ABSTRACT
The Konstanz Information Miner is a modular environment,which enables easy visual assembly and interactive executionof a data pipeline. It is designed as a teaching, research andcollaboration platform, which enables simple integration ofnew algorithms and tools as well as data manipulation orvisualization methods in the form of new modules or nodes.In this paper we describe some of the design aspects of theunderlying architecture, briefly sketch how new nodes canbe incorporated, and highlight some of the new features ofversion 2.0.
