Automatic　acquisition　of　semantic　relations　is　an　important　problem　in　knowledge　acquisition.　We　present　a　method　of　spatial　structure　analysis　of　candidate　Chinese　hyponymy　based　on　concept　space　and　use　them　to　identify　candidate　hyponymy.　Firstly　a　group　of　candidate　hyponymy　relations　is　imported　into　concept　space.　Secondly　we　analyze　the　basic　spatial　structure　of　concept　space　including　concept　nodes　and　relation　edges.　More　identified　features　based　on　the　spatial　structure　analysis　are　given　and　used　to　identify　hyponymy　relations.　Experimental　results　show　that　the　spatial　structure　is　very　useful　to　the　identification　of　hyponymy.　©　2013　ACADEMY　PUBLISHER.
