Semantic annotation of resources in the semantic web

Abstract

In this chapter, we give a brief introduction into the main idea of the Semantic Web, namely making better use and enabling more intelligent applications for Web-accessible information by accompanying them with machine-understandable, semantic meta data; we sketch the major methodological framework behind, consisting of two intertwined, orthogonal processes, the knowledge process and the knowledge meta process-the latter is concerned with ontology engineering, the former uses ontologies for ontology-based meta-data assignment to Web resources, i.e. for semantic annotation. The major part of the chapter is devoted to the idea of semantic annotation, requirements and functionalities of annotation tools, an example implementation and an overview of the state of research and practice in semantic annotation. © 2007 Springer.
