摘要/Abstract

摘要：

为解决产品服务活动中知识难以被发现和重用的问题,对产品服务过程所涉及的知识进行了分析,提出了基于本体的知识表示方法,
该方法可实现本体的定义与建模,以及本体内各概念相似度的评定。通过对领域本体的构建,
实现了服务过程所涉及知识的逻辑结构与具体内容的全面语义描述和后台并联。构建了基于本体的产品服务知识管理系统,该系统能实现产品服务活动案例所涉及知识的获取和重用，满足知识源于服务
活动,又重用于服务活动的循环。最后以某航空发动机非计划维修服务为例，验证了该知识表示方法的有效性。

关键词: 知识表示, 服务本体, 产品服务过程, 知识管理

Abstract:

To solve the problem that knowledge could not be discovered and
reused easily during product service activities,the needs of knowledge representation in
the process of product service were discussed,and an ontology-based knowledge representation method for product service process was proposed.To better manage the ontology,
a solution for ontology management was developed for ontology definition,building,and evaluation of semantic similarities of concepts among ontology domains.The logical structure
and details of the knowledge involved in the product service process were described by ontology building.An ontology-based knowledge representation framework was developed for the reuse of knowledge unambiguously,which realized the knowledge originated from
the service process and served service process.An initial attempt was made to prove the feasibility of the knowledge representation by example of aircraft engine unscheduled maintenance.

Key words: knowledge representation, service ontology, product service process, knowledge management
