At the basis of the Activity-based Cost Management, the Cost Design and the traditional Standard Cost Management, the Enterprise Total Cost Management Model is put forth, which orients the Product overall Lifecycle Management and includes the all the business activities of the enterprise entire supply chain, to improve the veracity of cost computing. ETCMM, which advises the Target Cost to design...
Computing resources of both hardware and software tends to be located at a certain place. Computing Grid that supports necessary application and required computing power offers the computing resources anywhere, if there is an Internet connection. A simple model of computing Grid composed of computing sites is designed with a new representative of the Grid, coordinator. It consolidates the computing...
The collaborative distant learning environment has an extensive application prospect in modern computer supported network education. This paper presents a framework of constructing the distance collaborative learning environment with the virtual network computing technology. The cooperative participators use the VNC virtual desktop to share the same teaching program and cooperate in the common education...
As the technology of Web Services developed, consumers do not only focus on the function of the services, but also pay attention to non-function quality (reliability, availability, request-to-response time etc). We will introduce three services scheduling algorithm: First-Come, First-Serviced Scheduling, Shortest-Job First Scheduling, and Priority Scheduling. Then we-ll give an example of matrix calculus.
We present a general framework intended to support automatic service discovery and monitoring in the WSResource Framework (WSRF). The framework describes the metadata of WS-Resources using ontology and provides an efficient mechanism to aggregate and maintain the ontology instances. The mechanism utilizes the constructs and message exchanges defined by the WSRF specifications so that it is applicable...
Component adaptation is widely recognized to be a crucial problem. Components that partially satisfy the constraints of a design problem are adapted using different adaptation methods and adaptation architecture. In this paper, we describe the component and component adaptation in formal specification and present several adaptation types, then present an overview of the component adaptation methodology...
This paper introduces a method for automatic composition of Semantic Web services. First, according to OWL-S ServiceProfile, we define formal Web service model for meaningful matchmaking through the use of composition rules. These rules compare the syntactic and semantic features of Web services to determine whether two services are composable. Then, Petri net is used to model for composite service...
For supporting Grid application to be executed availably in Grid resources, the scheduler should allocate the most suited resources to the application. To address such problem, we need evaluate the grid resources in trust, reputation and performance etc. In this paper, a trust and reputation model for protecting the benefit of grid user is introduced. The trust and reputation is dynamically judged...
Simulation grid (SimGrid) is fit for evaluation of warfare performance. Since stakeholders in warfare simulation include scenario developers, running&managing personnel and model managers, it firstly analyzed what the stakeholders would expect from SimGrid. Secondly presents a special SimGrid architecture which could be divided into three levels: application level, HLA/RTI(High Level Architecture...
Web services and Grid computing are technologies with a great impact these days. Both technologies are taking a syntactical based approach to describe services, and therefore, limited support is provided for service related tasks like: discovery, composition, etc. Semantic Web services try to overcome the limitations of syntactical based approaches by adding semantics to services descriptions. One...
There are many problems in the Web ontology extracting and processing, such as the ununified ontology languages, lacking of tools, and limited the tool-s plain functioned methods. To solve these problems, here we reported a new method which neglects the grammar difference of the existing ontology language and puts forward a Jena based Web page ontology extracting and processing method on the common...
Fuzzy cognitive maps (FCMs) can represent and reason causal knowledge with stronger semantics. And the causal knowledge widely exists in knowledge grid. To provide information services with stronger semantics in Knowledge Grid, we need to know the reasoning mechanism and the characteristics of FCMs. In this paper, we have proved that the reasoning process of FCMs is a discrete topological semi- dynamic...
This paper presents a framework for agent-enabled semantic integration in the design of distributed digital museum. In this framework, Web Services provides remote information process services which can be discovered and invoked by middle-layer agent to satisfy multiple needs. Domain Ontology is used to characterize and model the semantics that are embedded in the digital museum. Concept-mapping Agent...
Semantic Web recommender systems is more complex than traditional recommender system in that it raises many new issues such as user profiling, navigation pattern. Semantic Web based recommender service aims at combining the two fast- developing research areas Semantic Web and User XQuery. Nevertheless, as the number of web pages increases rapidity, the problem of the information overload becomes increasingly...
Semantic Web Services (SWS) intend to enhance interoperability and encapsulate domain knowledge via semantic descriptions. This paper claims that service composition in a service-oriented computing paradigm is an AI planning problem. We present the Event Calculus (EC) - a well-known action theory, and further discuss the mechanisms of using the formalism for representing and reasoning service capabilities...
This paper presents a mechanism considering both browse and query for semantic information portals to retrieve information based on Knowledge Base. Our browse mechanism utilizes ontology query languages to let users browse freely, and a graphical query interface is proposed to facilitate users formulating ontology based query.
In this paper, evaluation on 7 RDF storage systems with respect to the large data applications is presented. By using the toolkit LUBM-R, 4 different scales of RDF datasets to proceed with benchmark are gotten. The target systems which are evaluated includes two storage systems based on memory (Sesame-Memory and Jena-Memory), two persistent storage systems with RDBMS underlying (Sesame-DB and Jena-DB),...
An ontology-based framework of B2B integration is presented in this paper. The backbone of the framework is a central Integration Intermediary, which provides common ontology modules for registered companies to reuse. Due to the reusing, the developing of a company-specific ontology is simplified and the similarity between different ontologies is improved. The mapping between different companies-...
Web prefetching is one of the effective solutions to reducing the user perceived latency, but if not properly managed, it may consume too much network bandwidth and system resources. The side effect can partly be avoided by prefetching control. Because existing cache occupants may have to be ejected to give room for the prefetched items, the cache hit ratio is not only affected by the remained cache...
In this paper, two cache replacement algorithms are presented. One is based on association rules, in which we extend the LRU replacement algorithm by making it sensible to Web access models extracted from Web log data using Web mining techniques. The other one is based on Markov models, in which we improve the LRU replacement algorithm by applying Markov models.
