（重定向自Certainty factor）
专家系统是早期人工智能的一个重要分支，它可以看作是一类具有专门知识和经验的计算机智能进程系统，一般采用人工智能中的知识表示和知识推理技术来模拟通常由领域专家才能解决的复杂问题。
一般来说，专家系统=知识库+推理机，因此专家系统也被称为基于知识的系统。一个专家系统必须具备三要素：
- 领域专家级知识
- 模拟专家思维
- 达到专家级的水平

In artificial intelligence, an expert system is a computer system that emulates the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning about knowledge, represented primarily as if–then rules rather than through conventional procedural code. The first expert systems were created in the 1970s and then proliferated in the 1980s. Expert systems were among the first truly successful forms of AI software.
