In this paper, we describe an ontology-based method of selection of test examples for relation extraction, as well as a method of their validation apt to be carried out by ordinary language-speakers. The results will be used to validate performance of various relation extraction algorithms. In performed tests we utilize the ResearchCyc ontology and demonstrate the method's performance in gathering examples from Polish texts.
