We apply it to induce hypernymy relations by training with <em>is-a</em> pairs. We also present an <em>augmented</em> variant of SPON that can generalize type information learned for in-vocabulary terms to previously unseen ones. An extensive evaluation over eleven benchmarks across different tasks shows that SPON consistently either outperforms or attains the state of the art on all but one of these benchmarks.</p> ER -
