The huge amount of heterogeneous material data on the Web makes it increasingly difficult for users and computer applications to find and access required information because their semantics are not understandable by machines. Integrating such heterogeneous material data sources is a critical issue for the material scientific community. A lot of data integration initiatives have been implemented. But...
Thesauri are concept schemes that help in efficiently characterizing and retrieving items from digital libraries. SKOS is a data model that provides a standardized way to represent thesauri-and controlled vocabularies in general-using Resource Description Framework. A digital repository system that can inherently ingest and handle thesauri, although not in SKOS format, is DSpace. SKOS support in DSpace...

In this paper, the student model of adaptive learning system based on semantic Web has been established,which is based on theories such as cognition psychology, construction principle, humanism and utilizing ASP.NET, SQL server, data mining technology and the semantic Web excavation technology. This model mainly considers three factors including user study style, cognition level, interest and hobby...
This tutorial explains and describes the use of several microformats, which make information marked up in HTML available for use in applications outside traditional Web browsers. Because microformats consist of minor additions to the HTML backbone of common Web pages, they represent a simple but significant move toward what Tim Berners-Lee has called the ldquosemantic Webrdquo-but without requiring...
The following topics are dealt with: database; expert system; text-based information retrieval; data management; virtual engineering; multimedia data mining; multimodal information content; Web semantics; XML; secure system methodology; global data repositories; mobile P2P; computer user behavior; information system; evolutionary techniques; information extraction; media production; e-learning system;...
The increasing number of available resources that may be used during e-learning scenarios can show problems of access, management and sharing of these resources. An e-learning application deals with the same problem of relevance to the Web. The semantic Web recommends standards for providing a solution to these issues. One main feature of this new Web generation is the use of semantics based on ontologies...
In this paper, we provide an overview of the overall process of authoring of educational resources in a semantic Web application that we are developing about adaptive hints in assessments. In this framework, we present some examples of semantic Web annotations about course topics, exercises and hints in notation 3 (N3). The current different roles and actions for the authoring process are explained,...
The last couple of years have shown that eLearning is not accomplished by simply providing pdf or ppt files on the Internet. Learning concepts have to tie in with technical implementations so as to generate the added value that will lead students to actually make use of the advantages of digital learning. The contents of such a system must not be isolated but should draw connections to a variety of...
With the invention and growth of the Internet web-based tutoring systems are now more popular than ever. Although being widely available and easy to use, their role in the process of education is often limited due to the lack of interaction between the machine and the student. ICT, interactive web-based C tutor, being developed at the Technical University of Lodz, Poland, is an attempt to create a...
