摘要
本文提出了基于关系／网状的语义超图描述模型及各种操作。引入面向对象的方法，统一描述对象和元组。提出了对象间的语义联系、基于联系的各种操作和施加于对象的方法机制。在语义超图层次，描述和操作了不同语义类的对象；在语义子图层次，描述了每一语义类的对象间的多对多关系及其操作。因此。
Using object oriented method to unify descriptions of both objects and tuples, the semantic hypergraph model based on relation and network presents the semantic links among objects, some operations on links and the method mechanism imposed on objects. In the level of the semantic hypergraph, the model can describe and operate the objects belonging to different semantic classes. While in the level of semantic graph, the model can describe and operate many to many relations of the objects for each class.
