Taxonomy Induction: Learning Hierarchical Structures

This lecture by the instructor covers the process of taxonomy induction, starting with information extraction from documents to learn relevant terms and their relationships. It explains the use of taxonomies, the task of inducing a taxonomy structure, and the methods for finding hyponyms and hypernyms. The lecture also delves into the construction of hypernym graphs and the cleaning process to determine basic and root concepts, ultimately leading to the creation of a hierarchical taxonomy.
