We present a methodology and database mediator tool for integrating modern knowledge-based systems, such as the Stanford EON architecture for automated guideline-based decision-support, with legacy databases, such as the Veterans Health Information Systems & Technology Architecture (VISTA) systems, which are used nation-wide. Specifically, we discuss designs for database integration in ATHENA, ...

This paper introduces a novel wrapper-mediator based semantic data grid service mechanism to solve the problem of Semantic heterogeneity and few compatible data sources. It uses ontology based semantic information to wrap the heterogeneous data source, and employs mediator structure to supply accessing interface for the data sources, and it extends semantic query, mapping and fusion languages t...

Partner Relationship Management Systems are implemented in many companies to improve the relations to important partners along the value-chain. The goal is to differentiate themselves from competitors and their products. That leads to different types of relationships between customers, suppliers and other market-participants. Some of these types require a mediator, that connects the partners, i...

Ontologies are built to provide semantics to real world terms. This obviously creates multiple representation of the same term by different societies. Such diversified views necessitate the need for some kind of mediator, which facilitates sharing of knowledge that can be used for effective communication of the meaning. Ontology Mapper is a MAS that provides mapping service to department agents...

In this article we present the use the knowledge for a Mediation System, developed to give support to mechanical system designer activities. The use of cooperative systems must contain a sufficient level of assistance to facilitate and coordinate the actor’s activities. To accomplish this goal we introduce an artificial actor: the Mediator. To illustrate our approach we will present the specifi...
