Here's another article on IBM's Web Fountain: " The result is a new online service called WebFountain. A big computer at IBM hoovers up web pages and information from other sources such as newsgroups, syndicated content and newswires. Each incoming page is analysed to determine what language it is in. The context—a news report, a page on a company's website, a web-log entry—is determined. Verbs, nouns, adjectives, proper nouns, place names and even entire phrases are extracted, and are analysed for positive or negative connotations. The page is also classified by category—is it about baseball, Iranian politics or global warming?"
