摘要
针对目前期刊网络传播力评价研究相对薄弱的状况,探究运用z指数评价期刊网络传播力的应用效果。采集图书馆、情报学与文献学期刊的样本数据,考察基于下载量的z指数(z d指数)在期刊网络传播力评价中的有效性、科学性和先进性。研究结果显示z d指数与传统期刊评价指标之间存在相关性,表明z d指数对期刊的评价具有一定的有效性;z d指数与h d指数相比,在区分度、灵敏度及整体性方面具有优势,较p d指数的考察维度多,弥补了p d指数不能考察数据分布的不足,同时作为网络计量指标的z d指数具有时效性强、读者参与度高、抗干扰能力强、对期刊价值的反映程度高等特征,凸显出评价指标的科学性;与总下载量、篇均下载量、h d指数、p d指数等网络指标相比,z d指数在把握整体、又突出重点的同时,进一步深入到考察期刊下载量数据的分布状况中,矫正了数据分布对评价结果造成的偏差,说明评价指标具有明显的先进性。
In view of the relatively weak current research on the evaluation of journal network transmission power,this paper explores the application effect of using z-index in evaluating the journal network transmission power.By collecting the sample data from library science,information science and documentation science journals,this paper investigates the effectiveness,scientific and advanced nature of z-index(z d-index)based on download frequency in the evaluation of journal network transmission power.z d-index has relativity with traditional journal evaluation index which shows that z d-index has relative validity in the journal evaluation.Compared with h d-index,z d-index has higher distinction degree,better sensitivity and integrity.Besides,compared with p d-index,z d-index has more observation dimensions which make up for p d-index s inability to observe data distribution.As the net-based index,z d-index possesses advantages of strong timeliness,high reader participation,anti-disturbance capacity,and degree of reflection to the journal s value and the results show that the scientific nature of evaluation index.Compared with net-based indexes such as overall downloading frequency,piece downloading frequency,h d-index and p d-index,z d-index not only grasps the whole and highlights the key points,but also goes deeply into the investigation of the distribution of the journal s downloading data.In this way,z d-index corrects the deviation on the evaluation results caused by data distribution and the results show that the evaluation index is obviously advanced.
