Olga,
We have developed an automated system called SHARES (System of Hypermatrix Analysis, Retrieval, Evaluation and Summarisation) that clusters related documents in a general news corpus and ranks them in order of similarity, by a method developed out of past work, including lexical cohesion. SHARES identifies topic at a series of levels, and is more linguistically refined in its approach than some other systems. There is a small demo online at www.rdues.uce.ac.uk/sharesguide/ and a user guide. Such clustering techniques can be used on a pair of general corpora from different sources to extract the kind of sets you are interested in.
Yours
Jay

Subject: [Corpora-List] English-language paraphrase corpora
Dear All,
I am looking for English-language "comparable" corpora. I.e. I want,
e.g., 2 collections of articles from different sources describing same events.
Alternatively, would anyone know off-hand how one would go about
constructing such comparable collections?
(This is to be used for automatic paraphrasing.)
Any pointers greatly appreciated,
Olga
