human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Introduction to the special issue on word sense disambiguation: the state of the art"):
  Abstract: Compte tenu du progres effectue recemment dans le domaine de la desambiguisation du sens des mots, les As. font ici le point sur l'etat de la recherche dans ce domaine depuis ces 50 dernieres annees et considerent les prochaines etapes a franchir. Dans un 1 e r temps, ils passent en revue les principales approches de la desambiguisation du sens des mots : des premieres tentatives effectuees dans le cadre de la traduction automatique aux methodes actuelles basees sur les corpus, en passant par les methodes basees sur l'intelligence artificielle et les methodes utilisant des bases de connaissance. Dans un 2 n d temps, ils examinent les problemes laisses en suspens (le role du contexte, la division des sens, l'evaluation des resultats) et proposent quelques orientations pour la recherche future
