The eClass is an instrumented environment that automatically captures details of a lecture experience and provides effective multimedia-enhanced webbased interfaces for users to review the lecture. The CoWeb is a web-based service for collaborative authoring of web-based material. The eClass and CoWeb information repositories, when integrated, provide a persistent medium for collaborative learn...

This paper discusses experience and technical issues in teaching a virtual course in the IT area which integrates lecture, tutorial and laboratory material. The lectures are based on multimedia material consisting of Web documents complemented with audio material allowing students to attend virtual lectures online. An integrated Web-based tutorial and lab service provides a dynamic illustration...

In this paper, we address the problem of web-domain POS tagging using a twophase approach. The first phase learns representations that capture regularities underlying web text. The representation is integrated as features into a neural network that serves as a scorer for an easy-first POS tagger. Parameters of the neural network are trained using guided learning in the second phase. Experiment ...

In this paper, we describe representations and inference techniques that are used in the RoboEarth system for the web-based exchange of information between robots. We present novel representations for environment maps that combine expressive semantic environment models with techniques for selecting suitable maps from the web-based RoboEarth knowledge base. We further propose techniques for impr...

The introduction of the new technologies of computer networks and hypermedia systems in education seems promising. However, only through experimentation can the effectiveness of these technologies be demonstrated. This was the main objective of the EONT project, in the process of which the National Technical University of Athens adapted an introductory course in Software Engineering to a novel ...

User-adaptive systems for the Semantic Web need approaches for user modeling that work, unlike traditional approaches, under the open-world assumption. A novel framework for eliciting a user’s conceptualization based on an ontology-driven dialog is presented here. It has been integrated in an RDF/OWL-based adaptive semantic-web software architecture for learning content management. We illustrat...

This work proposes p-Learning grid, a service-oriented approach, based on a pervasive learning grid, for solving difficulties associated with the sharing of learning resources distributed on different e-Learning platforms. The p-Learning grid not only enables collaboration and effective reuse of learning objects but also supports learning anytime, anywhere. Since the WSDL of web services remain...

Unity: Unity is a widely-used cross-platform game develop system. It consists of a game engine and an integrated development environment (IDE). It can be used to develop games for many different platforms, including PCs, consoles, mobile devices, and deployment on the Web. In this lecture, we will present the basic elements of Unity. However, this is a complex system, and we will not have time ...

In higher education research, computer and information technologies are getting increased consideration and attention. These technologies can be integrated into the design education through taking into account a scaffolding mechanism, which will support activities of teaching/learning in a distributed environment. This research presents a digital-based scaffolding geographic information systems...
