Impairments of semantic processing and inhibition have been observed in Parkinson's disease (PD), however, the consequences of faulty meaning selection and suppression have not been considered in terms of subsequent lexical processing. The present study employed a lexical ambiguity repetition paradigm where the first presentation of an ambiguity paired with a target biasing its dominant or subo...

This paper proposes lexical annotation as an effective method to solve the ambiguity problems that affect ontology matchers. Lexical annotation associates to each ontology element a set of meanings belonging to a semantic resource. Performing lexical annotation on the ontologies involved in the matching process allows to detect false positive mappings and to enrich matching results by adding ne...

Lexical information is one of the most important source that can improve the accuracy of the syntactic disambigua-tion. This paper describes a Korean probabilistic parser that is based on the probabilities of phrase structure rules as well as the probabilities of collocational information between lexical items to resolve syntactic ambiguity. The proposed parser is shown by means of an extensive...

Prior studies exploring the contribution of amplitude envelope information to spoken word recognition are mixed with regard to the question of whether amplitude envelope alone, without spectral detail, can aid isolated word recognition. Three experiments show that the amplitude envelope will aid word identification only if two conditions are met: (1) It is not the only information available to ...

The current study investigated ambiguity errors that characterise the L2 tertiary-level writing of Chinese college students. Data were drawn from 56 authentic English writings 11 students different disciplines across 10 institutions. A thematic analysis was conducted to examine error patterns at lexical and syntactic levels. Lexical ambiguities found include Chinglish, ambiguous references, abs...

Planning-based approaches to reference provide a uniform treatment of linguistic decisions, from content selection to lexical choice. In this paper, we show how the issues of lexical ambiguity, vagueness, unspecific descriptions, ellipsis, and the interaction of subsective modifiers can be expressed using a belief-state planner modified to support context-dependent actions. Because the number o...

The present work suggests that sentence processing requires both heuristic and algorithmic processing streams, where the heuristic processing strategy precedes the algorithmic phase. This conclusion is based on three self-paced reading experiments in which the processing of two-sentence discourses was investigated, where context sentences exhibited quantifier scope ambiguity. Experiment 1 demon...

Part of speech taggers based on Hidden Markov Models rely on a series of hypotheses which make certain errors inevitable. The idea developed in this paper consists in allowing a limited, controlled ambiguity in the output of the tagger in order to avoid a number of errors. The ambiguity takes the form of ambiguous tags which denote subsets of the tagset. These tags are used when the tagger hesi...
