    14 First, the commonly used CN2 learner's description is given. That is followed 
    15 by documentation of the common framework of classes that enable customization 
    16 of the rule induction process.

    19 CN2 Rule Induction Algorithm 
    20 ============================ 
     12Orange implements several supervised rule induction algorithms 
     13and rule-based classification methods. First, there is an implementation of the classic  
     14`CN2 induction algorithm <http://www.springerlink.com/content/k6q2v76736w5039r/>`_.  
     15The implementation of CN2 is modular, providing the oportunity to change, specialize 
     16and improve the algorithm. The implementation is thus based on the rule induction  
     17framework that we describe below.
