This article emphasizes the combined requirements of computer systems and humanistics. In cooperative computing, negotiations can be used as a basic paradigm by which different roles and their requisites can be identified—the facilitator, the mediator, and the negotiator. The negotiation‐cooperation process has a logical sequence of agreements, definition of terms, objectives, mode of operation, common security measures concerning integrity and liability, handling protocols, etc. The cooperation is based on models of the subject and the partners—i.e., a minimum of three models should be matched. The usual methods of human negotiations supported by metacommunication should have a computer‐realizable substitute. All these subjects are outgrowths of recent research in artificial intelligence (knowledge‐based systems) and cognitive psychology; some experiences are reported in the field. However, the main task is human‐oriented—education of people for this new powerful means of coexistence.
