摘要
Web 服务作为 Web 技术的最新发展成果,它的目标是将不同个人、组织甚至公
司提供的服务无缝地进行连接和通讯,在 Web 上建立一种松耦合的 Web 应用。但是
要想使分布于 上的服务器可以通过 Web 更自动化地,更智能化地交互,就
必须解决目前 Web 上广泛存在的信息格式的异构性、信息语义的多重性以及信息关
系的匮乏和不统一等问题。将语义的概念和相应技术引入 Web 服务技术中,将从根
本上解决以上问题。
本文以大型单件小批制造业的物资管理领域为应用背景,在对语义网、本体论及
Web 服务相关技术研究的基础上,提出了将本体论应用于制造业 Web 服务描述的思
想,具体实现服务描述的步骤如下:首先,对物资管理领域的业务流程进行了详细
分析,抽取出概念术语;其次,利用语义网本体语言(OWL)和约束公理构建领域
本体;然后,在领域本体的基础上将物资管理领域中的管理活动抽象为原子过程,
并运用语义网服务标识语言(OWL-S)的上层服务本体实现 Web 服务描述;最后,
通过本体建模工具 Protégé 完成上述步骤的可视化定义。此方法利用本体中丰
富的关系表达传统关键词匹配所不能表达的语义,为实现自上而下的制造业信息系
统集成和重用提供了可借鉴的资料。

Abstract
As the latest achievement in the research of web technology, web services are aimed at
building a loose coupled web application through seamless connection munication
of services offered by different individuals anizations. However, it is essential to
solve the problems such as the information heterogeneity on the web, semantic multiplicity
of information and the lack and disunion of the information relation, so that the servers
distributed on the can interact more automatically and intelligently. Introducing
semantical concept and related technology into web services will solve these problems
radically.
This paper takes the domain of material management in manufacturing enterprises of
large-scale, single-piece and small batches as application background. Based on semantic
web, ontology, and related technology of web services, this paper proposes an idea that is
to apply ontology to the web services description of manufacturing. The specific steps of
realizing services description are as follows. First, analyze the business process in the
domain of material management in detail to extract concept terms. Second, build domain
noumenon by using OWL and constraint axioms, and then based on the domain ontology,
abstract the management activities in the domain of material management to atomic
process, and at the same time, use the upper ser
