[Corpora-List] Help Needed

[Nitin Madnani]

I forgot to mention that if you are interested in examples of
sentential paraphrases that people have generated as part of their
research, there are some good datasets available:

(1) http://www.cs.cornell.edu/Info/Projects/NLP/statpar.html

(2) http://research.microsoft.com/en-us/downloads/607d14d9-20cd-47e3-85bc-a2f65cd28042/

Cheers,
Nitin
