A GUI for Visualising and Manipulating Multiple Ontology Alignments

International audience; This paper presents a Web-based environment for visualising and manipulating multiple ontology alignments at schema-level. While most solutions are limited to the visualisation of single alignments and are still provided as part of specific standalone matching systems, we propose an open environment that is not bound to any specific system. Within this graphical environment, users can manually create, suppress and edit correspondences and apply a set of operations on alignments (filtering, merge, difference, etc.). Evaluating multiple alignments, against a reference one, can also be carried out using classical evaluation metrics. In this demo, all these tasks will be demonstrated.
