Sustained meaning activation for polysemous but not homonymous words: evidence from EEG.
Theoretical linguistic accounts of lexical ambiguity distinguish between homonymy, where words that share a lexical form have unrelated meanings, and polysemy, where the meanings are related. The present study explored the psychological reality of this theoretical assumption by asking whether there is evidence that homonyms and polysemes are represented and processed differently in the brain. W...
متن کاملValency Frames of Polysemous and Homonymous Verbs in VerbaLex
Verb valency lexicon VerbaLex is one of few language resources which take a local context into account. For each Czech verb with its sense, VerbaLex contains appropriate valency frames (patterns with morphological and syntactical information) in which the verb can appear. This, and the fact that a context of a word is crucial for determining sense of the word, makes VerbaLex suitable for disamb...

متن کاملUnsupervised Learning of Visual Sense Models for Polysemous Words
Polysemy is a problem for methods that exploit image search engines to build object category models. Existing unsupervised approaches do not take word sense into consideration. We propose a new method that uses a dictionary to learn models of visual word sense from a large collection of unlabeled web data. The use of LDA to discover a latent sense space makes the model robust despite the very l...
متن کاملNot all ambiguous words are created equal: an EEG investigation of homonymy and polysemy.
Event-related potentials (ERPs) were used to investigate the time-course of meaning activation of different types of ambiguous words. Unbalanced homonymous ("pen"), balanced homonymous ("panel"), metaphorically polysemous ("lip"), and metonymically polysemous words ("rabbit") were used in a visual single-word priming delayed lexical decision task. The theoretical distinction between homonymy an...
