In this paper we demonstrate methods of improving both the recall and the precision of automatic methods for extraction of hyponymy (IS_A) relations from free text. By applying latent semantic analysis (LSA) to filter extracted hyponymy relations we reduce the rate of error of our initial pattern-based hyponymy extraction by 30%, achieving precision of 58%. Applying a graph-based model of noun-noun similarity learned automatically from coordination patterns to previously extracted correct hyponymy relations, we achieve roughly a five-fold increase in the number of correct hyponymy relations extracted.
