A Graph-Based Algorithm for Inducing Lexical Taxonomies from Scratch

  title={A Graph-Based Algorithm for Inducing Lexical Taxonomies from Scratch},
  author={Roberto Navigli and Paola Velardi and Stefano Faralli},
In this paper we present a graph-based approach aimed at learning a lexical taxonomy automatically starting from a domain corpus and the Web. Unlike many taxonomy learning approaches in the literature, our novel algorithm learns both concepts and relations entirely from scratch via the automated extraction of terms, definitions and hypernyms. This results in a very dense, cyclic and possibly disconnected hypernym graph. The algorithm then induces a taxonomy from the graph. Our experiments show… CONTINUE READING
