Semantic annotation is part of the Semantic Web vision. The Annotation Ontology is a model that have been proposed to represent any annotations in standard RDF. The NCBO Annotator Web service is a broadly used service for annotations in the biomedical domain, offered within the BioPortal platform and giving access to more than 350+ ontologies. This paper presents a new output format to represent the NCBO Annotator results in RDF with the Annotation Ontology. We briefly present both technologies and describe the mappings to enable the representation. A Java library is available to parse the current JSON outputs to RDF/XML format. By rendering results in RDF, we make the annotations generated by the NCBO Annotator follow the Semantic Web standards making possible among other things to offer them as linked data.
