[目的/意義]解決h指數及類h指數缺乏對科研工作者整體學術進行綜合評價的問題。[方法/過程]著重考慮科研工作者前h指數篇學術論文的綜合貢獻,構建hw與hw_t兩個加權h指數模型,選取圖書情報領域近年來較為活躍的30位學者進行實證分析。[結果/結論] hw指數是一個彰顯高被引論文、考慮科研工作者每篇文獻貢獻度的綜合評價指標;與h指數相比,hw指數易于區分學者科研貢獻度,并在一定程度上減少自引對結果的影響。hw_t指數側重學者近年研究成果,結合過往貢獻,在短期評價中對青年學者和過往貢獻較大的學者均更為合理;對比分析hw指數與hw_t指數,可以發現潛力學者。

[Purpose/significance]This paper aims to solve the problem that h-index and h-type index cannot make comprehensive evaluation of scientists’ overall academic contribution.[Method/process]Considering the contribution of scientists’ first h pieces of academic papers,the paper proposes the weighted h-index model of hw-index and hw_ t-index,and uses the data of 30 active Chinese scholars in Library and Information Science field for empirical analysis.[Result/conclusion]Revealing highly cited papers and considering the contribution of scientists’ every paper,hw-index not only weakens the influence of self-citation on the results,but also makes it easy to distinguish scientists’ contributions when compared with h-index.The hw_ t-index focuses on scientists’ papers in recent years and previous contributions,so it is more reasonable to evaluate young scientists in a short period and scholars who have more contribution in the past years.Potential scholars can be identified by the way of comparing hw-index and hw_ t-index.
