Applied ontology
open-in-new
<p>Applied ontology is the application of <a href="/facts/Ontology/QJKTsEIJ">Ontology</a> for practical purposes. This can involve employing ontological methods or resources to specific domains, such as <a href="/facts/Management/8KMV9yMM">management</a>, <a href="/facts/Interpersonal_relationship/rxgcYdBC"> relationships</a>, <a href="/facts/Biomedicine/DWFT3MFG">biomedicine</a>, <a href="/facts/Information_science/HGG3e3Jv">information science</a> or <a href="/facts/Geography/TRd1Toyo">geography</a>. Alternatively, applied ontology can aim more generally at developing improved methodologies for recording and organizing knowledge. </p><p>Much[<i>quantify</i>] work in applied ontology is carried out within the framework of the <a href="/facts/Semantic_web/NFHo9dB7">Semantic Web</a>. Ontologies can structure data and add useful semantic content to it, such as definitions of classes and relations between entities, including subclass relations. The <a href="/facts/Semantic_web/NFHo9dB7">semantic web</a> makes use of languages designed to allow for ontological content, including the <a href="/facts/Resource_Description_Framework/WMufyukm">Resource Description Framework</a> (RDF) and the <a href="/facts/Web_Ontology_Language/jkr0IGn8">Web Ontology Language</a> (OWL). </p>
