Semantic similarity measure plays an important role in semantic search. However, Intention in educational resources search with semantic similarity has been rarely. In this paper, we proposed ontology based semantic similarity method to compute the user query and provided educational resources, so as to improve the search efficiency. A prototype system has been implemented in light of this approach...
Metadata is data about describing a concrete resource object and can carry on the localization, manage and its discovery and the data gaining is helpful also. OAI-PMH (Open Archives Initiative-Protocol for Metadata Harvesting) is a protocol universally proposed to settle interoperation of metadata. Metadata and OAI based information retrieval model can not only collect the DC (Dublin Core) metadata...
Design and application of learning activity is an important content in e-learning. The paper firstly analyzes the state of art in designing learning activities, including simple sequence specification, educational markup language, learning design theory and so on. In aspect of the compounding application between learning activities and learning resources, the paper discusses the basic designing strategy...
With the rapid development of information technology, educational resource systems are in widespread use. For the reuse and sharing of resources and function modules, this paper designs the framework of a SOA-Based Educational Resource Services System, and presents its implementation. Besides the common characteristics of SOA, the system is flexible and scalable.
Development of educational ontologies is a step towards creation of sharable and reusable adaptive educational systems. Concept maps are graphical tools for organizing and representing knowledge, it can be used in ontology-building, and can also be used flexibly to represent and shareable idea. This paper introduces the stepwise of designing the educational ontology of Computer Networks (CN), and...
There are many different e-learning system and educational resources, which have cause the problems, such as standard was not unified, resources was difficult to be shared, the supporting service need to be improved. The paper proposed an Educational Resources Public Service Platform based on Heterogeneous Data Exchange (ERPSP). ERPSP is an E-learning Resources Platform integrates all levels of educational...
To build a web-based virtual learning environment depends on information technologies, concerns technology supporting learning methods and theories. A web-based virtual online classroom is designed and developed based on learning theories and streaming media technologies. And it is composed of two parts: instructional communicating environment (ICE) and collaborative learning environment (CLE). ICE...
The semantic Web constitutes an environment in which human and machine agents will communicate on a semantic basis. It appears as a promising technology for implementing e-learning. In this paper we have described an approach to bring knowledge service to the semantic web for the area of education and learning. We have shown how knowledge service functionalities can be embedded into semantic Web services,...
In this paper, we proposed the learning resource ontology(LRO) models to formally describe learning content and learning context, respectively. In addition to utilizing the models to formally describe content, we also derived ontological relation between the content and context at semantic level. Furthermore, we have built a semantic similarity algorithm to measure the similarity between ontologies...

The rapid increase of e-learning resource makes it difficult to make, find access and reuse useful resource. To solve the problem, we develop a standardized content service system (SCSS) for distributed learning resource. The system is based on J2EE technology and Web services. It can provide the service for the conversion of non-standard resource and the development of standard resource. It also...
The new crop of learning content management system (LCMS), designed to create, store, assemble and deliver personalized e-learning content at the object level, are likely the closest application yet to bridging knowledge management and learning management. Selecting and implementing a LCMS will be one of the largest IT projects tackled by many organizations. With so many vendors and products, it is...
Although the online network educational system provides lots of learning resources, its application is limited for personalized service. How to satisfy the learners with their personalized needs, initializing student model is the research's primary problem of e-learning. We introduce a framework of initializing student model which aims at the personalized information of learner and evaluation strategies...
