摘要
制造的网络化使得企业能够快速查找、获取和使用全球的制造资源,避免重新发明,从而节约成本并提高对市场的快速反应能力。基于关键字的传统查询方法有许多不足,本文设计实现了一个基于知识的信息服务平台,通过构造领域模型实现基于语义的信息查询,能够有效地满足企业对制造资源信息的要求。
The Internet makes it possible for the manufacturing enterprises to find, access, evaluate and make use of manufacturing-oriented resources around the world, avoiding 'reinvent the wheel' and thus reducing the cost and improving the responsiveness to market opportunity. 'based search' has some weaknesses .This paper designs and realizes a knowledge-based framework for information services. Semantics-based information query can be implemented,and the system is able to meet the requirements of information searching of enterprises with more efficiency and precision
