Take a look at this. Eyeplorer is knowledge program that scans the web and organises the facts into a user friendly chart. Items that appear on the chart can be scrolled over to reveal their detail and link you to the website they came from. If you require that information it can simply be dragged from the chart to the accompanying writing pad, allowing you to collate notes throughout your search of the topic.
Eyeplorer is a development on most search engines that only give you a list of sites to explore. You would normally have to visit each site and discern if it is what you require. Eyeplorer rationalises some of this activity into one screen and gives you the power to manipulate the search findings to your own needs.
