发布时间:2019-04-21 10:12
【摘要】:全国第五次情报检索语言发展方向研讨会带来了情报检索语言发展问题的又一次大讨论。本文以1979-2008年该领域发表的期刊论文为数据源,获得高频关键词,构造其相异矩阵,利用SPSS软件进行聚类分析,并绘制出战略坐标图。结果表明:情报检索语言的学科内部结构正在发生变化,研究对象逐渐增加,在网络环境下的应用不断拓展,搜索引擎、网页信息自动处理等概念不断出现。该探索性研究较好地演绎了近三十年我国情报检索语言的发展。
[Abstract]:The fifth national seminar on the development direction of information retrieval language has brought about another big discussion about the development of information retrieval language. In this paper, the periodical papers published in this field from 1979 to 2008 are used as the data source, the high frequency keywords are obtained, the dissimilar matrix is constructed, the cluster analysis is carried out by using SPSS software, and the strategic coordinate diagram is drawn. The results show that the internal structure of the information retrieval language is changing, the research objects are increasing gradually, the applications in the network environment are expanding constantly, the concepts of search engine, web information automatic processing and so on appear constantly. This exploratory study well deduces the development of information retrieval language in China in the last 30 years.
