The document discusses the concept of the Semantic Web, outlining its aim to facilitate machine communication by providing meaningful data and formalized knowledge. It highlights various technologies, frameworks, and standards like RDF and ontologies that enable interoperability among different applications. Additionally, it addresses the challenges in developing the Semantic Web and its implications for areas such as electronic commerce and knowledge representation.

12. So what it aims at???In short aims at……….The goal of the semantic web is to be “a web talking to machines”I know What you mean……Providing meaningful information Supplying the web withformalized knowledge in addition to its actual informal contentDesigning a framework for interoperabilityaccessible by computers.12
