Progress in the Development of National Knowledge Infrastructure

This paper presents the recent process in a long-term research project,called National Knowledge Infrastructure(or NKI).Initiated in the early 2000,the project aims to develop a multi-domain shareable knowledge base for knowledge-intensive applications.To develop NKI,we have used domain-specific ontologies as a solid basis,and have built more than 600 ontologies.Using these ontologies and our knowledge acquisition methods,we have extracted about 1.1 millions of domain assertions.For users to access our NKI knowledge,we have developed a uniform multi-modal human-knowledge interface.We have also implemented a knowledge application programming interface for various applications to share the NKI knowledge.     

MUIS: 一种新型的多领域信息共享联盟系统及其应用

信息资源共享已经成为时下各行各业的一个研究热点.针对不同行业的信息共享需求以及共享过程中的访问效率问题,提出了一种多领域信息共享联盟模型MUIS,对模型的结构、功能框架以及相关核心技术,包括异构数据库的标准化处理、URI远程访问技术、跨领域检索、快速查询、分支检索以及自然语言查询等进行了详细讨论. MUIS已经实现,并且在包括农业信息检索、黄页信息查询等多个领域中进行实验和应用.
