摘要
[目的 /意义]针对h指数无法区分作者贡献以及忽略时间因素影响的缺点,提出一种新的评价指标以细致评价作者学术成就。[方法 /过程]首先,借鉴在h指数中考虑作者合作的思想,计算出hc指数以区分作者贡献。随后,将高贡献度、高被引文献的距今年数这一时间因素融入h_c指数,构建出h_c(t)指数。最后,利用图情领域的作者文献数据,从h_c(t)指数的稳定性、区分性和相关性进行实证分析。[结果 /结论]实证表明,h_c(t)指数名次变化明显且稳定性较强,对相同h指数的学者区分能力较好,区分度达到75.86%。此外,h_c(t)指数能够反映作者的近年学术活跃度与研究方向。
[ Purpose/Signification ] Aiming at solving the problems of failing to distinguish the contributions of art author and ixegligence of the influence of time of the h-index, this article presents new evaluation index for author's contribution assessment. [ Method/Process] Firstly, referring to the thinking reflected in the h index - taking author's cooperation into consideration, hc index is calculated to differentiate the contribution of authors. Secondly, based on hc -index, the article constructs an he(t) index by integrating the number of years to date of high contribution and highly cited papers into the he index. Then the article analyzes the stability, differentiation and correlation of he(t) index based on the literature data of 35 researchers from CNKI database (2005-2014 ) in the subject of "Library and Information Science and Digital Library". [ Result/Conclusion] The results show that he(t) index is superior in its diseriminative capability, it can dif- ferentiate the scholars with the same h index, the hc(t) index ranking change is obvious and has certain stability, and the differentiation rate reaches 75.86%. In addition, hc(t) -index could reflect an author's reeent research performance and directions.
