Clearly, a sufficiently large sense-tagged corpus is required for calculating the occurrence frequency of the individual senses of a word.
constructing a pseudoword by merely combining a random set of unambiguous words selected on the basis of their falling in the same range of occurrence frequency (Schütze, 1992), or leveraging homophones and OCR ambiguities (Yarowsky, 1993), does not provide a suitable model of a real polysemous word (Gaustad, 2001;Nakov and Hearst, 2003).
