"This is a prototype Contextual Thesaurus developed by Microsoft Research. Actually, it’s quite a bit more than that: it’s an English-to-English machine translation system that employs the same architecture that the Microsoft Translator uses when translating different languages. To the best of our knowledge, this is the first large-scale paraphrasing system anywhere." - FAQ from source
