 ABSTRACT      = {In a mixed-initiative dialogue between multiple 
     interlocutors, the ability to construct, to maintain, and to exploit an 
     explicit model of the dialogue partners' beliefs, goals, and plans is 
     indispensable. 
     An \emph{agent model} is required for identifying the objects which the
     dialogue partner is talking about, for planning the appropriate dialogue
     contributions towards achieving the own goals, and for determining the
     effects of planned dialogue contributions on the dialogue partner.}
