    Notes: Abstract The general importance of negotiations and bargaining as means of decision making has given rise to considerable research within two broad paradigms. The behavioral paradigm has attempted to discover rationality in specific situations in order to generalize. The formal paradigm has assumed a general rationality which could be applied to specific problems. This strict dichotomy imposes unnecessary restrictions on the use of formal approaches to structure, represent, and support negotiators. Logic-based approaches, such as rule-based formalism, make it possible to blend unique and specific aspects of a problem, with general reasoning mechanisms and rationality postulates. This paper introduces rule-based formalism and discusses its advantages and disadvantages. It attempts to present its ability to represent complex decision processes and to reason using formal structures. The approach is illustrated with several simple examples.

    Notes: Abstract This article explores the use of cognitive mapping as a tool for supporting international negotiation. Cognitive mapping was developed from the research tradition in cognitive psychology that was pioneered by Heider, congruity theory and attribution theory. Applied to political analysis, the technique can be used to represent causal and quasi-causal thinking about a specific policy area. Cognitive maps can be hand-drawn, or, in the case of maps consisting of more than 25 concepts, machine-generated for detailed and systematic analysis. Regardless of the format, cognitive maps can be examined to determine the most central concepts, the explanation of a problem in terms of its root causes and potential consequences, the use of evidence, such as historical analogies, internal consistency, and perceived consequences of policy proposals. Although the technique was designed to represent the views of individuals, cognitive maps can be aggregated to study collective decision-making. Applied to international negotiation, the technique can be employed as a substance-focused tool to represent and integrate knowledge about a specific policy area for use by negotiators. As a process-oriented tool, the technique can be used to help negotiators understand better their own assumptions about a problem, the viewpoints of other parties to the negotiations, and the ways others see their own position. In this mode, the technique has promise for promoting convergence of views and negotiated agreements.

    Notes: Abstract Negotiation is a complex and dynamic decision process during which parties perceptions, preferences, and roles may change. Modelling such a process requires flexible and powerful tools. The use of rule-based formalism is therefore expanded from its traditional expert system type technique, to structuring and restructuring non-trivial processes like negotiation. Using rules we build a model of a negotiation problem. Some rules are used to infer positions and reactions of the parties, other rules are used to modify problem representation when such a modification is necessary. We illustrate the approach with a contract negotiation case between two large companies. We also show how this approach could help one party to realize that negotiations are being carried on against their assumptions and expectations.

    Notes: Abstract This paper introduces the notion of knowledge structuring by schemata. A schema is a chunk of knowledge which generalizes the idea of functional dependence between pertinent concepts (objects). The rules are closely related to the schemata. Moreover the schemata are organized in a hierarchical network which takes into account the relative importance of the concepts. Examples are given in the financial field and the consequences with regards to knowledge engineering are discussed.

    Notes: Abstract The objective of this paper is to introduce a flexible approach to the structuring of negotiations. The process of negotiations with its intricacies is discussed, and drawbacks of quantitative methods are analyzed. The decomposition of the negotiation process into a certain hierarchical structure is presented. This structure is represented with ‘and/or’ trees used for knowledge representation in artificial intelligence. The definitions of flexibility and reactions to the opponent's moves are introduced with the help of a rule-based formalism. The implications of these definitions for the analysis of the negotiation process are presented. The approach is illustrated with a set of hypothetical examples.
