A well-established and widely accepted indicator for the quality of
scientific publications is the number of references to other
publications in the field. This number describes to which extent the
author has included related concepts in his work. A method like this,
which has already proved itself in reality, could be used in an online
environment such as the e-portfolio as well. It is possible that the quality of texts published in the internet is increasingly measured by its degree of relation to other content. In other words: In a hypertext environment, texts are considered to be of high quality if they show few redundancies to other content in the informationpool but a high degree of context relation (linkage, interconnection). In order to relate to other concepts, an informationpool containing concepts that have been agreed upon is needed. These concepts need to be available in a form suitable for hypertext. If it is easy to link an existing concept to others, students will handle tasks more efficiently.
