Frank Wiles' News Cloud is a tag cloud interface to washingtonpost.com news stories. It automatically pulls keywords out of stories and presents a way of navigating the news by keyword. Frank made it for fun, as an experiment.
Here's how it works, direct from the about page:
NewsCloud is an application that takes all of the RSS feeds from the Washington Post website and builds a blog like tag cloud from the keywords. Each story's full text is pulled from the website and indexed by [these] keywords. There are typically around 11,000 news stories and 60,000 keywords being indexed at any given time.
Not only is it an interesting way of browsing news; it also comes in handy for finding other stories on a similar topic. Nice work, Frank!
