Logic animation, a new style of animation, was first proposed in the application of dynamic geometry software. The concept, features, and possible application prospects of logic animation are further introduced in details in this paper, compared with the traditional style of animation-time-sequential animation. Based on the design ideas of dynamic geometry software, Flash and game engine, the design...
When the traditional text classification technologies classify academic dissertations, the dimension of extracted feature terms is high, and they can't represent the theme of thesis. it makes the efficiency is very low and the accuracy rate is not high. The topic words are small in quantity and can reflect the theme of thesis well. Accordingly, the paper proposes to extract the topic words with topic...
With the sudden growth of information technology, network resources and resource search technology have been developed rapidly. However, general search engines such as Google and Baidu are difficult to satisfy our retrieval requirements in professional field because the lack of professionalism. This paper constructs a vertical educational resource oriented search engine based on the circumstances...
The amount of digitally available informaition is growing at an exponential rate. Educational resource systems are in widespread use and knowledge develops and spreads rapidly in quality, quantity, profundity and extension. This paper describes a new model of knowledge element to organize knowledge and to share the educational resource, and presents the framework of a knowledge abstract and fusion...
The Sakai Community develops and distributes the open-source Sakai CLE, an enterprise-ready collaboration and courseware management platform that provides users with a suite of learning, portfolio, library and project tools. As an open source course management system, because of his open-source, as well as a powerful teaching function, Sakai has received the great success at the global level, and...
The educational information resource management system, which is based on SOA, achieves the goal of "change as need" for the system, ensures rapid update of the businesses and functions, improves the services of reuse, shortens the system development cycle, and cuts down the developed costs. This paper firstly analyzed the current educational resources management system, and found the existing...
By means of curriculum resources reuse and sharing mechanism, SCORM can shorten the time of resources development, lessen costs and implement free circulation of learning content among hetero-platforms. However, excessive curriculum resources for reuse cause the problems of synchronous updating and low efficiency in learning resource utilization. In this paper, we propose a Web services enhanced dynamic...
Knowledge develops and spreads rapidly in quality, quantity, profundity and extension. The key source of sustainable competitive advantage relies on the way to create, share, and utilize knowledge. This paper discusses the necessity of using knowledge elements for managing and representing knowledge, presents the framework of the main system, and describes the process of the knowledge elements mining...
The construction and effective application of net based educational resources are of great importance for e-learning. SOA (service oriented architecture) enables the reuse and share of net based educational resources by publishing the resources as web services. However, frequent identity authentications in resources access among different providers take up overfull system resources and lower the implementation...
In this paper, we propose a kind of dynamic expression of digital rights by rewriting license for digital rights management based on multiset rewriting and logic programming. Firstly, the essential elements definition is introduced. After that, the execution model is discussion. The final part explores the application model.
Organizations and communities are held together by knowledge flow networks whether people are aware of them or not. Knowledge flows influence the evolution of culture and language, promote international collaboration, and hasten the development of science. In this paper, we propose a Petri net based model of knowledge flow for more effective and efficient knowledge management, knowledge flow management,...
Because of its important application value in almost every region, early-warning has received extensive concern. This paper puts forward a study early-warning mechanism based on association rules. It uses an Apriori mining algorithm with some corresponding restrictions to dig out the latent school record association rules from former students' scores which are viewed as a history resource. Then these...
Metadata is the data that describes, locates and manages a specific resource object, whose discovering and obtaining is meanwhile facilitated. The application and popularization of metadata standard is propitious to the normalized description and sharing of resources. There are various metadata standards because of the diversity of resources and different demands of application, which hinders the...
Although the Digital Rights Management of Education Resources (ERDRM) has developed greatly these years, there are still many problems, such as the conflict of the rights-protected and the resources-shared, especially under the network environment. And by now there is still no good method to solve the problem. So in this thesis, we design a new system model, and introduce the performing flow of the...
With support of multiple learners and multiple roles in a learning activity, IMS Learning Design (LD) specification provides a collaborative scenario for participants. However, IMS LD provides insufficient support for interaction among learning activities and can not dynamically integrate learning resources to meet the continually changing service requirement. In this paper, we propose a BPEL-enhanced...
Web service is a new service-oriented computing paradigm which poses the unique security challenges due to its inherent heterogeneity and highly dynamic nature. A key challenge in Web service security is the design of effective access control schemas. However, traditional role-based access control (RBAC) model can not meet the dynamic and context sensitivity features of Web service demands. In this...
The paper studies the adaptive learning content organizing and difficult knowledge's diagnosis algorithm. At first, it discusses the granularity of learning resources, the adaptation of application environment, the evaluation of learning outcome and personalized choice of learning resources. Secondly, it designs learning content level framework, which takes knowledge point as the meaning unit. The...
The retrieval for educational course materials is mainly based on the keyword based match, educational course materials can not be achieved in a semantic way. The paper proposed the onto-query system, a specific semantic query system for educational domain. The paper first constructs the ontology for the instructional materials titled computer network and visualizes the representation of the ontology...
Service composition provides a flexible way to quickly enable new application functionalities in next generation networks. Composite services are turned to be more and more complex, and the performance analysis of composite service is an important issue for service providers who want to get better QoS. In this paper, we proposed a stochastic Petri net based approach for modeling Web service composition...
