description
WEKA project was initiated in early 1992 by the New Zealand Government, and more than 21 years have elapsed since the first public release of WEKA. Along that period of time, the software has been rewritten entirely from scratch once. Initially it was written in C programming language, and along the time it became a burden and they have moved to Java. These days, WEKA enjoys its acceptance in both academic and business levels because, WEKA is an open source project and it has an active community.
