Summary: | Artifical intelligence or AI has come to its era of popularity since its introduction in 1930s.The era of AI started as the theoritical concept,later implemented in various applications. Initial research in AI concentrates on smulating human ability and thinking. In more advanced study of AI,the potential of human "technology" were further exploited. However, as human "technology" uses a large amount of knowledge (gathered from one's experience). Intelligent system could fail if knowledge provided to the system is insufficent. This paper discusses the important of knowledge in intelligent system development. Based on our research in developing intelligent systems, problems in gathering knowledge are addressed. Solutions for future research in this area proposed.
