Cluuz Search Engine
http://www.cluuz.com/

Cluuz generates easier to understand search results through patent pending semantic cluster graphs, image extraction, and tag clouds. The difference between standard search engines and Cluuz is in the fact that Cluuz does some work for you. A standard search engine shows links in a list. Cluuz instead peers into the searched web pages, extracts important terms and images, clusters them and gives them in chart format (semantic graph) and in a tag cloud where you can click on any entity to further focus your search.
