This paper presents a Web-based environment for visualizing, editing and evaluating multiple ontology alignments. Users can configure their environment according to their needs and tasks, choosing different visualization modes and creating different profiles. They can apply a set of operations on the alignments (filtering, merge, etc.) and evaluate them against a reference one, using classical metrics. Ontology and alignment libraries allow for users storing and searching them in the system. In this demo, all these functionalities will be demonstrated.
