Lay Summary (English)

Lead
Lay summary
Today's Web search engines are mostly limited to keyword search and by now there is no engine capable of understanding and processing natural language or at least suggest users related linguistic terms during search. Through recently evolution in social Web technologies in respect of easy to handle tools on the other side, more and more users bustle in today's Social Web. Most of these users are not or only limitedly able to word their search needs through precise queries to exert Semantic Web full potential for example.

Classical logical systems such as propositional logic, predicate logic and modal logic, as well as AI-based techniques for natural language processing and knowledge representation, interaction, and reasoning are concerned in a fundamental way with propositions expressed in a natural language. Unlike classical logical approach, soft computing is among other things based on fuzzy logic and provides an expressive language for knowledge representation, interaction, and reasoning. Fuzzy logic provides a mathematical power for the emulation of the higher order cognitive functions, the thought and perception. Considering that the fuzziness is ubiquitous and essential for the human beings, fuzzy systems offers new perspectives for improving the human-machine interactions.

The proposed approach attempts to establish new interactive knowledge representation and reasoning techniques. For example, visualized interactive maps such as topic maps, cognitive maps, mind maps, etc. can help to find similar linguistic terms clustered around a topic. The inclusion of soft computing techniques to knowledge representation, interaction, and reasoning offers new ways for human-computer interaction that are not yet explored, as for example paraconsistent reasoning. In addition, a representation as map has the advantage that humans can interact with such a system in a natural way. The interactive visualization of these maps is a first step solely established for augmented user understanding but in future these maps ought to be enhanced to knowledge bases for machines to reason on users' vague natural language expressions too.

Following a design science research approach, several research methods will be applied during the post-doc research stay: literature review, argumentative-deductive analysis, grounded theory, structured interviews and case studies, test installations, and controlled experiments. Based on simulations with a prototype the differences, advantages and problems of approximate reasoning in the Social Semantic Web should be determined.
