The aim of this Paper is to present our model for a generic and flexible negotiation Service and its implementation in Computer Supported Collaborative Work (CSCW) environments. Within a cooperative work environment, users naturally need negotiation support mechanisms to study possible alternatives in group decision making. The objective of our work is to build a negotiation model independent of any particular application field. Contrary to studied models, our model focuses on formalizing the negotiation from three Points of view: exchanged information between the agents to negotiate (the language), the way this information is exchanged (the protocol) , and the internal behavior of an agent (the tactics). In addition to a Separation of the Problems involved in each one of these three facets of the negotiation, this approach allows also a greater flexibility than traditional Systems dedicated to one kind of Problems. We Chose to use a transactional approach based on Speech acts to develop our axiom based negotiation model which has been implemented as a negotiation Service in our CSCW environment DisCOO [l, 2]. After the tackled Problem presentation, we will expose the state of the art, then the proposed negotiation formal model, and, finally, the implementation.
