The increasing evidence that language processing is sensitive to lexical and structural co-occurrences at different levels of granularity and abstraction (Jurafsky, Bell, Gregory, & Raymond, 2001; Bybee, 2006) has led to the hypothesis that lexical and structural processing may be unified (MacDonald, Pearlmutter, & Seidenberg, 1994; Jurafsky, 1996). This paper examines the specific hypothesis t...

Chapman's hypothesis that contextual constraints are less salient and stronger meaning constraints more salient for schizophrenics than for normals was tested, as was the hypothesis drawn from the work of Salzinger and of Cromwell and Dokecki that schizophrenics are overly constrained by immediate cues relative to distant ones. The Chapman hypothesis was supported only for disorganized schizoph...

However, while the range of syntactic structures which might be assigned to these sentences is limited, it is by no means obvious what the correct structure is, or even if there is in fact just one. Be this as it may, we will assume here that the the double-object construction is subject to the same constraints as lexical argument structures in general. Using x to symbolize a lexical head, y a ...

To assign lexical stress when reading, the Greek reader can potentially rely on lexical information (knowledge of the word), visual–orthographic information (processing of the written diacritic), or a default metrical strategy (penultimate stress pattern). Previous studies with secondary education children have shown strong lexical effects on stress assignment and have provided evidence for a d...

This study aims to determine whether the production of the lexical variants created by the phonological processes of liaison and schwa deletion in French are conditioned by factors linked to lexical recognition. We hypothesise that the realisation of these variants would be favoured for words which are lexically “salient” in term of frequency and in their lexical neighbourhoods. This claim was ...

The PASCAL RTE challenge has helped LCC to explore the applicability of enhancements that have been made to our logic form representation and WordNet lexical chains generator. Our system transforms each T-H pair into logic form representation with semantic relations. The system automatically generates NLP axioms serving as linguistic rewriting rules and lexical chain axioms that connect concept...

Unknown lexical items present a major obstacle to the development of broadcoverage semantic role labeling systems. We address this problem with a semisupervised learning approach which acquires training instances for unseen verbs from an unlabeled corpus. Our method relies on the hypothesis that unknown lexical items will be structurally and semantically similar to known items for which annotat...

The investigation of language processing following brain damage may be used to constrain models of normal language processing. We review the literature on semantic and lexical processing deficits, focusing on issues of representation of semantic knowledge and the mechanisms of lexical access. The results broadly support a componential organization of lexical knowledge-the semantic component is ...

We present a prototype of the Italian version of WordNet, a general computational lexical resource. Some relevant extensions are discussed to make it usable for parsing: in particular we add verbal selec-tional restrictions to make lexical discrimination eeective. Italian Word-Net has been coupled with a parser and a number of experiments have been performed to individuate the methodology with ...
