The target objective of this program is the harmonization of university level educational research, sociev practice and practical business. The Universitl). of Electro-Coniniunications has been appointed by Mombusho tojilfll some specijk parts of this program. In this paper we report our experience with the itittoduction of this progran4 its framework, settings, acnial iniplementatioti and preliniinaty jindings. 7be problem encountered are discussed together with U nunlber of soliitions to assist good practice in the building of such an applied eciucatiorlal program

By using it, it is possible to express the semantic features of the whole hyperspace and the states of exploratory activities in topological order. This approach is applied to generate the navigation information for the exploratory activity. The space explored is changed automatically by using the semantic similarities of the nodes which constitute that space. An extended self-organizing feature map is used as the semantic feature map of the hyperspace. This map is applied to express the user model and generate the navigation strategy for the user. The exploratory history of the user is mapped on it. Then, the semantic relations between nodes are shown on the map. The result reflects the exploratory state of the user, interpreted with the help of a user model.

The proper design is the first step towards common design patterns, leading to better, semantically enhanced authoring systems for AEH. This can mean easier access to these special tools for personalization for the domain expert without computer knowledge. A high-level taxonomy is proposed here, as a result of many brainstorming sessions within the European Community project, ADAPT. This taxonomy is justified with the help of both AEH implementations and theoretical frameworks.
