ABSTRACT
A Semantic Web can be thought of as a web that is highly intelligent and sophisticated so that one needs little or no human intervention to carry out tasks such as scheduling appointments, coordinating activities, and searching for complex documents, as well as integrating disparate databases and information systems. While much progress has been made toward developing such an intelligent web, there is still a lot to be done. For example, technologies such as ontology matching, intelligent agents, and markup languages are contributing a lot toward developing the Semantic Web. Nevertheless, one still needs a human to make decisions and take actions. Since the 2000s there have been many developments on the Semantic Web. The World
Wide Web Consortium (W3C) is specifying standards for the Semantic Web (World Wide Web Consortium, https://www.w3c.org). These standards include specifications for eXtensible Markup Language (XML), RDF, and interoperability.
