### Question:
WSCKBMatchGraph extends AbstractMatchGraph<Concept, Boolean> { @Override public Boolean match(Concept source, Concept target) { return (kb.equivalent(source,target) || kb.isSubclass(source, target)); } WSCKBMatchGraph(HierarchicalKnowledgeBase kb); @Override Set<Concept> getElements(); @Override Map<Concept, Boolean> getTargetElementsMatchedBy(Concept source); @Override Map<Concept, Boolean> getSourceElementsThatMatch(Concept target); @Override MatchTable<Concept, Boolean> partialMatch(Set<Concept> source, Set<Concept> target); @Override MatchTable<Concept, Boolean> fullMatch(Set<Concept> source, Set<Concept> target); @Override Boolean match(Concept source, Concept target);  }### Answer:
@Test public void testMatch() throws Exception { assertTrue(matchGraph.match(kb.getConcept("con864995873"), kb.getConcept("con1627111892"))); }
