| 摘 要： | 通过选取我国情报学博硕士学位论文的高频关键词进行两两统计其在同一篇文献中出现的次数,来构造共词矩阵,进而转化为相关矩阵、相异矩阵。对不同的矩阵进行多维尺度分析、聚类分析、因子分析。综合分析结果发现当前的研究热点主要有三方面:信息检索技术的理论与实践,图书馆的建设与服务,电子商务、电子政务的信息化。

| Abstract: | High frequency in Information Science dissertations of Ph.D.and master degree in China are chosen to form the co-word matrix.Then transform the co-word matrix into correlation matrix and dissimilarity matrix.Three different methods analyze the appropriate matrix to find out there are three main streams which reflect current research hotspots.They are information retrieval theory and practice,library construction and service,information-based e-commerce and e-government. |
