Artificial intelligence (AI) ,an interdisciplinary field, is usually regarded as a branch of computer science, dealing with models and systems for the performance of functions generally associated with human intelligence, such as (71) and learning.
In AI, knowledge-based system is an information (72) system that provides for solving problems in a particular domain or application area by drawing inferences from a knowledge base. Moreover, some knowledge-based systems have learning capabilities.
Expert system (ES) indicates the knowledge-based system that provides for solving problems in a particular domain or application area by drawing inferences from a knowledge base developed from human (73) . Some expert systems are able to (74) their knowledge base and develop new inference rules based on their experience with previous problems. The term "expert system" is sometimes used (75) with "knowledge-based system", but should be taken to emphasize expert knowledge.

人工智能(AI)这一交叉领域，通常视为计算机科学的一个分支，研究用于表现与人类智能有普遍关联的各种功能(例如推理和学习)的模型和系统。
在人工智能中，基于知识的系统是指一种信息处理系统，用于从某一知识库作出推断，以此解决特定领域或应用方面的问题。此外，某些基于知识的系统具有学习能力。
专家系统则指一种基于知识的系统，通过从人类专家经验开发出来的知识库进行推断，以此解决某一特定领域或应用方面的问题。某些专家系统能根据以前解决问题的经验，改进其知识库并制定新的推断规则。术语“专家系统”有时用作“基于知识的系统”的同义语，只不过前者强调专家的知识。
