A Browser-based Tool for Collaborative Distributed Annotation for the Semantic Web
Onni Valkeapää, Eero Hyvönen · 2006
This paper presents a prototype of an ontology-based semantic annotation tool Saha. The tool eases the process of creating ontological descriptions of documents by providing a simple user interface that hides the complexity of ontologies from annotators. Saha is used with a web browser, and it supports collaborative distributed creation of metadata by centrally storing annotations, which can be viewed and edited by different annotators. Concepts defined in external ontologies can be imported and used in annotations by connecting Saha to ontology servers. The tool is being tested in practical semantic portal projects.
