Context-aware computing is one of the key issues in virtual computing environment. This paper aims to compare the ontology-based context modeling and reasoning approach with the traditional non-semantic one. A general scenario of virtual computing is given about the dynamical service aggregation and evolution. And the context of the environment is modeled respectively using an OWL based way and a...
This paper, remote education learning resource for metadata standards that learning resources in the semantic status of the missing, to analyze learning resource metadata,as well as learning resource metadata and ontology integration, combining meta-data ontology with domain ontology to form a learning resource ontology, instantiating the metadata ontology and domain ontology, using IEEE LOM metadata...
Nowadays, with the appearance of more and more web services, it has been one of the key points that how to find the target service quickly and precisely. Traditional methods of web service discovery are only based on the keyword matching, but it's very difficult to realize more detailed and intelligent services, and the results are hardly to meet the user's demands. According to the current OWL-S,...
In this paper, we propose a better solution to the limitations involved by using the current standard of syntactic matching for resource discovery in Grid environment. Our observations noted that syntactic matching was limited in its ability to use all available resources. In order to overcome these limitations, we hereby propose a method for resource discovery involving semantic matching based in...
The objective of knowledge processing system is to promote knowledge integration, sharing and retrieval in distributed and heterogeneous environment. This paper puts forward an ontology-based model-OBKPM for knowledge processing, which promises better access to relevant knowledge by producing a global domain ontology that is used for establishing semantic connections among the local ontologies of...
In order to build an open, collaborative and efficient visual group learning system (VGLS for short below) in a wide area network (WAN for short below)environment, such as the Internet, this paper studies how to combine multiple techniques such as the mobile agent, ontology and Web services composition to build a VGLS. As the research result, a distributed model for VGLS (DM4VGLS for short below)...
Organization technology of education resource has a close relationship with the realization of sharing, reusing, meaning-based indexing of it. This paper introduces basic knowledge about ontology, concrete application of ontology in the field of knowledge management. Discuss the critical factors of education resource in the view of ontology. Then put forward an ontology model of education resource...
Knowledge representation is a multidisciplinary subject that needs to apply theories and techniques from logic, ontology and computation. There are a great number of languages able to represent knowledge, among them UML can be considered a suitable language for modelling knowledge. It could be included within the category of visual languages for knowledge representation. On the other hand, numerous...
SBVR is a new standard that defines a metamodel for business-layer vocabularies and rules. This paper summarizes SBVR features and argues that the SBVR enables definition of true ontologies. The paper also summarizes experience with a partial SBVR implementation in the context of an existing technique for modeling businesses and transforming the models into implementations. The work contributes to...
