面向对象数据库中的模糊类层次建模

本文提出了一种建立面向对象数据库中模糊类层次模型的方法，利用属性与类的相关和对象与类间的语义距离与建立对象与类的关系；利用属性与类的相关和类与子类间的语义距离来建立类与子类的关系。同时，讨论了模糊类层次中多重继承的问题，这种模型扩充了现有的面向对象数据模型，并与其兼容。

FUZZY CLASS HIERARCHY MODELLING IN OBJECT-ORIENTED DATABASE

This paper presents an approach to establishing fuzzy class hierarchy model in object-oriented database. The relationship between the object and the class is established through the relevance of the attribute to the fuzzy class and the semantic distance between the object and the class. The relationship between the class and the sub-class is established through the relevance of the attribute to the fuzzy Glass and the semantic distance between the class and the sub-class. Simultaneously, the problem of multiple inheritance in class hierarchy is considered. This model extends existing object-oriented data models and is compatible with it.
