近10年国内索引方法与技术研究的文献计量分析

The Bibliometric Analysis on Domestic Research of Indexing Method and Technology in Recent Ten Years

采用文献计量学的方法,从文献数量的年度分布、被引量和下载量、作者及机构分布几方面对国内索引方法与技术研究的文献进行了统计分析,利用Cites Pace软件绘制了研究热点聚类图。结果表明:专门研究索引方法与技术的研究者比较少,稳定的核心研究群体尚未形成;核心研究人员比较集中于硕士、博士群体;总体上,该领域研究面还比较窄,主要集中于空间索引、全文检索、XML索引、时空数据库、位置敏感哈希、时态索引等6个热点研究领域,关于应用与服务相关的研究还比较欠缺。

By means of bibliometric method, this paper conducts a statistical analysis on domestic research literature of indexing method and indexing technology from the aspects of the annual distribution of the number of literature, the amount of citations and downloads, the distribution of authors and institutions, and draws a research hotspots clustering map by using the software Citespace . The results show that only a few researchers specially study the indexing method, and stable core research groups have not yet been formed; the core researchers are relatively concentrated on the master＇s group and doctoral group; generally speaking, the research scope of this field is relatively narrow, mainly focusing on six hot research fields of the spatial index, full text retrieval, XML index, spatial and temporal databases, location sensitive hash and temporal index, besides, the related researches on the application and service are still relatively lacking.
