Which of the following tools can be used to build a semantic web?

Correct option is A

XML (Extensible Markup Language) and RDF (Resource Description Framework) are essential for building a semantic web. XML provides a flexible structure for data representation, while RDF describes relationships between data objects, enabling machines to understand the semantics of the information.
Important Key Points:
1. Semantic Web: Enhances the web by structuring data in a way that machines can process and interpret relationships.
2. RDF: Provides a standard model for data interchange, enabling linking and understanding of data.
3. XML: Serves as the backbone for defining data formats in semantic web technologies.
Knowledge Booster:
· XSL (Extensible Stylesheet Language): Used for transforming XML data for presentation, not for semantic web.
· Java and Python: Programming languages used for implementation, not for defining semantic structures.
· Applications: Semantic web technologies are widely used in knowledge graphs, Linked Data, and intelligent search engines.
