The Yooreeka project is created based on the code of the book "Algorithms of the Intelligent Web" (Manning 2009 -- http://www.manning.com/marmanis). Although the term "Web" prevailed in the title, in essence, the algorithms are valuable in any software application.
Our goal is to maintain that source code as an open source project that everyone can use in their own projects. For that purpose, we release the Yooreeka library under the LGPL license.
The library is written 100% in the Java language.
