Hyponymy　is　a　basic　semantic　relation.　There　are　still　many　error　relations　in　the　automatic　acquired　hyponymy　relations　from　free　text.　They　will　affect　the　building　of　ontologies.　We　present　an　iterative　method　of　hyponymy　verification　between　Chinese　terms　based　on　concept　space.　We　give　the　definition　of　concept　space　about　a　group　of　candidate　hyponymy　relations　initially.　Then　a　set　of　hyponymy　features　based　on　concept　space　are　acquired.　These　features　are　changed　into　production　rules.　Finally　the　candidate　hyponymy　relations　are　iterative　verified　with　those　production　rules.　Experimental　results　demonstrate　good　performance　of　the　method.　©　2009　Springer-Verlag.
