Knowledge theory and artificial intelligence

It is proved in the paper that it is knowledge that plays a crucial role for intelligence formation this is because of the fact that intelligence must normally be activated from knowledge and different categories of knowledge will thus lead to different categories of intelligence. On the other hand, knowledge itself should mainly come from information. Therefore, knowledge serves as a channel for linking information and intelligence. Without knowledge, information can hardly be transformed into intelligence. Even more interestingly, a unified theory of artificial intelligence can well be achieved if a comprehensive understanding of knowledge theory is reached.
