In order to overcome human and time resource problems in the task of ontology design, we propose to combine the LExO approach to learning expressive ontology axioms from textual definitions with Relational Exploration - a technique based on the well-known attribute exploration algorithm from FCA which is used to interactively clarify underspecified logical dependencies. By forcing particular modeling decisions the exploration of classes and class extension relationships guarantees completeness with respect to a certain logical fragment and increases the overall quality of the ontology. Providing an implementation as well as an example, we demonstrate how ontology learning and exploration complement each other in a synergetic way.
