【摘要】 进入21世纪,伴随着因特网的迅速发展,网络信息以几何级数飞速增长,新的学科、概念、主题层出不穷,而且信息日趋复杂,质量参差不齐。关键词检索依然是主流方式,这种方式返回信息量大,但符合要求的少。为了更准确、更有效地查找到自己所需要的网络资源,建立专门针对某一学科领域的检索工具,即动态规范词表,已经成为网络资源检索的迫切需要。本文在对当前使用传统词表面临的问题研究分析基础上,提出了一种网络动态规范词表的构建方法。网络动态规范词表是在普通传统词表的基础上,添加计算机元素,在计算机辅助之下构成的人机结合的新系统。本文首先对《中国分类主题词表》纸质版及电子版进行分析,并分析比较国外著名网络化词表的优劣;其次,研究动态规范词表的基本理论,包括语词来源、选词依据、词表控制程度及词表功能;随后,通过人工管理及计算机自动管理,分别从管理层面及技术层面对词表的构建方式加以阐述,可以帮助用户选择合适的检索词,构造出准确的检索式;并在此基础上,构建动态规范词表系统模型;最后,对动态规范词表的应用做以简单介绍,动态规范词表可以在网络搜索引擎中智能化地为用户提供更优的检索策略,供检索使用,减少误检和检索效率低的问题,以此来提高搜索引擎的检索质量,提升用户满意度。更多还原

【Abstract】 Entering the 21st century, with the rapid development of the Internet, the network information increase quickly and complicatedly, new disciplines, concepts and themes emerge endlessly and variously, but the quality is unknown. Keywords retrieval way is still the mainstream manner, but this kind of method returns less required information. In order to find network resources more accurately and effectively, establishing retrieval tools on a particular subject areas --dynamic standard vocabulary, has becoming urgent to network resources retrieval.Based on analyzed the problems caused by using traditional vocabulary in the current society, this paper put forward a kind of method to construct the network dynamic standard vocabulary. Network dynamic standard vocabulary is a new system which based on traditional vocabulary, and infused computer technology. Firstly, there is analysis of paper-based edition and electronic edition vocabulary, meanwhile, comparing the advantages and disadvantages of foreign vocabularies; secondly, there is basic theory research, including words source, words selecting basis, vocabulary control degree and vocabulary function; then, discussing the construction ways of vocabulary by means of artificially management and automatic computer management, which can help users to select proper search words, construct accurate retrieval model; and on this basis, building vocabulary system model; finally, there is simple introduction of vocabulary application, which can provide more intelligent retrieval strategy in the network search engines to reduce search problems, also it can improve the quality of search engines and the users satisfaction.更多还原
