    Notes: Abstract KRISP is a representation system and set of interpretation protocols that is used in the Sparser natural language understanding system to embody the meaning of texts and their pragmatic contexts. It is based on a denotational notion of semantic interpretation, where the phrases of a text are directly projected onto a largely pre-existing set of individuals and categories in a model, rather than first going through a level of symbolic representation such as a logical form. It defines a small set of semantic object types, grounded in the lambda calculus, and it supports the principle of uniqueness and supplies first class objects to represent partially-saturated relationships. KRISP is being used to develop a core set of concepts for such things as names, amounts, time, and modality, which are part of a few larger models for domains including “Who's News” and joint ventures. It is targeted at the task of information extraction, emphasizing the need to relate entities mentioned in new texts to a large set of pre-defined entities and those read about in earlier articles or in the same article.

    Notes: Abstract David Hume is widely believed to be one of the founders of functionalism. His principles of association are seen as an early attempt to articulate a mechanics of the mind akin to Newtonian mechanics. It is argued that this view is based on a failure to appreciate that Hume's skepticism about reason extends to our ability to understand the representation of everyday knowledge. For Hume there are “secret operations” of the mind, operations for which functional explanations are not forthcoming. Hume's place in the history of cognitive science is reevaluated in light of his views on common sense knowledge and belief formation.

    Notes: Abstract A formal, computational, semantically clean representation of natural language is presented. This representation captures the fact that logical inferences in natural language crucially depend on the semantic relation of entailment between sentential constituents such as determiner, noun, adjective, adverb, preposition, and verb phrases. The representation parallels natural language in that it accounts for human intuition about entailment of sentences, it preserves its structure, it reflects the semantics of different syntactic categories, it simulates conjunction, disjunction, and negation in natural language by computable operations with provable mathematical properties, and it allows one to represent coordination on different syntactic levels. The representation demonstrates that Boolean semantics of natural language can be successfully modeled in terms of representation and inference by knowledge representation formalisms with Boolean semantics. A novel approach to the problem of automatic inferencing in natural language is addressed. The algorithm for updating a computer knowledge base and reasoning with explicit negative, disjunctive, and conjunctive information based on computing subsumption relation between the representations of the appropriate sentential constituents is discussed with examples.

    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 Recently, John Bell has proposed that a specific conditional logic, C, be considered as a serious candidate for formally representing and faithfully capturing various (possibly all) formalized notions of nonmonotonic inference. The purpose of the present paper is to develop evaluative criteria for critically assessing such claims. Inference patterns are described in terms of the presence or absence of residual classical monotonicity and intrinsic nonmonotonicity. The concept of a faithful representation is then developed for a formalism purported to encode a pattern of nonmonotonic inference already captured by another. In the main body of the paper these evaluative criteria are applied to assess (negatively) whether C or any conditional logic provides a faithful representation for nonmonotonic patterns of inference captured by inference operators and relations modeling the dynamics of belief change.

    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.
