国外语义web门户的实践研究

Study on Theory and Application of the Semantic Web Portals

柏纳李(Tim Berners-Lee)在2001年提出"语义网",指出语义网是当前WWW的扩展,网络中所有的信息都具有语义,可以实现机器可识别语义的数据的自动存取和利用,便于人和计算机之间的交互与合作。朝着这个方向,语义web门户的功能实现和建设技术成为了科研工作者研究语义网的平台和实现缩影。语义web门户基于本体技术,采用一系列的语义web技术实现了语义查询、语义浏览、语义发布和语义个性化。本文对语义web门户的含义进行了限定,在此基础上重点调研了相对完善的语义web门户的实践研究,对其发展脉络和发展特征进行了分析。

Tim Berners-Lee put forward ＂semantic web＂ at year 2001, and he pointed out that semantic web was the evolution of WWW .Semantic web in which all the information is semantic can enable data that can be understood by the machine automatically accessed and used. As a result, the Semantic web can make the exchange between people and computer mcre convenient and efficient. Because of the close relationship between semantic web and semantic web portals, we can take semantic web portals as the reduction of Semantic web. Meanwhile, the functionality implement and technology strategies of semantic web portals have become the important focus for the research of Semantic web. Semantic web portals based ontology make use of a series of semantic web technologies to enable semantic query, browse and publication as well as semantic personality. The paper firstly studies the research on semantic web portals in foreign countries and analyse the evolution skeleton and actuality of semantic web portals.
