The paper describes a system for semantic relations extraction, based on the usage of semantic information provided by ResearchCyc and shallow syntactic features. The experiments have shown that the external knowledge, encoded as super-class information from ResearchCyc without any word sense disambiguation, significantly contributes to improve overall performance of the system. The problem of the lack of coverage may be overcome by the usage of other large-scale knowledge bases, such as DBpedia. For future work, we will try to use the Cyc inference engine to obtain implicit information about nominals in addition to the information about their
