A hypernym describes a more broader concept of the word, wherease, hyponym is more about defining finer granularity. In linguistics, a hyponym is a word or phrase whose semantic field is included within that of another word, its hyperonym or hypernym. In simpler terms, a hyponym is in a type-of relationship with its hypernym. In this video i describe the paper "CRIM at SemEval-2018 Task 9: A Hybrid Approach to Hypernym Discovery" where authors present their winning approach to the SemEval Hypernym task.
⏩ Abstract: This report describes the system developed bythe CRIM team for the hypernym discovery task at SemEval 2018. This system exploits acombination of supervised projection learning and unsupervised pattern-based hypernym discovery. It was ranked first on the 3 sub-tasks for which we submitted results
