Abstract

State-of-the-art research on automated learning of ontologies from

text currently focuses on inexpressive ontologies. The acquisition
of complex axioms involving logical connectives, role
restrictions, and other expressive features of the Web Ontology
Language OWL remains largely unexplored. In this paper, we present
a method and implementation for enriching inexpressive OWL
ontologies with expressive axioms which is based on a deep
syntactic analysis of natural language definitions. We argue that
it can serve as a core for a semi-automatic ontology engineering
process supported by a methodology that integrates methods for
both ontology learning and evaluation. The feasibility of our
approach is demonstrated by generating complex class descriptions
from Wikipedia definitions and from a fishery glossary provided by
the Food and Agriculture Organization of the United Nations.
