基于语义Web的IETM领域知识表示与推理

Study on IETM Domain Knowledge Representation and Reasoning Based on Semantic Web

为了使IETM（交互式电子技术手册）内容便于机器理解与推理，需要建立本体，同时IETM内容应以本体所定义的元数据进行标注。本文定义了领域知识与IETM领域知识之间的关系，概述了语义Web的本体语言，权衡了其在知识表示与推理两方面的利弊，选择OWLLite作为IETM本体描述语言，然后完成了IETM领域知识的表示与推理。本文研究成果将IETM本体开发归纳为知识表示、推理及集成，使得IETM本体开发过程更清晰，更具有操作性。

To make IETM （interactive electronic technical manual） contents understandable to machine and suitable for inference, ontology needs to be established, and the IETM contents should be annotated with metadata which are defined as terms in ontology. The relation between domain knowledge and IETM domain knowledge is explained; the overview of ontology languages for the semantic Web is introduced; based on trade-off between expressivity of knowledge and complexity of reasoning problems, OWL Lite is selected as ontology language; then IETM ontology representation and reasoning for the semantic Web are proposed. From these discussions, the basic situations of domain ontology representation, reasoning and integration for the semantic Web are clarified, so the basic knowledge of developing IETM ontology for the semantic Web is provided.
