Renewable energy ontology

Renewable energy applications nowadays are a critical factor to their success. Making sure that a specific information, service or product from an online provider is reliable and trustworthy may sometimes be a difficult task. The World Wide Web (WWW) is an open environment in which every person is allowed to populate some information. The accuracy or reliability of such information, to some extent, is unknown, and therefore cannot be trusted. In this paper, we argued that using ontologies may form a useful tool to find the best renewable energy provider. The contribution of this paper is to develop ontology concepts for measuring such "goodness". Common and frequent concepts from five popular and trusted online renewable energy providers were extracted, refined, and then checked against nine other online providers. These providers are also judged by experts who are renewable energy specialists. The results discussed in this paper have shown that the proposed approach has achieved high matching score to the experts' judgments.
