Visual presentation of mappings between biomedical ontologies

Ontology mapping focuses on finding correspondences between concepts from different ontologies. While the amount of available ontologies is increasing, also the number of mappings between them is getting higher. Visualization techniques can be used to help researchers in forming a picture of this information. In the paper we present a visual presentation of mappings between BioPortal ontologies. We present results in the form of a graph where identified communities of tightly connected ontologies are shown.We use metrics such as Betweenness Centrality and Community Detection
