【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。
[Abstract]:With the development of manufacturing informatization, Researchers pay more and more attention to the research of ontology-related technology in mechanical field. This paper relies on the project of National Natural Science Foundation of China "Multidisciplinary Ontology Integration method and Evaluation Mechanism to support Collaborative Product Development" (50875158), Shandong University of Science and Technology (Shandong University of Science and Technology). The Graduate Science and Technology Innovation Foundation Project "Multi-disciplinary Ontology Integration Technology Research in Mechanical Domain" (YCA100324A), the key technologies related to the construction and integration of mechanical parts ontology in mechanical field are studied. This paper analyzes the practical significance of ontology technology in developing the function of knowledge organization in the field of machinery, and establishes a method of building the ontology of mechanical field in cooperation. Finally, the integration technology of collaborative ontology and other related contents are analyzed and studied. This paper first analyzes the feasibility and superiority of ontology technology in the field of mechanical knowledge organization, and considers that ontology method is a very representative method of knowledge organization, and through analyzing and comparing ontology and thesaurus in the form of logical expression. The differences and relations between ontology and classification table in relation expression and structure organization are discussed. It is pointed out that ontology has obvious advantages and basic position in knowledge organization. In addition, the relationship between ontology and semantic web is analyzed and discussed. Different from the traditional expert classification of building ontology, this paper presents a construction method of mechanical parts ontology under the network collaborative environment, and adopts the popular classification method based on the network. This paper analyzes the label coding of mechanical parts according to the common classification method under the collaborative environment of network, and the method of combining part label with ontology technology. An ontology model which can reveal the information characteristics of parts and components in a network collaborative environment is established by using the ontology construction tool protege. It provides an effective support for the exchange, sharing and knowledge reuse of mechanical product information. The realization of ontology collaboration belongs to a type of ontology integration. This paper analyzes the related technologies of ontology integration, and uses the method of ontology fusion to study the integration of the sub-ontology of collaborative cooperation. Finally, the integration of ontology is realized through an example.
