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 focus the relaxation process and make it more efficient. User restrictions over the database domain may be expressed as user constraints. This paper describes how user constraints can restrict relaxed queries. Also, a set of heuristics based on cooperative answering techniques are presented for controlling the relaxation process. Finally, the interaction of the methods for relaxing queries, processing user constraints, and applying the heuristic rules is described.<<ETX>>","PeriodicalId":270352,"journal":{"name":"[1993] Proceedings International Conference on Intelligent and Cooperative Information Systems","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122852675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 assumptions that makes the world of agents resemble a real system. The authors' negotiation protocol can be applied to conflicts on both consumable and reusable types of resources. It is shown that agents can cooperate with each other even when information about resources is incomplete. Some results on a negotiation protocol are presented.<<ETX>>","PeriodicalId":270352,"journal":{"name":"[1993] Proceedings International Conference on Intelligent and Cooperative Information Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134506706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such an environment consists of heterogeneous and autonomous local database systems. Applications in such an environment use several resources and services.

We introduce a formal object-oriented language capable of dealing with these requirements and illustrate its use to model applications in an interoperable environment.<<ETX>>","PeriodicalId":270352,"journal":{"name":"[1993] Proceedings International Conference on Intelligent and Cooperative Information Systems","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123773471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All possible prototypical classes of (non-conflict) encounters are analyzed, and it is shown where the strategy and mechanisms result in stable and/or efficient solutions. In most cases, the negotiation strategy is both stable and efficient. These are two situations in which the strategy, in combination with both mechanisms, results in a conflict (a non-efficient result). The reason for this inefficiency may be the failure to include conflict-resolution techniques. It is conjectured that enhancing the mechanisms with such techniques would result in a stable and efficient outcome in those two situations as well.<<ETX>>","PeriodicalId":270352,"journal":{"name":"[1993] Proceedings International Conference on Intelligent and Cooperative Information Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124925459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presentation of the semantics is tailored to Epsilon, a management system for distributed knowledge bases whose modules may employ different logical systems, and that allows deductions to be performed interoperatively. The components of an Epsilon knowledge base are theories, and relationships like inheritance between theories are established via so called links. This paper gives a semantic foundation for Epsilon links, indicating the combination of information represented in different formalisms (using mixed institutions) as well as the constraining of the possible models of a theory to those freely generated by another one (using duplex institutions). These categorial concepts are applied to the actual implementation of Epsilon.<<ETX>>","PeriodicalId":270352,"journal":{"name":"[1993] Proceedings International Conference on Intelligent and Cooperative Information Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125107829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specifications extend agent architectures in a natural way so that the complexities found in distributed systems may be addressed. Such an approach has a number of advantages. It provides a general representation paradigm that can be used as a basis in a wide range of intelligent distributed systems, and is easily customized to cope with problems requiring graphs with differing structures and with different node and edge properties and attributes.

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.S. Rosenschein (1992) considered the first of these problems, namely how agents can maintain a certain amount of secrecy regarding their preferences, and still converge to a socially optimal choice. The authors address another of these Clarke Tax drawbacks, the need for a central vote-counting agent. They present several distributed voting schemes that do away with the need for a central vote counter. This improves the reliability of the system, and eliminates a potential system bottleneck. By distributing the vote counting, they also help maintain agent privacy-fewer agents need to know how an individual voted. They also consider how the Clarke Tax could be modified to give different agents different amounts of influence over the group decision.<<ETX>>","PeriodicalId":270352,"journal":{"name":"[1993] Proceedings International Conference on Intelligent and Cooperative Information Systems","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126586955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
