基于CommonKADS模型的知识库应用

A Knowledge Repository Application Based on the CommonKADS Model

针对中小规模知识库系统中存在的知识表示能力不够、知识搜索广度不足的问题,本文结合CommonKADS模型从两个方面着手来解决:一方面用本体对知识进行表示,增强知识语义表达能力;另一方面,为了实现不同领域知识间的交流,将桥本体引入到知识模型中,发挥其在领域之间的“桥梁”作用,从而保证和提高系统的问题求解效率和能力。最后,以操作系统知识为背景,介绍知识库的实现并对措施的有效性给予验证。

Considering the problems such as the deficiencies in knowledge representation ability and knowledge search range in small- and medium-sized knowledge repository systems, the paper resolves them by two ways with the CommonKADS knowledge model. On the one hand, we use ontology to represent knowledge in order to improve the ability of representation; on the other hand, we introduce bridge ontology to knowledge models to realize communications among the different domains which act as the role of a bridge function. Thus, the system efficiency and ability are ensured and enhanced. At last, the paper takes computer operating system as an example to introduce the repository＇s realization and verify the effectiveness of the solution.
