Mediators are a critical component of any data warehouse; they transform data from source formats to the warehouse representation while resolving semantic and syntactic conflicts. The close relationship between mediators and databases requires a mediator to be updated whenever an associated schema is modified. Failure to quickly perform these updates significantly reduces the reliability of the...

Past research has examined the contribution of mediator-based encoding strategies (interactive imagery and sentence generation) to individual (particularly age-related) differences in associative memory exclusively in the paired-associates paradigm. In the present study, we examined young and older adults' mediator-based strategy use on source-monitoring tasks. Participants spontaneously used m...

Microbial fuel cells (MFCs) are processes used for simultanuous bioenergy capturing and waste treatment. In this study, a model for MFCs based upon a conduction mechanism for electron transfer is proposed, which integrates substrate utilization, current production and conduction and  microbial distribution and growth in batch flow mode. The outputs of the model and that of a mediator based mode...

In this paper we introduce a negotiation mediator in a multiagent context. When negotiation fails, a mediator can interact with the parties, find out about their goals, ontologies, and arguments for and against negotiation outcome, and suggest solutions based on previous experience. An algorithmic schema to be instantiated with particular argumentation, semantic alignment and case-base reasonin...

background: protein-protein interactions do not provide any direct information re­garding the domains within the proteins that mediate the interactions. the majority of proteins are multi domain proteins and the interaction between them is often defined by the pairs of their domains. most of the former studies focus only on interacting do­main pairs. however they do not consider the interaction...

Many users and applications require the integration of semistructured data from autonomous, heterogeneous Web sources. Over the last years mediator systems have emerged that use domain knowledge to overcome the problem of structural heterogeneity. However, many users of these systems do not have a thorough knowledge of the complex global schemas and of the comprehensive query languages. Consequ...

This paper descripbes an open, flexible infrastructure to support virtual organisations using mediator agents. When applied in businessto-business electronic commerce, the mediators allows partners to exchange rich business information, and act in an agile and coordinated manner. As an example, we have created a demonstration application in the domain of telecommunications service provision, in...

In this paper we focus on the construction of a declarative mediator language. The language provides the ability to handle multiple logic theories, extended with program expressions. Two motivating examples are presented. The denotational and operational semantics of the language are introduced and a bottom-up e cient implementation is de ned and proved correct with respect to the given semantics.

MIWeb realizes a mediator-based integration of heterogeneous metadata sources over the Web. Mediators are well known from database integration. They improve the quality of search results by providing a query language, by automatically coupling sources, and by filtering redundant results. The MIWeb system contributes mediator architectures in the context of Web sources, metadata standards for in...
