【摘要】 语义网是提高网络信息检索质量的重要途径。利用现在流行的Web信息检索系统,扩展其处理语义Web文档中的语义评注的能力,采用更有效的文档分类算法,将语义Web文档组织成蔟,提高检索质量。介绍的算法与标准的基于图匹配算法相比,计算代价降低,便于后续的存储、抽取和处理等工作。更多还原

【Abstract】 The semantic web offers a promising solution to improve the quality of information retrieval on the world wide web.Prevalent web information retrieval systems are extended to handle annotations in semantic web languages.Moreover,an effective document ca-tegorization algorithm is used to semi-structured semantic web documents(SWDs) which significantly differs from standard methods based on graph-matching algorithms.SWDs is grouped into clusters so that different storage,retrieval,and processing techniques are effectively exploited.更多还原
