Bayesian network is an effective tool to represent the probabilistic relationships among variables and do probabilistic inference. The algorithms of both network training and reasoning are complex and diverse. There exists no algorithm appropriate to all kinds of dataset, so it is improper to deploy all the algorithms of Bayesian network on one server especially when providing service in a distributed...
Service oriented computing is a computing paradigm that utilizes existing services as the basic construct to compose new service / application, with service oriented architecture (SOA) as its architectural concept. A service architecture that is capable of changing its structure and functionality autonomously with little human intervention is required to address the issue of complexity and dynamism...
Based on the model of Ningxia public commercial information service platform for SOA, this paper proposes architecture of multi-agent system (MAS) of public commercial information service platform. In the MAS of this architecture, the human-computer agent, the service agent, the service bus agent and the interface agent correspond to the interactive service layer, the application service layer, the...
An effective software design should ensure that all the quality requirements of a system of interest are supported. As the architecture of a software system can be seen as a set of architectural design decisions (ADDs), the identification of design issues and the choice of design alternatives heavily impact the quality of software systems. This is especially challenging in service orientation for...
In order to preserve the contents of "funeral dance" effectively, this paper designs a simple and rational knowledge representation approach which constructs the semantic Web architecture based on CIDOC CRM, and then uses inference engine to verify its legality. Application has proved that it is feasible and effective and can facilitate the knowledge share and reuse in ethnic dances filed.
This paper charts the course of adaptive behavior in intrusion tolerance, starting from pre-programmed and user-controlled reactive adaptation to highly sophisticated autonomic and cognitively driven adaptation. The goal of intrusion-tolerance is to provide mission continuity even under conditions of sustained cyber attacks. We describe key themes of our previous work in adaptive cyber defense and...
A variety of frameworks, architectures and techniques have been proposed and used in the field of autonomic computing for self-management. There are also many applications and systems available that exhibit autonomic behavior. However all techniques and applications do not explicitly use autonomic or self-* terminologies to describe their autonomic characteristics. In this survey paper, a review of...
This paper proposes a utility computing model that allows environment aware dynamic service discovery, orchestration and deployment. The model enhances previous Service Oriented Architecture (SOA) in that it is based on the new conception of environment aware agile service utilities. We introduce the concept and discuss its research issues upon which a novel approach is conceived. We elaborate the...
In this paper we propose a way to facilitate the issue of discovering the eGovernment services that address a citizen's need. This approach is implemented in an application, which we call a semantic portal. The semantic portal is part of our SemanticGov project architecture. The portal's components and its architecture are presented and explained. The portal's conceptual modeling is based on the generic...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
