[Corpora-List] Ask for Paraphrase test corpus!

[Jun Lang]

Dear all members,
	 My research is on question paraphrasing, which aims to generate all 
the paraphrases of given questions. Now I want to collect test data for 
evaluation. The data should contain groups of question sentences and 
sentences in the same group can be regarded as paraphrases. So if you are a 
researcher on paraphrasing and have such a corpus, would you please share it 
with me. If you can help me, I'd really appreciate it. 

Best Wishes!
