Interesting, very optimistic project.. Put it just produces a mash of out of context snippets. The biggest problem is that it seems unable to identify introductory information very well, or eliminate references due to news items. I tried a couple of things:

http://cpedia.com/search?q=London%20Underground

Can anyone find something useful? I'd like to see a good article.
