In this paper, we have proposed novel methods for robust parsing that integrate the exibility of linguistically motivated lexical descriptions with the robustness of statistical techniques. Our thesis is that the computation of linguistic structure can be localized if lexical items are associated with rich descriptions (Supertags) that impose complex constraints in a local context. The supertag...

A cross-modal priming experiment was used to investigate lexical ambiguity resolution during sentence processing in individuals with nonthalamic subcortical lesions (NSL) (n = 10), compared to matched normal controls (n = 10), and individuals with cortical lesions (CL) (n = 10) and Parkinson's disease (PD) (n = 10). Critical sentences biased towards the dominant or subordinate meaning of a sent...

Levin’s (1993) study of verb classes is a widely used resource for lexical semantics. In her framework, some verbs, such as give, exhibit no class ambiguity. But other verbs, such as write, have several alternative classes. We extend Levin’s inventory to a simple statistical model of verb class ambiguity. Using this model we are able to generate preferences for ambiguous verbs without the use o...

In this paper, I will argue that the wellknown ambiguity of directional prepositions between the intrinsic and relative readings is not lexical, but can be interpreted as a framework assignment ambiguity of the type observed in the temporal domain. A DRT semantics will then be constructed around a unified model of framework assignment which can be applied across the board to all three universal...

The purpose of this chapter is to consolidate existing literature and introduce new evidence from both focal lesion and neurologically unimpaired populations which speak to the behavioral processes and neural substrates involved in lexical access and lexical ambiguity resolution during sentence comprehension. The chapter is dedicated to Edgar Zurif, and in many ways, writing it has brought each...

The aim of surface realisation is to produce a string from an input semantics. The task may be viewed as the inverse of parsing, and like parsing, it is made more difficult by the problem of lexical ambiguity in natural language. (Bonfante, Guillaume, and Perrier 2004) propose a polarisation technique for parsing that greatly reduces the effects of ambiguity. We show how polarisation can be ada...

Recent work on the nature of syntactic ambiguity has focused on the properties of lexical items that may be relevant to resolving such ambiguities. A variety of lexical properties have been proposed as having significant influence on syntactic ambiguity resolution. Ranging from referential properties (Ni, Crain, & Shankweiler 1996), in the context of the Referential Model of language processing...

The relation between lexical ambiguity and disambiguation ismostly approached from an intra-sentential perspective. Thus, when analyzing the ambiguity and disambiguation of a lexical item, one tends to study its variance in interpretation when it is modified by or occurs as an argument of other lexical items. Broadening this perspective, this paper shows that there are important insights into t...
