satisfied(More)
Abstract This paper sketches a grammar of English relative clause constructions (including infinitival and reduced relatives) based on the notions of construction type and type constraints. Generalizations about dependency relations and clausal functions are factored into distinct dimensions contributing constraints to specific construction types in a(More)
We describe minimal recursion semantics (MRS), a framework for semantics within HPSG, which considerably simplifies transfer and generation. We discuss why, in general, a semantic representation with minimal structure is desirable for transfer and illustrate how a descriptively adequate representation with a non-recursive structure may be achieved. The(More)
The French clitic system has posed a persistent challenge to transformational syntactic analysis, which has never produced a successful account of problems such as clitic ordering. Lexicalist alternatives, however, have never been reconciled with the full range of familiar problems and the growing body of known lexical idiosyncracies. We present a(More)
Competence-based theories of island effects play a central role in generative grammar, yet the graded nature of many syntactic islands has never been properly accounted for. Categorical syntactic accounts of island effects have persisted in spite of a wealth of data suggesting that island effects are not categorical in nature and that non-structural(More)
1Above all, I’d like to thank Paul Kay for hours of discussion and useful feedback at every stage in the seemingly endless process of writing this chapter. I’m also grateful to Chuck Fillmore and Laura Michaelis for many useful discussions of both content and exposition and for comments on an earlier draft, which was also been improved by the comments of(More)
