Abstract Purpose We study the proportion of Web of Science (WoS) citation links that are represented in the Crossref Open Citation Index (COCI), with the possible aim of using COCI in research evaluation instead of the WoS, if the level of coverage was sufficient. Design/methodology/approach We calculate the proportion on citation links where both publications have a WoS accession number and a DOI simultaneously, and where the cited publications have had at least one author from our institution, the Czech Technical University in Prague. We attempt to look up each such citation link in COCI. Findings We find that 53.7% of WoS citation links are present in the COCI. The proportion varies largely by discipline. The total figures differ significantly from 40% in the large-scale study by Van Eck, Waltman, Larivière, and Sugimoto (blog 2018, https://www.cwts.nl/blog?article=n-r2s234). Research limitations The sample does not cover all science areas uniformly; it is heavily focused on Engineering and Technology, and only some disciplines of Natural Sciences are present. However, this reflects the real scientific orientation and publication profile of our institution. Practical implications The current level of coverage is not sufficient for the WoS to be replaced by COCI for research evaluation. Originality/value The present study illustrates a COCI vs WoS comparison on the scale of a larger technical university in Central Europe.

Crossref引文能否代替Web of Science进行研究评估？公开引文的份额

摘要目的我们研究以交叉引用开放式引文索引（COCI）表示的Web of Science（WoS）引文链接的比例，如果覆盖范围足够的话，可能的目的是在研究评估中使用COCI代替WoS 。设计/方法/方法我们计算引文链接的比例，其中两个出版物同时具有WoS登记号和DOI，并且引用的出版物至少有我们机构布拉格的捷克技术大学的一位作者。我们尝试在COCI中查找每个此类引用链接。发现我们发现COCI中存在53.7％的WoS引用链接。该比例在很大程度上因学科而异。总体数字与Van Eck，Waltman，Larivière和Sugimoto进行的大规模研究的40％显着不同（博客2018，https：// www。cwts.nl/blog?article=n-r2s234）。研究局限性本样本并未统一涵盖所有科学领域。它专注于工程和技术，并且只存在自然科学的某些学科。但是，这反映了我们机构的真正科学方向和出版物概况。实际意义当前的覆盖范围不足以将COS替换为WoS进行研究评估。独创性/价值本研究说明了中欧一所规模较大的技术大学在COCI与WoS方面的比较。这反映了我们机构的真正科学方向和出版物概况。实际意义当前的覆盖范围不足以将COS替换为WoS进行研究评估。独创性/价值本研究说明了中欧一所规模较大的技术大学在COCI与WoS方面的比较。这反映了我们机构的真正科学方向和出版物概况。实际意义当前的覆盖范围不足以将COS替换为WoS进行研究评估。独创性/价值本研究说明了中欧一所规模较大的技术大学在COCI与WoS方面的比较。
