摘要
科学有效地从浩瀚的科技文献中探测出领域的新兴趋势,是情报研究领域关注的热点和难点问题。提出了基于文献计量的新兴趋势分析方法,首先对领域数据进行共被引聚类分析,找出突现文献的施引文献作为后续分析的数据源,然后通过"关注度"和"实用性"来分析新兴趋势:"关注度"分析通过高频关键词共现及聚类发现新兴趋势,"实用性"分析新兴趋势论文作者国家、机构以及期刊的平均影响因子是否呈增大的趋势来验证是否满足条件。最后用生物材料作为实例进行了实证研究,验证了其有效性。
Detecting emerging trend topics from lots of papers is one of the difficulties for information research. This paper put forward e- merging trend analysis based on bibliomeuic method. Firstly, this paper used co-citation method to find out burst cited references and then downloaded their citing papers as data source for the following analysis. This paper used two indexes（ attention and practicality） to detect emerging trend topics. The ＂attention＂ index through the high frequent keywords was used to create co-occurrence matrix and visualiza- tion, summing up the emerging trend topics; the ＂practicality＂ index through the countries, organizations and average impact factor, was used to evaluate whether the selected emerging trend topics meet the demands. This paper used biological materials as one example to ana- lyze the emerging trend.
