Most work on sense disambiguation presumes that one knows beforehand — e.g. from a thesaurus — a set of polysemous terms. But published lists invariably give only partial coverage. For example, the English word tan has several obvious senses, but one may overlook the abbreviation for tangent. In this paper, we present an algorithm for identifying interesting polysemous terms and measuring their...

The current project investigated the extent to which several lexical aspects of second language (L2) speech—appropriateness, fluency, variation, sophistication, abstractness, sense relations— interact to influence native speakers’ judgements of comprehensibility (ease of understanding) and accentedness (linguistic nativelikeness). Extemporaneous speech elicited from 40 French speakers of Englis...

Two challenging issues are notable in tweet clustering. Firstly, the sparse data problem is serious since no tweet can be longer than 140 characters. Secondly, synonymy and polysemy are rather common because users intend to present a unique meaning with a great number of manners in tweets. Enlightened by the recent research which indicates Wikipedia is promising in representing text, we exploit...

In this paper I evaluate extant lexical acquisition techniques for NLP systems with respect to the problem of polysemy. I argue that available lexical resources are inadequate for creating computational lexica capable of addressing the generativity of language use. I suggest several desiderata for lexical resources, to increase their utility for lexical acquisition in the context of polysemy: f...

We characterize the codominance pairspairs of posets that admit simultaneous dominance representations in the (x; y)-and (?x; y)-coordinate systemssand present a linear algorithm to recognize them and construct codomi-nance representations. We deene dominance polysemy as a generalization of codom-inance and describe several related problems and preliminary results. Ensembles partiellement ordon...

the case of Mandarin verb ZOU (走) Yaling Hsu Meichun Liu National Chiao Tung University [email protected] [email protected] Abstract In this paper, we propose a procedural schema as a model of cognitive processing of word senses, which can be viewed as a derivational resolution of polysemy. Previous researches, such as Frame -Based Lexicon by Fillmore [4] and Lexical Semantics by Crus...

What is ambiguity, and why does it matter in policy change? Often treated as an exogenous factor, the ambiguity of ideas has been considered a taken for granted entity instrumental to actors’ strategic action. Less attention devoted elucidating nature drivers process. Building on concept ‘boundary objects’, originally developed within sociology science, this article identifies polysemy one expl...
