%X this paper presents an approach to the automatic extraction of hyponyms and hyperonyms. in particular, it proposes an information extraction method that is specially suited for identifying pairs of hyponym-hyperonym by using a set of spanish lexical patterns. it also proposes a symmetric weighting scheme of pairs/patterns whose goal is to enhance the confidence of the extraction method. the effectiveness of the proposed approach was evaluated by extracting hyponyms from a given vocabulary of hyperonyms. results show the usefulness of the proposed extraction method as well as the relevance of the pairs/patterns weighting scheme.
