Semantic heterogeneity caused by the use of different ontologies to describe the same topics represents an obstacle for many data integration tasks on the Web of data, in particular, discovering relevant repositories for interlinking and comparing repositories with respect to the coverage of specific domains. To facilitate these tasks, map-pings between schema terms are needed alongside the links between in-stances. Currently, explicitly specified schema-level mappings are scarce in comparison with instance-level links. However, by analyzing existing instance-level links it is possible to capture correspondences between classes to which these instances belong.
