2.2 Definition and Importance of Knowledge

Knowledge encompasses the implicit and explicit restrictions placed upon objects (entities),
operations, and relationships along with general and specific heuristics and inference procedures
involved in the situation being modeled.

Knowledge is to represent reality in thought or experience the way it really is on the basis of
adequate grounds. Knowledge is a description of the world. It determines a system’s competence
by what it knows.

Notes To know something is to think of or experience it as it really is on a solid basis of
evidence, experience, intuition and so forth. Little can be said in general about what
counts as “adequate grounds.” The best one can do is to start with specific cases of
knowledge and its absence in, say, art, chemistry, memory, scripture and logic, and
formulate helpful descriptions of “adequate grounds” accordingly.
