Semantic Web
open-in-new
<p>The Semantic Web, sometimes known as Web 3.0, is an extension of the <a href="/facts/World_Wide_Web/wvnTrWFq">World Wide Web</a> through standards set by the <a href="/facts/World_Wide_Web_Consortium/lGWmhF6M">World Wide Web Consortium</a> (W3C). The goal of the Semantic Web is to make <a href="/facts/Internet/Xw1rVvJU">Internet</a> data <a href="/facts/Machine-readable/YA2qAshK">machine-readable</a>. </p><p>To enable the encoding of <a href="/facts/Semantics/1L4WwLAP">semantics</a> with the data, technologies such as <a href="/facts/Resource_Description_Framework/WMufyukm">Resource Description Framework</a> (RDF) and <a href="/facts/Web_Ontology_Language/jkr0IGn8">Web Ontology Language</a> (OWL) are used. These technologies are used to formally represent <a href="/facts/Metadata/qt35z79C">metadata</a>. For example, <a href="/facts/Ontology_(information_science)/SQlhl6lp">ontology</a> can describe <a href="/facts/Concept/VWB6yhQp">concepts</a>, relationships between <a href="/facts/Entity%25E2%2580%2593relationship_model/U8A0mwYe">entities</a>, and categories of things. These embedded semantics offer significant advantages such as <a href="/facts/Reasoning_engine/rXkm48cY">reasoning</a> over data and operating with heterogeneous data sources. These standards promote common data formats and exchange protocols on the Web, fundamentally the RDF. According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries." The Semantic Web is therefore regarded as an integrator across different content and information applications and systems. </p>
