| 摘 要： | 给出一种基于主题词频和g指数的研究热点分析新方法，该方法具有同时计量主题词频和该主题论文的质量以及自然选取主题词数量等特点。以信息计量学为例，实证分析了主题词g指数与词频及该主题论文质量的关系。理论推导证明：主题词g指数近似等于主题词g核心内论文的平均被引。

| Abstract: | A new method for research focus analysis based on the frequency of topic words and g-index is given. The frequency of topic words and the quality of paper represented by topic words were considered simultaneously. Moreover, by the method, the number of topic words can be determined in a natural manner. Taking Informetrics as example, we empirically analyze the relationship between g-index of topic words and the frequency of topic words, quality of paper represented by topic words. Theoretic deduction indicates that g-index of topic words is approximately equal to the average number of citations per paper in g-core of topic words. |
