Fuzziness and context-awareness in decision-making schemas for semantic web

An introduction of the concept of Semantic Web has brought predictions, as well as promises of automatic finding and accessing information and services on the web. Uncertainty is an integral component of information and knowledge. Many concepts we deal with are without precise definitions, or with missing or inaccurate data. Such a situation is also present on the Internet where many sources of information could be corrupted, or partially and temporally inaccessible. However, uncertainty is not only associated with data and information stored on the web - also users cause ambiguity and imprecision. In many cases, users' decisions regarding selection of most suitable alternatives heavily depend on current circumstances, understanding of a situation, needs and requirements, as well as users' "mood" for selecting something new and/or unusual. All those aspects of a selection process are naturally ambiguous. In order to make the web a user-friendly environment where users can easily, quickly, and precisely find things they are looking for, new web utilization tools have to be developed.
