The AKSW group announces the first release of DL-Learner, which we open sourced recently. DL-Learner is available for download at its sourceforge.net project page. Its goal is to learn class definitions from examples. To do this, it implements various learning algorithms, supports different input formats, and can make use of different OWL reasoners. DL-Learner provides a command line interface and a separately released PHP web interface.
