Experimental Adaptive Web Portal with Semantic Data Store

Nowadays, the web is a widely used source of information. Therefore, current research is focusing on making the information retrieval more effective. Adaptive web technologies enable the storage of information about users and adapt the content of documents to user preferences. In our research, we are developing a general model of adaptive system. For evaluation of our theoretical results we have developed a prototype of an adaptive system and performed several experiments. In this paper we will describe important characteristics of the prototype system architecture, relations with our adaptive system model, performed experiments and proposals for future extensions.
