  In this era of "Services" everywhere, with the explosive growth of E-Commerce
and B2B transactions, there is a pressing need for the development of
intelligent negotiation systems which consists of feasible architecture, a
reliable framework and flexible multi agent based protocols developed in
specialized negotiation languages with complete semantics and support for
message passing between the buyers and sellers. This is possible using web
services on the internet. The key issue is negotiation and its automation. In
this paper we review the classical negotiation methods and some of the existing
architectures and frameworks. We are proposing here a new combinatory framework
and architecture, NAAS. The key feature in this framework is a component for
prediction or probabilistic behavior pattern recognition of a buyer, along with
the other classical approaches of negotiation frameworks and architectures.
Negotiation is practically very complex activity to automate without human
intervention so in the future we also intend to develop a new protocol which
will facilitate automation of all the types of negotiation strategies like
bargaining, bidding, auctions, under our NAAS framework.
