The quantification of lexical semantic relatedness has many applications in NLP, and many different measures have been proposed. We evaluate five of these measures, all of which use WordNet as their central resource, by comparing their performance in detecting and correcting real-word spelling errors.

In addition, we explain why distributional similarity is not an adequate proxy for lexical semantic relatedness.
