We present a self-contained formulation of the Nonlinear Schrodingerhierarchy and its Yangian symmetry in terms of deformed oscilator algebra (Z.F.algebra). The link between Yangian Y(gl(N)) and finite W(gl(pN),N.gl(p))algebras is also illustrated in this framework.Comment: Proceedings of QGIS-99, Prague, June 17-19 1999, 7 page
