摘    要:在信息服务向知识服务过渡中,知识元被认为是实现知识服务的实体单元。归纳已有知识元的研究方法,从情报学的视角探讨知识元的概念,提出知识元由导航信息和语义内容两部分组成、二者构成知识元的独立实体、单一的关键词不是知识元的观点。接着,从信息与知识变换的角度讨论文本知识元谱分析与提取的算法和实现。实验结果表明该方法具有可操作性和实践性。

关 键 词:知识元  语义链接  模型研究

Abstract:The knowledge element is considered to be the entity unit of knowledge services from the transition of information services to knowledge services. This paper, firstly, summarizes the existing the research methods of knowledge element, discusses the concept of the knowledge element from the perspective of information science, considers that the knowledge element consists of two parts, namely, navigation information and the semantic content, which is an independent entity of a knowledge element constitutes. However a single keyword is also not a knowledge element. Follow the discuss of transformation approach of information and knowledge from the knowledge spectrum of text, analysis extraction algorithms and implementation. Experimental results show that our approach is feasible and practical.
Keywords:knowledge element  semantic links  model research
