知识界面在NKI中的应用

Application of Knowledge Interface in NKI

国家知识基础设施(NKI)构建存放大量的多学科的专业知识的知识服务器,提供知识服务。为了在用户和知识服务器之间建立有效的知识查询通道,需要设计一种知识界面。该文介绍设计和实现一种新颖的基于自然语言的知识界面。这一知识界面的特点是:(1)知识查询不依赖于特定用户、不依赖于特定查询方式和不依赖于特定查询内容;(2)用户与知识服务器的对话可以是上下文相关的,这为用户连续查询知识提供方便。

National Knowledge Infrastructure(NKI )consists of multi-disciplinary multimedia knowledge servers,each containing a great amount of domain-specific knowledge.An intelligent knowledge interface is needed to allow the end-user an effective access to the knowledge servers,and this paper presents such a knowledge interface.The proposed knowledge interface is independent of user background,style of query,and content of query.It also allows the end-user to pose knowledge queries in a context-dependent fashion.
