【摘要】 随着制造业信息化的发展,机械领域本体相关技术的研究越来越受到研究者们的重视。本文依托国家自然科学基金项目“支持协同产品开发的多学科本体集成方法与评价机制”(50875158)、山东科技大学研究生科技创新基金项目“面向多学科的机械领域本体集成技术研究”(YCA100324),研究机械领域机械零部件本体构建与集成相关的关键技术,分析本体技术在机械领域中发挥知识组织功能的实用性意义,建立了一种协同共建机械领域本体的方法,并依靠实例给出了整个构建过程。最后对协同本体的集成技术等相关内容进行了分析和研究。本文首先分析本体技术用于机械领域进行知识组织的可行性及优越性,认为本体方法是知识组织的一种极具代表性的方法,通过分析比较本体与叙词表在逻辑表达形式、结构特性、形式化程度三个方面的区别与联系以及本体与分类表在关系表达方式和结构组织两方面的区别与联系,指出了本体在知识组织方面具有明显优势且具有基础性地位,以及知识组织向机器可处理的智能化方向发展的趋势。此外,对本体与语义网的关系进行了分析与探讨。与传统构建本体的专家分类法不同,本文给出一种网络协同环境下机械零部件本体的构建方法,采用以网络为平台的大众分类法,分析了机械零部件在网络协同环境下根据大众分类法对零部件进行标签编码,并通过零部件标签与本体技术相结合的方法,利用本体构建工具protege建立了一个在网络协同环境下能够较真实和全面揭示零部件信息特征的本体模型,为机械产品信息的交流、共享和知识重用提供了有效支持。本体协同的实现属于本体集成的一种类型,本文分析了本体集成的相关技术,采用本体融合的方法对协同共建的子本体进行了集成研究,通过实例实现了本体的集成。更多还原

【Abstract】 At present, the research on mechanical ontology is more and more important along with the development of mechanical informationization, and many researchers are studying the technology about mechanical ontology. This dissertation is supported on the project of National Natural Foundation of China—Muti-subject ontology integration and evaluation supporting collaborative product development (50875158), Innovation Program of Shandong University of science and technology—Research on mechanical ontology integration oriented multi-subject (YCA100324). In this dissertation, the key technology about mechanical components ontology building and integration is studied. Then the function of ontology in knowledge organization is analyzed, and the process of building the mechanical components ontology is supposed depending on an example. Finally, ontology integration of collaborative ontology is analyzed.First of all, feasibility and advantage of ontology application in knowledge organization are analyzed. Ontology is a representative method of knowledge organization. This paper compared and analyzed the differences and relations about logic expression, structure characteristics and formalization between ontology and thesaurus. It also compared and analyzed the differences and relations about relationship expression and structure organization between ontology and taxonomy. Based on all of the comparative researches, the conclusion presents the obvious advantage and fundamental role of ontology in knowledge organization, and the trend of intellectualization to process knowledge by machines. Further more, the relationship between ontology and Semantic Web is analyzed and discussed.Different with the traditional expert classification of building ontology, method of ontology building in the networked and collaborative environment is gived. Web-platform folksonomy is used to analyze the label encoding of mechanical components in the networked and collaborative environment. And according to the combination of labels of mechanical components and ontology technology, the ontology model is given based an instance by protege to reveal the information characteristics of mechanical components more realistically and more completely. With the trend of realization of manufacturing informationization, Building the mechanical components ontology would be useful for communication, sharing and knowledge reusing of mechanical products.The process of getting the result of collaborative ontology is one method of ontology integration. The dissertation analyzed the related technology about ontology integration. Ontology merging is used to support the the ontology integration. One example is given to integrate collaborative ontologies.更多还原
