Domain ontologies are important information sources for knowledge-basedsystems. Yet, building domain ontologies from scratch is known to be a verylabor-intensive process. In this study, we present our semi-automatic approachto building an ontology for the domain of wind energy which is an importanttype of renewable energy with a growing share in electricity generation allover the world. Related Wikipedia articles are first processed in an automatedmanner to determine the basic concepts of the domain together with theirproperties and next the concepts, properties, and relationships are organizedto arrive at the ultimate ontology. We also provide pointers to otherengineering ontologies which could be utilized together with the proposed windenergy ontology in addition to its prospective application areas. The currentstudy is significant as, to the best of our knowledge, it proposes the firstconsiderably wide-coverage ontology for the wind energy domain and the ontologyis built through a semi-automatic process which makes use of the related Webresources, thereby reducing the overall cost of the ontology building process.
