In contrast, we are concerned with a very large dataset of templates extracted from a single corpus, where any two templates are potential paraphrases.
paraphrasal templates can be extracted from sentences which are not in fact paraphrases; for example, the sentences "The population of Missouri includes more than 1 million African Americans" and "Roughly 185,000 Japanese Americans reside in Hawaii" can produce the templated paraphrases "The population of [american state] includes more than [number] [ethnic group]" and "Roughly [number] [ethnic group] reside in [american state]".
