Instances and concepts in distributional space
Instances ({``}Mozart{''}) are ontologically distinct from concepts or classes ({``}composer{''}). Natural language encompasses both, but instances have received comparatively little attention in distributional semantics. Our results show that instances and concepts differ in their distributional properties. We also establish that instantiation detection ({``}Mozart {--} composer{''}) is generally easier than hypernymy detection ({``}chemist {--} scientist{''}), and that results on the influence of input representation do not transfer from hyponymy to instantiation.
