getEntityMapping

public AMapping getEntityMapping(String endpoint1,
                                 String endpoint2,
                                 String namespace1,
                                 String namespace2)

Specified by:

getEntityMapping in interface OntologyClassMapper

getMappingClasses

public AMapping getMappingClasses(String endpoint1,
                                  String endpoint2,
                                  String namespace1,
                                  String namespace2)

Computes mapping between classes in two given endpoints by using the owl:sameAs links. If no such links exists between the two endpoints, the fallback solution is used

Parameters:

endpoint1 - Source endpoint for the class mapping

endpoint2 - Target endpoint for the class mapping

namespace1 - Namespace for the source endpoint

namespace2 - Namespace for the target endpoint

Returns:

Mapping of classes from source to target weighted with number of owl:sameAs links or fallback weight based on matching properties
