also very difficult to automatically understand even stories written for little
children.
Some essential theories of AI still need improvements. No breakthrough
progresses have been made for some key technologies such as Machine Learning,
Non-monotonic Reasoning, Common Sense Knowledge Representation and
Uncertain Reasoning. It is also very difficult for global judgment, fuzzy
information processing, multi-granular visual information processing, etc
Conclusively, AI research is still in the first stage of Intelligence Science, an
indispensable cross discipline which dedicates to joint research on basic theories
and technologies of intelligence by Brain Science, Cognitive Science, Artificial
Intelligence and others. Brain Science explores the essence of brain and
investigates the principles and models of natural intelligence in molecular,
cellular and behavioral level. Cognitive Science studies human mental activities,
such as perception, learning, memory, thinking and consciousness. AI research
aims at imitating, extending and augmenting human intelligence through artificial
means and techniques, and finally achieving machine intelligence. These three
disciplines work together to explore new concepts, new theories and new
methodologies for Intelligence Science, opening up prospects for a successful
and brilliant future in the 21st century (Shi, 2006a).
1.2 Cognitive Issues of AI
Cognition is generally referred to as the process of knowing or understanding
relative to affection, motivation or volition. Definitions of cognition can be
briefly summarized into 5 main categorizes according to American psychologist
Houston etc:
(1) Cognition is the process of information processing;
(2) Cognition involves symbol processing in psychology;
(3) Cognition deals with problem solving;
(4) Cognition studies mind and intelligence;
(5) Cognition consists of a series of activities, such as perception, memory,
thinking, judgment, reasoning, problem solving, learning, imagination,
concept forming, language using, etc.
