Book Summary: A major limitation of conventional web sites is their unorganized and isolated contents, which is created mainly for human consumption. This limitation can be addressed by organizing and publishing data, using powerful formats that add structure and meaning to the content of web pages and link related data to one another. Computers can "understand" such data better, which can be useful for task automation. The web sites that provide semantics meaning to software agents form the Semantic Web, the Artificial Intelligence extension of the World Wide Web.
In contrast to the conventional Web the "Web of Documents" , the Semantic Web includes the "Web of Data", which connects "things" representing real-world humans and objects rather than documents meaningless to computers.
You will learn how to represent arbitrary fields of human knowledge in a machine-interpretable form using the Resource Description Framework RDF , the cornerstone of the Semantic Web. With the constantly increasing user expectations in web services and applications, Semantic Web standards gain more popularity.
This book will familiarize you with the leading controlled vocabularies and ontologies and explain how to represent your own concepts. Mastering Structured Data on the Semantic Web demonstrates how to represent and connect structured data to reach a wider audience, encourage data reuse, and provide content that can be automatically processed with full certainty.
As a result, your web contents will be integral parts of the next revolution of the Web.
