Semantic Web is a system that allows machines to understand and respond to complex human requests based on their meaning. It extends the current web by incorporating standards, metadata, ontologies, and semantic content. Coursera's Semantic Web catalogue teaches you the foundational knowledge and technical skills needed to understand and work with the Semantic Web and linked data. You'll learn how to build and use ontologies, query and manipulate semantic data using SPARQL, create and implement semantic web services, and understand the role of AI in the Semantic Web. This skill enhances your potential as a web developer, data analyst, or digital marketer with a deep understanding of how semantic technologies can improve user experience, data interoperability, and web-based services.
