26 Soft Computing and Its Applications
niques for uncertainty representation and processing to the forefront of semantic
web research. In the last few years, a number of seminal workshops and seminars
have spread the interest for these issues within both the Semantic Web and the
fuzzy logic or soft computing communities. Fuzzy logic has been used to bridge
the gap among intuitive knowledge and machine-readable knowledge systems.
Much research is also being done on techniques for extracting incomplete, partial
or uncertain knowledge, as well as on handling uncertainty when representing
extracted information using ontologies for example, to achieve semantic interoper-
ability among heterogeneous systems. Semantic Web demands the management
