TAILIEUCHUNG - Lecture Notes in Computer Science- P96

Lecture Notes in Computer Science- P96:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers | 464 W. Tian and Y. Mao database resource panel the upper-left part of to view the table and column definition of the relational database and use the ontology browsing panel the low-left part of to browse the RDF ontology graphically. The user can then specify which RDF class and which RDF property one table column should be mapped onto. After finishing the mapping the tool automatically generates a registration entry in RDF XML format and submits it to the semantic registration service. For example a teacher wants to register courseware recourses. The Semantic Registration tool directly registers courseware resources to the Semantic Registration Center. It is a semantic mapping from the local courseware resources to the sharing semantic ontology. During the registration mapping information is written into a semantic registry. The courseware resource content itself is not uploaded to the registration center or any other centralized node. When the user searches resources the Semantic Registration Center will look up the result from the resource registration table. User will download and browse the corresponding resources from the data node by linking it directly. The way it works is very similar to other P2P mode. Fig. 5. Semantic Registration Tool For E-learning Semantic Grid 5 Related Work There are a lot of relevant works. Within the domain of Grid research there are many efforts about accessing and integrating e-learning database under the grid framework. A Semantic Grid Application for E-Learning Data Sharing 465 Typical example is Realcourse 2 . Realcourse is a successful application of distributed computing 13 technology in a geographically wide area. Different from some traditional distributed fault-tolerant services like ISIS 14 Realcourse emphasizes giving clientsÊ access to the service with reasonable response time. For most cases it means as much of the time as possible. In 12 it is clear that standards like LOM or Dublin Core are gaining .
