中文摘要：

文章讨论了Internet的增长和普及带来的科学研究对象和方法的巨大变化，科学家在跨领域合作研究过程中对数据的语义和复杂度要求越来越高，寻找关联方式发现知识成为科学家所面临的最严峻的挑战。面对这一挑战，文章提出构建知识元语义网格平台，实现以知识元为知识单位的知识发现服务体系结构。文章对基于网格的知识发现概念、网格的知识服务结构、基于知识元的语义网格知识发现基本模型作了研究。

英文摘要：

This paper discusses a new problem carrying by great changer of the object and method for science research.Many scientists focus on the sharing of computing resources,however,much of scientific process with relatively needs significant semantic and data complexity.Therefore,scientists is faced with austerity the challenge come from looking for knowledge of relating discovery.Affront this challenge, the new problem of knowledge element Semantic Grid of the platform of knowledge service and knowledge discovery is the design.Which is a new development direction for providing grid-based knowledge discovery services.
