- All Implemented Interfaces:
This component adds negative correspondences to the input alignment via a recall optimized matcher. This also means that the input alignment should contain positive correspondences. After applying the recallMatcher given in the constructor, a new alignment is returned which contains positive (equivalence relation) and negative(incompat relation) correspondences. With the help of this alignment, supervised matchers can be trained.
Method SummaryModifier and TypeMethodDescription
static AlignmentThis method returns a training alignment based on a recall alignment and a reference alignment.
(Set<Object> sourceRepresentations, Set<Object> targetRepresentations, Object inputAlignment, Object parameters)Aligns two ontologies/knowledge graphs given as the first and second parameter.
(org.apache.jena.ontology.OntModel source, org.apache.jena.ontology.OntModel target, Alignment inputAlignment, Properties parameters)Aligns two ontologies specified via a Jena OntModel, with an input alignment as Alignment object, and returns the mapping of the resulting alignment.

MatcherYAAAJenaAligns two ontologies specified via a Jena OntModel, with an input alignment as Alignment object, and returns the mapping of the resulting alignment. Note: This method might be called multiple times in a row when using the evaluation framework. Make sure to return a mapping which is specific to the given inputs.

addNegativesThis method returns a training alignment based on a recall alignment and a reference alignment. The training alignment is generated by getting all correspondences in the recall alignment where at least one part is also contained in the reference alignment. If the correspondence is directly in the reference alignment, then it is assumed to be a positive example. If only one part of the correspondence is in the reference alignment, then is is assumed to be a negative correspondence. The result contains the correspondences from the recall alignment, where positive examples have the equivalence relation and negative examples have INCOMPAT relation.
recallAlignment- recall alignment
referenceAlignment- reference alignment which does not need to really be the reference alignment of a track.
- the correspondences from the recall alignment, where positive examples have the equivalence relation and negative examples have INCOMPAT relation
