In this paper we compare two types of corpus, focusing on the lexical mnbiguity of each of them. The first corpns consists mainly of newspaper articles and Hterature excerpts, while the second belc)ngs to the medical domain. To conduct the study, we have used two different disambiguation tools. However, first of all, we must verify the performance of each system in its respective application do...

From a certain (admittedly narrow) perspective, one of the annoying features of natural language is the ubiquitous syntactic ambiguity. For a computational model intended to assign syntactic descriptions to natural language text, this seem like a design defect. In general, when context and lexical content are taken into account, such syntactic ambiguity can be resolved: sentences used in contex...

Terminology systems that represent the language as used in human communication have to deal with the problem of lexical ambiguity; i.e. the same natural language term is assigned to two or more codes. A scrutiny of the large international terminology standard SNOMED CT focused on concepts that are linked by the same term and exhibit problems especially when using the terminology in a Natural La...

An event-related fMRI paradigm was used to investigate brain activity during the reading of sentences containing either a lexically ambiguous word or an unambiguous control word. Higher levels of activation occurred during the reading of sentences containing a lexical ambiguity. Furthermore, the activated cortical network differed, depending on: (1) whether the sentence contained a balanced (i....

Lexical ambiguity has been the focus for the study of context effects in word recognition in the past twenty-five years (Small, Cottrell, and Tanenhaus 1988, Onifer and Swinney 1981, Simpson and Krueger 1991, Swinney 1979, Tabossi 1988). Most of this literature has been concerned with the study of Indo-European languages, in particular, English. However, the phenomenon of lexical ambiguity is p...

This paper reports the results of a lexical decision experiment and a selfpaced reading experiment that investigate the interaction between syntactic and lexical information in on-line language processing, using the noun-verb ambiguity in English. The results of both experiments provide support for the hypothesis whereby syntactic and lexical information are two independent factors in the proce...

Models of lexical ambiguity resolution differ mainly with respect to the role played by context in lexical access. In my paper I focus on two opposing views: those of autonomous access models (non-context-oriented) and selective access models (context-oriented). I analyse two types of situations of: a. the activation of a wrong meaning of an ambiguous word unpredictable from both models and b. ...
