**What is a semantic web?**
The semantic web is a framework that enhances the existing web by enabling data to be shared and reused across application, enterprise, and community boundaries. It utilizes structured data and ontologies to give meaning to information, allowing machines to understand and interpret data contextually, improving search and data integration. By utilizing formats like RDF (Resource Description Framework) and OWL (Web Ontology Language), the semantic web aims to make web content more accessible and interconnected, ultimately providing richer user experiences and smarter applications.
