| 摘 要： | 考虑到微博与传统文献的相似性，本文旨在探索h指数、g指数和p指数在微博影响力评价中的应用，通过对比三者的评价结果来探索3种指数在微博影响力评价上的合理性和各自的特点。首先，基于信息计量领域中的h指数、g指数和p指数的定义，针对微博转发数、评论数和点赞数构建9项微博影响力评价指标；然后，以40所"双一流"高校的微博为实证对象，通过整体对比、相关性分析等方法，将h指数、g指数和p指数对微博影响力的评价结果进行了对比。结果表明3个指数在微博影响力评价中都有一定合理性；在区分度方面，g指数和p指数都优于h指数，其中，p指数最具优势，并能挖掘高影响力的非活跃用户；在敏感度方面，h指数不易受极端值影响，更适合评价微博影响力。

| Abstract: | Considering the similarities between microblog and traditional literature,this paper aimed to explore the application of h-index,g-index and p-index in the evaluation of microblogs' impact and compared the evaluation results of the three to explore the rationality and characteristics of the three indexes on the evaluation of microblogs' impact.First of all,based on the definitions of h-index,g-index and p-index in the field of information measurement,this study put forward nine indexes for the evaluation of microblogs' impact for forwarding,commenting and liking.Then,it took the campus microblog as the research object,through the overall comparison,correlation analysis and other methods,to compare the evaluation results of microblogs' impact based on h-index,g-index and p-index.The results showed that the three indices had their rationality in the evaluation of microblogs' impact.In terms of discrimination,both the g-index and the p-index were better than the h-index.Among them,the p-index had the most advantages and could find high-impact inactive users.In terms of sensitivity,the h-index was less susceptible to extreme values,which was more suitable for the evaluation of microblogs' impact. |
