Business applications create new demands to agent systems: Reliability and extensibility become new challenges beyond a general proof of concept. In this article we show how a combination of blackboard and agent techniques can help meeting these requirements: The COMRIS agent architecture uses an object oriented information system as shared blackboard for agents, simplifying agent communication...

Holoparadigm (Holo ) is a multiparadigm model oriented to development of paraUel and distributed programs. In this paper we proposc the Distributed Holo (DHolo ), a model to support the distributed execution of programs developed in Holo. DHolo is based on object mobility and blackboards. This distributed model can be fully implcmented on Java platform. Specifically, mobility is implemcnted usi...

The paper comprises an investigation, analysis and evaluation on using Blackboard as a digital repository for the course material of Control Engineering modules for Master degree at the University of Huddersfield. The advantages and limitations of using Blackboard as a digital repository for course materials and discussion board facilities are discussed. Also the use of action, quantitative and...

The present study investigates the central concerns of the use of visuals within the four EFL textbooks taught at Iranian high schools which have been prescribed by the Ministry of Education. To do this, the four EFL textbooks were evaluated and analyzed. Descriptive statistics were used to analyze data quantitatively. The analysis indicated that over the four textbooks, 95.71 percent of all vi...

Contemporary business applications often employ a process layer in order to coordinate automated activities. One option to build such a layer is to use a workflow management system. But the all-or-nothing fashion of such systems makes them sometimes hard to integrate. In such cases, custom development is an alternative. Yet concepts for the micro-architecture of process layers in business appli...

The purpose of this paper is to present two complementary patterns to build multi-expert systems, that is systems that need to integrate large, heterogeneous specialized modules, and implement complex, non deterministic control strategies. The rst pattern summarizes the blackboard pattern presented in [1]. The second pattern builds on the model of dynamic control where a blackboard system has a...

We propose an approach to service composition based on the ideas from Blackboard Systems extensively investigated in AI in 1970-80s. We combine these ideas with Onto⇔SOA – a SOA design framework that relies on a restricted document-oriented and ontology-based service model to provide guidelines for construction of services. The proposed Blackboard-style composition approach requires neither ext...

logical form or covert syntax is a syntactic level introduced in recent generative approaches. using the ideas of first-order predicate logic, it interprets the strings whose elements cannot move in s–structure, because an element moves if it does not acquire its necessary scope. but unlike the predicate logic, logical form is based on syntactic principles and rules. therefore, logical form is ...

Blackboard-based integration of multiple agents is a natural and viable technology for the implementation of concurrent-engineering (CE) environments. This article presents a blackboard architecture that has been extended to support the integration of heterogeneous collaborative agents. The suitability of the architecture as an integration framework for CE applications is discussed followed by ...

A prototype CAIS (cardiac arrhythmia interpretation syst/em) based on blackboard model is presented. The issue of automatic electrocardiogram analysis is addressed firstly. The idea ofbi-directional interaction is led into CAIS, which makes the system run in a kind ofway rather close to human mode of thinking. The process of PVC (premature ventricular contraction) diagnosis in CAIS is described...
