today we released DL-Learner Build 2009-05-06. DL-Learner [1] is a tool
for learning OWL class expressions [2] from examples and background
knowledge. It extends Inductive Logic Programming (ILP) to Description
Logics and the Semantic Web.

Downloads are available at [3]. For a list of the most important changes
since the previous release (Build 2008-10-13), see the Changelog [4].
Some notable features in this release are:

 * a new learning algorithm (CELOE) designed specifically for extending
   OWL ontologies
 * a Protege plugin [5] using CELOE
 * a manual [6] for getting started using DL-Learner
 * performance improvements through stochastic methods
 * more learning examples, unit tests, code quality improvements

DL-Learner can be used to:

 * solve general supervised Machine Learning problems using ontologies
   as background knowledge (given as OWL files, SPARQL endpoints, etc.),
   e.g. it was used to predict whether chemicals can cause cancer [7]
 * help knowledge engineers by learning definitions and subclass axioms
   (see Protege plugin and another one for OntoWiki is in progress)
 * generating user recommendations when browsing knowledge bases

DL-Learner is developed at the AKSW [8] research group. I'd like to
thank all contributors, in particular active developers [9] and everyone
who send us valuable feedback.

Kind regards,

Jens Lehmann
