    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»

    Techniques are presented to improve the time taken by autonomous scheduling agents to schedule meetings and to accommodate as much as possible high priority meetings in an overconstrained situation. The first of these objectives is attained by building a temporal abstraction hierarchy of the calendar and negotiating at successively lower levels of the hierarchy, thereby pruning away unpromising pa...

    In the domain of distributed AI (DAI), two negotiation mechanisms (one strict and one tolerant), and a negotiation strategy, for the situation where agents' goals are common knowledge, but the worths they attach to those goals are private are presented. All possible prototypical classes of (non-conflict) encounters are analyzed, and it is shown where the strategy and mechanisms result in stable an... View full abstract»

    In multi-agent systems where each agent has a different goal, agents must be able to resolve conflicts arising in the process of achieving their goals, without sufficient knowledge about other agents. A method is presented for conflict resolution in which agents are allowed to have partial knowledge about other agents. A negotiation protocol is proposed for conflict resolution under a set of assum... View full abstract»

    A mechanism is presented for negotiating to resolve conflicts that arise when autonomous agents need to agree on a collection of operations in order to achieve a goal. These conflicts arise when the agents have different policies as to which operations are acceptable. The authors' mechanism protects the privacy of the agents because they are not required to exchange information freely about their ... View full abstract»

    The self-triggering approach presented in this paper is a novel architecture for active database systems. It provides a high-level reflective rule language, rich modelling tools and a clear semantics of dependencies among data elements. Under this approach, rules that are data-driven by nature are handled by a mechanism that utilizes their semantic properties, while rules that are event-driven by ... 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»

    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»

    Publication Year: 1993, Page(s):3 - 12
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (916 KB)

    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...

    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»

    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»
