相关性视角下的WoS与Scopus之比较

Comparision Between WoS and Scopus from the Perspective of Correlation

以F1000数据库中生物信息学和免疫学近2 000篇文献为样本,多角度探讨WoS与Scopus数据库的优劣,其中包括两个数据库中被引频次的相关性、与F1000因子的相关性、主要评价指标数值及排序的相关性、历年被引累积量与被引总量相关性、多维空间感知图下的指标间相关性。结论指出:虽然各项指标源于WoS与Scopus不同的数据库,但是就被引频次及与F1000因子关系而言,两库具有较好的一致性;两库的主要评价指标,无论是数值抑或是排序,均体现出高度相关。上述结果可为科研评价中两个数据库的替代性和选择性提供借鉴,同时为定位在开源Scopus系统的利用提供有力依据。

Based on a sample of nearly 2000 documents from bioinformatics and immunology in F1000 database , the paper makes a comparision between WoS and Scopus. For this, the correlation analysis is used for the study of cited frequency, the number and rank of indexes, the accumulated number over the years and the total from two databases. Beside these, MDS is proceeded. Results show that although those indicators are calculated with different methods and even use different databases, they are strongly correlated with the WoS IF and among each other. These findings corroborate results published by several papers and show the feasibility of using free alternatives to the Web of Science for evaluating scientific journals.
