Towards supporting annotation for existing web pages enabling hyperstructure-based searching

This paper discusses the requirements and tasks in annotating existing Web pages with additional structural and semantic information. It suggests annotating existing Web pages with the concepts of a domain model, and annotating the links between the Web pages with the relations between these concepts. It also suggests explicitly representing high-level hypermedia structures, so-called hypertext composites and contexts, and annotating the corresponding composite and context pages with such structures. RDF and RDF Schema are adopted to represent the domain models and the resulting annotations. The architecture of a prototype annotation tool is outlined and corresponding requirements for automatic annotation support are discussed
