This paper examines the case for a graded notion of word meaning in twoexperiments, onewhichusesWordNet senses in a graded fashion, contrasted with the “winner takes all” annotation, and one whichasks annotatorsto judgethe similar- ity of two usages. We find that the graded responses correlate with annotations from previous datasets, but sense assignments are used in a way that weakens the case for clear cut sense boundaries. The responses from both experiments correlate with the overlap of paraphrases from the English lexical substitution task which bodes well for the use of substitutes as a proxy for word sens...
