Methods and Tools for Acquiring and Presenting Information and

Aiming at a qualitatively new model of processing information in a heterogeneous environment such as the current and the future Web, it is desirable to focus among others on investigating new ways of working with information and knowledge in a heterogeneous environment, especially with imperfect and vague information from perhaps dubious sources. They should include acquiring information and knowledge, organising information and knowledge, including categorisation based on ontologies, presenting information and knowledge in a way appropriate for a human, verifying, measuring and determining quality of information and knowledge (relevancy and trustworthiness in particular), designing models, methods and techniques needed for an efficient processing of information and knowledge in an environment of heterogeneous sources. Research such as the outlined one should involve verification of results by means of extensive experimentation with one or several pilot applications in selected domains of application
