基于Ontology和XML的非结构化信息语义表示机制研究

针对日益增长的非结构化信息实际应用的需要，结合Ontology（本体）和XML各自的优势，提出一种用于分布式环境的非结构化信息语义表示机制，该机制从某一领域的概念化模型——Ontology——出发，通过设计Ontology到XML Schema的映射算法将Ontology提供的共享概念模型、继承以及推理机制等语义元素融入到XML简便灵活的语法规则之中，从而形成一种新的能表达信息语义的模式语言，它不仅能有效提高信息的语义互操作性，也为进一步实现语义信息处理打下了一定基础。

SEMANTIC REPRESENTATION OF UNSTRUCTURED INFORMATION BASED ON ONTOLOGY AND XML

Aiming at increasing application of unstructured information, combining with the respective advantages of Ontology and XML, this paper puts forward a semantic-oriented unstructured information representation mechanism used in distributed environment. The mechanism begins with Ontology of some domain by designing a mapping algorithm originating from Ontology to XML Schema, and it integrates the semantic elements like shared conceptualization, inheritance and inference, etc. of Ontology into the simple, flexible syntax rules of XML, thereby forms a new schema language for expressing semantic content, which enhances the semantic interoperability of information efficiently and lays the foundation for farther semantic information processing as well.
