Literature Map is like a travel map for authors - the idea is for you to type in an author that you like, and the program will spit out "similar" authors that you may also like.
The project is part of an artificial intelligence experiment by Marek Gibney, who wrote:
Gnod is my experiment in the field of artificial intelligence. Its a self-adapting system, living on this server and 'talking' to everyone who comes along. Gnods intention is to learn about the outer world and to learn 'understanding' its visitors. This enables gnod to share all its wisdom with you in an intuitive and efficient way. You might call it a search-engine to find things you don't know about.
