摘要： WWW是信息时代的重要标志。基于WWW的信息管理系统不仅要能运行在不同的平台上、分布的信息网络中，而且还能提供通用的平台与大量的、独立的、多类型的数据源和应用程序进行交互。开放知识服务体系OKSA就是为实现这一目标而提出的，在开放的Web资源环境中，建立动态的、跨平台的虚拟知识环境，使得人们能够获取、发布、共享和管理各种Web资源，并向用户提供按需的知识服务以支持协同工作、问题求解和决策支持等。

Abstract: The WWW is landmark of information era. Information systems based on WWW should not only run on different platforms and distributed information networks, but also provide a common platform to interoperate with large independent and various data sources. Open knowledge services architecture (OKSA) is proposed. It is used to construct a dynamic, and cross-platform virtual knowledge environment, which can help people to acquire, publish, share, and manage Web resources, and provide on-demand knowledge services to support cooperative working, problem solving and decision support.

Key words: Knowledge services, Semantic Web, Ontologies
