Have you tried http://www.onelook.com/reverse-dictionary.shtml http://www.onelook.com/reverse-dictionary.shtml? Edit: There is also : http://wordgrabbag.com/ http://wordgrabbag.com/ - which seems to do this better, but I'd probably use a combination of those. Edit: Just remembered that this tutorial loads all of the word2vec data (and at the bottom) allows API access into it for similar words. http://rare-technologies.com/word2vec-tutorial/ http://rare-technologies.com/word2vec-tutorial/
