摘　　要：知识表示是知识工程的一个重要研究内容 ,是进行知识演绎的基础。知识表示有许多形式各异的方法 ,不同的表示方法都有其针对性和局限性 ,同一领域的知识也可采用不同的知识表示方式。简单介绍了知识表示的一般方法 ,并对它们的优缺点进行了综合的评价。同时举例说明了一些常用的表示方法的选择和应用。并进一步说明了知识集成表示的应用。Knowledge expression is an important researching content of knowledge engineering and a foundation for carrying out knowledge deduction. Knowledge expression has many methods of different forms, different expression methods all have their own aiming and limitation, and different knowledge expression mode can be adopted for knowledge of the same field. The general method of knowledge expression has been simply introduced, and a synthetic evaluation was carried out upon their strong and weak points. At the same time, the choice and application of some commonly used expression methods were illustrated by examples. And the application of integrated expression of knowledge was explained in further steps.
