INTRODUCTION Amount of accessible information and knowledge grows at an unprecedented pace. 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. 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. A robustrelative importance index definition is the final step to obtain a ranked importance concept listthat will be helpful both to measure trends and to find a quick path to the most appropriatepaper in each case.Īiming 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. As most retrievingand information extraction algorithms require manual training, supervision, and tuning, itcould be shorter and more efficient to do it by hand and dedicate time and effort to perform aneffective semantic search list definition that is the key to obtain the desired results. Thosedatabases usually contain a few hundred documents, information requirements are distinct ineach research project, and technique algorithms are not always the answer. Researchers do need to extract specific information from theirscholarly document databases depending on their predefined breakdown structure. Extracting knowledge from big document databases has long been a challenge.Most researchers do a literature review and manage their document databases with tools thatjust provide a bibliography and when retrieving information (a list of concepts and ideas), thereis a severe lack of functionality.
