Making the CWTS Leiden ranking more transparent
The CWTS Leiden Ranking aims to provide a responsible alternative to major university rankings such as Shanghai (ARWU), THE, and QS. However, due to the proprietary nature of the data used in the Leiden Ranking, the transparency of the ranking has always been limited. In this talk I will discuss the development of the Open Edition of the Leiden Ranking, a fully transparent edition of the ranking based on data from OpenAlex. I will also reflect on the broader movement toward more responsible ways of dealing with university rankings.
