| 摘 要： | 数据模型研究是设计按内容检索的图象数据库系统的基础．本文根据图象信息系统的特点，将面向对象模型与超语义模型有机结合，提出了一种新的图象数据模型及相应的说明语言．该模型以紧耦合方式融合了语义数据模型和知识模型的特点，并增加了表示图象对象间空间关系的机制，使得该模型可以更好地描述图象信息系统中的图象数据、领域知识以及空间关系语义．

| Abstract: | Data model studies offer a basis for the design of a image database system with content based retrieval. Based on hyper semantic data models, a new data model for image information in image database systems with content based retrieval is presented and the specification language for the model is proposed in the paper. The model incorporates properties of semantic data models with some concepts of AI and has the mechanism for capturing spatial semantics to increase modeling capability for spatial relationships. |
