摘要： 以产品数据管理为例,探讨了虚拟企业中面向信息共享的知识管理机制。所考虑的知识不同于传统的知识管理系统,它包括元数据、企业本体和数据转换(术语与格式转换)。元数据提供了企业数据向导的功能,企业本体则对企业数据的语义进行说明,增强了系统的搜索能力;而数据转换则实现不同系统间的术语与格式的转换,有利于虚拟企业环境下实现分布式、异构数据库信息共享。

Abstract: This paper, taking product data management as an example, discusses knowledge management for information sharing in virtual enterprises. The knowledge discussed here includes metadata, ontology and mapping relationship, which differs from that in the traditional if-then based system. Metadata provides users with a map of product data that help them to locate proper information. Ontology enables a semantic-based search that can improve search effectiveness. Mapping relationship supports the automatic transformation of data format and translation of terminologies used in different applications.
