Summary. Ontology Learning greatly facilitates the construction of ontologies by the ontology
engineer. The notion of ontology learning that we propose here includes a number of complementary
disciplines that feed on different types of unstructured and semi-structured data in
order to support a semi-automatic, cooperative ontology engineering process. Our ontology
learning framework proceeds through ontology import, extraction, pruning, and refinement,
giving the ontology engineer a wealth of coordinated tools for ontology modelling. Besides
of the general architecture, we show in this paper some exemplary techniques in the ontology
learning cycle that we have implemented in our ontology learning environment, KAON
Text-To-Onto.
