The relative ineffectiveness of information retrieval systems is largely caused by the inaccuracy with which a query formed by a few keywords models the actual user information need. With the help of the semantic web technology a significant step forward can be made in terms of a general description model for online laboratories and the location of laboratories with requested properties. In particular, engineering education is becoming an exciting emerging field of research because it involves a multitude of disciplines which aim to resolve the pedagogical problems that arise with the advancement of technology. Technology-enhanced learning is becoming a new important trend in higher education worldwide. Online laboratories are interactive experiments which are available over the Internet and can be divided into two main groups, software simulations and laboratories made up of real hardware equipment. Improved search mechanisms and facet based browsing are only some key features which enhance the data handling within the repository. The so called Web 3.0 technology is actually growing daily and is proposed to be one of the leading Web technologies within the next years. _log.This paper discusses the creation of a common framework to describe online laboratories according to the semantic web technology.

Of course the user is a member of the specified community.Īnother target is not to change liferay source code, just to override its default behavior. Our target is to redirect to a specified community page after a user login. I assume you installed liferay portal v5.2.3 Bundled with Tomcat 5.5 by this way.
