A family of fuzzy orthogonal projection models for monolingual and cross-lingual hypernymy prediction

C Wang, Y Fan, X He, A Zhou - The world wide web conference, 2019 - dl.acm.org
Hypernymy is a semantic relation, expressing the “is-a” relation between a concept and its
instances. Such relations are building blocks for large-scale taxonomies, ontologies and …
