DESCRIPTION:Topology of the conceptual network of language\nby Motter\, de
  Moura\, Lai and Dasgupta "Phys. Rev. E\, Vol. 65\, 065102 (2002)":http://
 prola.aps.org/abstract/PRE/v65/i6/e065102\n\nWe define two words in a lang
 uage to be connected if they express similar concepts. The network of conn
 ections among the many thousands of words that make up a language is impor
 tant not only for the study of the structure and evolution of languages\, 
 but also for cognitive science. We study this issue quantitatively\, by ma
 pping out the conceptual network of the English language\, with the connec
 tions being defined by the entries in a Thesaurus dictionary. We find that
  this network presents a small-world structure\, with an amazingly small a
 verage shortest path\, and appears to exhibit an asymptotic scale-free fea
 ture with algebraic connectivity distribution.
