超媒体系统中的语义约束问题研究

The Research on the Semantic Constraints in Hypermedia Systems

提出了一种基于数据库模式的超媒体语义网络模型 ,该模型通过引入模式约束图 ,对超媒体系统中的关系约束进行了分类 ,并给出了相应的约束检测算法 ;通过引入视图机制提出了结构约束的概念 ;通过扩充模式约束图的属性 ,描述了超媒体特定应用领域的计算约束 ,从而从整体上对与应用领域无关至特定应用领域的语义约束进行了深入的研究 .

A database schema based semantic hypermedia model is proposed. By introducing the concept of schema constraint graph, the relational constraints are classified and the corresponding detection algorithms are given. By expanding the database schema on the attribute side, the computational constraints are described depending on the specific application area. In general, we made a deep and effective research on the hypermedia semantic constraints from application area independent to specific application area dependent.
