基于Internet的分布式设计知识资源检索策略

A Knowledge Search Strategy over the Internet-based Distributed Network

提出了一种快速、高效的两级知识检索方法：首先根据 “加权关键词匹配定位法”来有效、准确地定位知识站点；然后“约束驱动知识检索”方法在所定位的知识站点中准确获取满足用户意愿的具体知识。两级知识检索方法可以改善原有传统检索方法的有效性，使设计开发人员在分布式知识资源环境下的知识检索效率大大提高。

In the paper, knowledge search approaches in the Internet-based distributive network environment are discussed. An efficient and effective two-step strategy of knowledge search is then proposed to support designers locating and retrieving design knowledge quickly and exactly from distributive knowledge resources network. For orientating the position of knowledge sites, an approach, weighted
