    Redux' is a subset of the full REDUX model. The latter performs problem solving. In contrast, Redux' acts only as a decision maintenance server. It takes objects of types defined in an ontology of decision components and maintains dependencies between them. Redux' is domain-independent. The dependency relationships are maintained on the basis of proposition type and not content, except for some st... View full abstract»

    This work presents the formalization of pragmatical notions based on the relation between agents and sentences of the language which they use to communicate to each other. The approach is based on R. Martin's “Toward a Systematic Pragmatics” (1959). A pragmatical metalanguage expresses agent's acceptance relation with an object language. Some set constructions are used to illustrate th... View full abstract»

    Data integration in a multidatabase environment needs to be flexible and dynamic. We propose a framework that supports `open' architecture in which every system on the network can exchange data, it requires a rich data structure and a powerful negotiation protocol. We also discuss the contract/negotiation used in the contracting mechanism and correspond its features with the requirements of the pr... View full abstract»

    An architectural specification of independent communicating agents is described. Such agents are designed for use in an environment which is most suitably represented as a graph or network and an example of one such environment is given based on the structured document graph paradigm. The specifications extend agent architectures in a natural way so that the complexities found in distributed syste... View full abstract»

    This paper presents a model for creating and modifying complex objects that are distributed in a network of autonomous cooperating agents. The information that agents are willing to share with others in the federation is uniformly represented as inter-related objects. This defines a distributed object graph that spans over the entire federation of agents. Complex objects form a connected subgraph ... View full abstract»

    The goal of the author is to examine the question “to what end do we study cooperative dialogue?” Based on an analysis of previous work, he argues that despite more than a decade of research in artificial intelligence, our understanding of the general principles governing cooperative discourse has improved very little. Furthermore, he suggests that the standard approach of modeling exa... View full abstract»

    Managing interschema knowledge is an essential task when dealing with cooperative information systems. We propose a logical approach to the problem of both expressing interschema knowledge, and reasoning about it. In particular, we set up a logical language for expressing semantic interdependencies between, classes belonging to different database schemas, and show that reasoning over such interdep...

    Introduces a novel mechanism for the updating process in a distributed knowledge base to allow flexible responses to cooperative interaction. The paper focuses upon the intelligent change of a given problem description according to some interaction. This feature is important because one often does not have handy the complete problem specification right from the beginning. Another motivation is the... View full abstract»

    Previously, E. Ephrati and J.S. Rosenschein (1991) introduced the Clarke Tax as an appealing way to achieve a consensus in a multi-agent environment. As noted there, however, the Clarke Tax has several drawbacks from the viewpoint of DAI, such as the fact that participating agents can maintain no privacy regarding their preferences, and the need for a central vote-counting agent. E. Ephrati and J.... View full abstract»

    Describes techniques to restrict and to heuristically control relaxation of deductive database queries. The process of query relaxation provides a user with a means to automatically identify new queries that are related to the user's original query. However, for large databases, many relaxations may be possible. The methods to control and restrict the relaxation process introduced in this paper fo... View full abstract»

    The authors are concerned with heterogeneous agents in dynamic domains, where an agent may have to interact with varying number and various types of agents. To assist the inevitable computational limitations involved in reasoning and deciding within interactions, a focusing mechanism is essential in the dynamic update of an agent's knowledge about other agents. The authors claim that this focusing... View full abstract»
