A new framework for the induction of logical decision trees is presented. Differently from the original setting, tests at the tree nodes are expressed with Description Logic concepts. This has a number of advantages: expressive terminological languages are endowed with full negation, thus allowing for a more natural division of the individuals at each test node; these logics support the standard ontology languages for representing knowledge bases in the Semantic Web. A top-down method for inducing terminological decision trees is proposed as an adaptation of well-known tree-induction methods. This offers an alternative way for learning in Description logics as concept descriptions can be associated to the terminological trees. A new version of the System TermiTIS, implementing the methods, is experimentally evaluated on ontologies from popular repositories.
