  Domain ontologies are important information sources for knowledge-based
systems. Yet, building domain ontologies from scratch is known to be a very
labor-intensive process. In this study, we present our semi-automatic approach
to building an ontology for the domain of wind energy which is an important
type of renewable energy with a growing share in electricity generation all
over the world. Related Wikipedia articles are first processed in an automated
manner to determine the basic concepts of the domain together with their
properties and next the concepts, properties, and relationships are organized
to arrive at the ultimate ontology. We also provide pointers to other
engineering ontologies which could be utilized together with the proposed wind
energy ontology in addition to its prospective application areas. The current
study is significant as, to the best of our knowledge, it proposes the first
considerably wide-coverage ontology for the wind energy domain and the ontology
is built through a semi-automatic process which makes use of the related Web
resources, thereby reducing the overall cost of the ontology building process.
