MEMO GRAPH: An Ontology Visualization Tool for Everyone

This paper presents a user-friendly tool, called MEMO GRAPH, for visualizing and navigating ontologies. Compared to related work, MEMO GRAPH is designed to be used by everyone, including ontology experts and users not familiar with ontologies. It provides an accessible and understandable user interface that follows the “design-for-all” philosophy. Precisely, it offers an Alzheimer's patients-friendly interface. The MEMO GRAPH ontology visualization tool is integrated in the CAPTAIN MEMO memory prosthesis and it is applied for visualizing a small-scale ontology (PersonLink) and a large-scale ontology (DBpedia). We discuss the encouraging results derived from the preliminary empirical evaluation, which confirms that MEMO GRAPH is an intuitive and usable ontology visualization tool.
