Research of the information space properties and its enhancement in order to allow an automated information processing (e.g., by recommending information and information space paths) represents an active research area at present. The contemporary Web has been designed to be browsed by a human. In order for a machine to be able to move effectively in the information space, the properties of the Web (as a network, but also as a storage of data, information, and knowledge) and the regularities of this network development must be better comprehended. Based on this, the network has to be enhanced with the structures expressing semantics which will enable an automated reasoning in this information space. At the same time, understanding the activities of a user working with information in the web and making use of the information acquired in order to achieve a more effective information providing and processing appears as a key issue.
The project aims at modeling the user and his activities in the Internet information space, and employing the models for the support of effectively making available information and its processing in the Internet. Modeling involves acquisition, processing, and employing knowledge about user activities in the Internet information space. We are developing software tools for the support of effectively operating the information.
Based on the aim of developing and evaluating a new model of the activities of a user working with the information from a specific problem area of research sources in form of scientific publication in the area of onformatics and information techniologies we focus on:
- support for a personalized navigation in large information spaces
- support for a visual analysis and navigation
- user ontology-based model development, employing semantics in reasoning aimed at information acquisition about the user, and enhancement of the existing information space according user interests, goals and preferences
- employing the common interests of the users and their collaboration in acquiring the information from the Internet.
We use the World Wide Web service as an environment suitable for the research of models of user activities in the Internet information space. Experiments are performed on ontology-based information space developed for testing that contains thousands instances of scientific publications (journals and proceedings) from the field of informatics and information technologies.
