Contextualized visualization of ontologies and ontology networks

Contextualized visualization of ontologies and ontology networks is addressed here via visualization of ontology and ontology mappings. The idea is to enable the user to browse through an ontology inside a context of related networked ontologies, where the context is defined through the mappings between the ontologies. The proposed visualization consists of two parts. First, a pair of ontologies is visualized in an intelligent way and second, alignment of these two ontologies is visualized as links between the related concepts. The proposed approach is implemented in cONTOext as a Flash application integrated within the Facebook plug-in architecture. The extended approach is implemented in OntoConto as plug-in to a NeOn Toolkit platform where it is seamlessly integrated with the other technologies. Namely, integration inside the existing NeOn Toolkit provides an easy access to the loaded ontologies, a possibility to edit them and, enables the user to access several different alignments between the ontologies.
