PubOnto's inter-ontology filter mode, which shows intersecting articles between different ontologies. In the ontology tab that is open, a user specifies a node/categorical concept of interest by clicking on its name, and then right clicks on the name of this concept, and a context menu appears. Select the "Map Result to Other Ontologies" activates PubOnto's automatic mapping of one ontological term to the terms in another ontology.
