Bartenstein, Oskar; Geske, Ulrich; Hannebauer, Markus and Yoshie, Osamu. Web knowledge management and decision support : 14th International Conference on Applications of Prolog, INAP 2001, Tokyo, Japan, October 20-22, 2001 : revised papers, p.67-69
Most human knowledge is not well-structured for formal representation and machine processing. Even worse, some of this knowledge is not easily accessible through experts and it can be distributed in a huge information space such as the World Wide Web. Providing appropriate access to such heterogeneous knowledge sources is important for building knowledge-based information systems. There is an urgent need for complementary tools and techniques that derive formal knowledge structures from informal information so that inferences can be made automatically.
