In this paper we propose an instance based method for lexical entailment and apply it to automatic ontology population from text. The approach is fully unsupervised and based on kernel methods. We demonstrate the effectiveness of our technique largely surpassing both the random and most fre- quent baselines and outperforming current state-of-the-art unsupervised approaches on a benchmark ontology available in the liter- ature.
