This paper introduces JNCC2, the Java implementation of the Naive Credal
Classifier2 (NCC2). JNCC2 is open source; it is hence freely  
available together
with manual, sources and javadoc documentation.
JNCC2 implements the Naive Credal Classifier2 (NCC2), i.e., an  
extension of
Naive Bayes Classifier (NBC) towards imprecise probabilities. NCC2 is  
designed
to return robust classification, even on small and/or incomplete data  
sets. A
peculiar feature of NCC2 is that it returns imprecise classifications  
(i.e., more
than one class) when faced with doubtful instances. The empirical  
results of
Corani and Zaffalon (2007) have shown that NCC2 returns imprecise  
judgments
on instances whose classification is truly doubtful; in fact, NBC  
achieves a much
higher classification accuracy on the instances precisely classified  
by NCC2, than
on those imprecisely classified by NCC2.
