Zemanta API is state of the art in text analysis.
For any input text you get entities, related images, articles, hyperlinks, and tags to use to your liking.
It's easy. Just three steps:
7th January 2011 -- We've added some new parameters to our responses. Among others you can find "relevance" for links (we used to do just "confidence") and "entity_type" to determine which kind of entity it is (a person, book, place...)

Here's what one developer had to say:
We fell in love with Zemanta as soon as we laid eyes on it, and after a chat with their team we found that their SDK was so easy to use that we had a prototype Joomla! plugin in just a couple of hours. Now Joomla! users can quickly and easily add related articles, rich media, in-text links and semantic tags to their blog posts with just a few clicks.
