#semeval #hypernym #nlp #researchpaperwalkthrough 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 ⏩ OUTLINE: 0:00 - Intro and Overview 4:20 - Abstract and Dataset Introduction 5:50 - Pattern based Hypernym Discovery and Hearst Patterns Explained 8:20 - Problem with Hearst Pattern and How to deal with low recall 10:48 - Unsupervised Hypernym Extraction Algorithm 14:04 - Supervised Projection Learning based Hypernym Extraction Algorithm 19:31 - Data Augmentation 22:03 - Hybrid Hypernym Discovery 22:50 - My thoughts and possible suggestions ⏩ Paper:
