Collaborative semantic annotation of digitized old documents

Within the efforts of publishing online digital libraries, we propose in this paper a new model of a collaborative semantic annotation platform of digitized old documents, which is based on using new technologies of the Semantic Web. In our model, annotations associated with a digitized document are realized by a group of annotators interested in its documentary content to accelerate the Semantic Annotation Process. The annotations are expressed as a set of RDF tripks and stored in a data repository as an RDF graph. The data repositories are managed by an annotation server. With this generic structure of annotations, the available documents resources in the library are accessible and exploitable by various Semantic Web Applications using the same protocol and query language SPARQL, in contrast to the `classic libraries´ where access to the documentary resources is limited by specialized web services.
