Report on Methods and Algorithms for Linking User-Generated Semantic Annotations to Semantic Web and Supporting their Evolution in Time

The INSEMTIVES project is concerned with increasing the amount of annotations available for various kinds of content, predominantly in a structured form using controlled vocabularies and aligned to content on the Semantic Web. In this deliverable we discuss solutions for generating links to external resources on the Semantic Web from structured annotations and how these annotations can evolve in time if controlled vocabularies, referred in these annotations, change. We discuss existing techniques for both problems and propose a set of methods (a) applicable to interlink various kinds of content and (b) to support the evolution of annotations in time.
