The document discusses the adoption of semantic web technologies. It notes that while tools and specifications have matured, applications are now coming to the forefront. It provides examples of semantic web deployments in various domains like digital libraries, eGovernment, healthcare and by major companies. Real-world applications include data integration, intelligent portals and knowledge management systems. Overall adoption is increasing but skills and training remain obstacles.
4. The 2007 Gartner predictions By 2017, we expect the vision of the Semantic Web […] to coalesce […] and the majority of Web pages are decorated with some form of semantic hypertext. By 2012, 80% of public Web sites will use some level of semantic hypertext to create SW documents […] 15% of public Web sites will use more extensive Semantic Web-based ontologies to create semantic databases (note: “semantic hypertext” refers to, eg, RDFa, microformats with possible GRDDL, etc.) Source: “Finding and Exploiting Value in Semantic Web Technologies on the Web”, Gartner Research Report, May 2007
