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.
