摘　　要：在本文中,我们提出了利用面向对象的技术表示语义和常识的方法。将知网中的义原(即最小的语义单位)表示为类,同时将概念之间、属性之间的语义关系转换为类之间关系以及类的属性之间的关系;将知网概念词典中的概念表示为所在范畴属性类的子类,并将DEF项中其它义原设置为该类中的变量。通过这种转换,知网中的语义和常识就被表示为类和对象。在实践中表明该方法是实际可行的,更重要的是为我们今后进行从文本中提取知识的研究打下基础。In this paper, we suggest a method of representing semantic and common knowledge by oriented-object technology. The smemes in HowNet, which are the smallest meaning units, are represented by classes, then transform inter-concept semantic relations and the inter-attribute semantic relations into inter-classes relations and inter-attribute of classes relations; concept meaning in the HowNet's dictionary represents a subclass of categorical attribute class, the other sememes in the DEF item of the concept keep in the variables of the class. After processing, the semantic and common knowledge are represented by classes and objects. These show our method is practically feasible, and these results are critical bases of further researches of representing knowledge acquired from text.
