文章通过社会网络分析方法利用点中心度等指标把某些主题的关键词在网络中的地位及其相互关系以量化的形式予以揭示,定量地描述某一研究主题在虚拟关键词网络中的地位,并把某些主题的关键词网络以可视化的方式呈现出来,有助于概貌性了解研究领域的研究热点,横向和纵向分析领域学科的发展,对科技查新工作面对浩瀚的信息资源组织的热点发现,针对具体的查新主题,拓展信息检索领域,实现高效的、前瞻性的查新知识服务作了有益的尝试。
The article uses the social network analysis method to make use of such indicators as the degree of point center to reveal the key words in the network and their mutual relations in the form of quantification to quantitatively describe the status of a certain research topic in the network of virtual key words , And visualize the key words of some thematic networks. It helps to understand the research hotspots in the research field, the development of the disciplines in the field of horizontal and vertical analysis, the investigation of science and technology in the face of the vast information resources organization The hot spot has made helpful attempts to find new topics, expand the field of information retrieval, and realize efficient and forward-looking new knowledge services.
