State-of-the-art bootstrapping systems rely on expert-crafted semantic constraints such as negative categories to reduce semantic drift. Unfortunately, their use introduces a substan- tial amount of supervised knowledge. We present the Relation Guided Bootstrapping (RGB) algorithm, which simultaneously ex- tracts lexicons and open relationships to guide lexicon growth and reduce semantic drift. This removes the necessity for manually craft- ing category and relationship constraints, and manually generating negative categories.
