Recent advances in Web and information technologies have resulted in many e-learning resources. There is an emerging requirement to manage and reuse relevant resources together to achieve on-demand e-learning in the Web. Ontologies have become a key technology for enabling semantic-driven resource management. We argue that to meet the requirements of semantic-based resource management for Web-based...
Service discovery becomes a key to hastening the evolution of web services as the number of services is expected to increase dramatically. In this paper, we propose to index all the ontology-annotated outputs in registered services. For each ontology-annotated output, there is a service list which records all the services in the registry that deliver the output. Based on the indexing, we propose a...
Service discovery becomes a key to accelerating the evolution of Web services as the number of services is expected to increase dramatically. Foregoing work on service discovery is primarily based on the interfaces of services through the use of ontology. Ongoing work targets at service behavior, with not only individual message exchanges being captured, but also constraints between these message...
The existed methods of association rules retrieval have not given enough high-level semantic information retrieval support. In order to resolve this problem, the authors propose a new method of association rules retrieval that is based on ontology and semantic Web. Ontology-based association rules retrieval method can well deal with the problems of rule semantics sharing, rule semantics consistency...
Summary form only given. With increasing demands of effective and efficient transportation from our society, the transportation issue has become a noticeable obstacle to the economic development for all countries and regions to a great extend. ITS (intelligent transportation systems) technology is brought forward and considered as an effective approach that promises to alleviate many transportation...
In this paper, we present an architecture of ontology-based distributed simulation on grid (ODSG) which facilitates life-cycle management of large-scale distributed interactive simulation on the grid computing environment. The architecture aims at some further solved key technologies for M&S (model and simulation) and new simulation pattern on open, complex, large-scale distributed grid environment...
In order to meet the on-demand requirement of service composition at a large scale, one should go beyond the use of static domain ontologies but allow different focused aspects of the ontologies to be distributed as sub-ontologies. To demonstrate the feasibility of the sub-ontology idea, we suggest a possible implementation using the semantic Web technology and apply it to distributed e-learning
We study the problem of answering queries through a target RDF ontology, given a set of view-based mappings between one or more source relational schemas and this target ontology. We design a novel query rewriting algorithm that can efficiently rewrites a RDF query into relational queries using a set of RDF views. With our approach, we highlight the important role played by RDF blank node in representing...
