Search has long been revolutionized by knowledge-graph-powered services such as the Amazon Marketplace in e-commerce, or Open Street Maps in the cartography and navigation services domains, to name just two examples. Inspired by such knowledge graph (KG) success stories in the general domain, such technology is now being realized over scholarly knowledge as well.

In recent years, bibliometric databases have substantially improved the consistency and quality of the metadata extracted from publications, particularly the author-affiliations linkages from scientific publications. Furthermore, author-name disambiguation algorithms have been implemented for most large bibliometric databases, such as Web of Science, Scopus, and Dimensions.

In most research fields, journals play a dominant role in the scholarly communication system. However, the availability of systematic information on the policies and practices of journals, for instance with respect to peer review and open access publishing, is surprisingly limited and scattered.

Since 2017 we have been developing a new approach to research evaluation, which we call Evaluative Inquiry (EI). In a series of blog posts, we discuss the four principles of EI, based on our experiences in projects with the Protestant Theological University and with the University for Humanistics.

The shift in R&D goals towards the SDGs is driving demand for new S&T indicators… The shift in Science & Technology policy from a focus on research quality (or ‘excellence’) towards societal impact has led to a demand for new Science & Technology indicators that capture the contributions of research to society, in particular those aligned with SDGs.

I would like to tell you about a book that changed my life, but I don’t want to spoil it yet by revealing the title. You see, since I was young, I had always anguished about career choices. I imagined that I would be forced to put hours into something I hate, and I would arrive home after work hating myself too.

This post is based on the following manuscript, currently under review: Tiokhin, L., Panchanathan, K., Lakens, D., Vazire, S., Morgan, T., & Zollman, K. (Preprint). Honest signaling in academic publishing, and is also published in the author's blog author's blog). “An article…is not the scholarship itself, it is merely advertising of the scholarship.” (Buckheit &

In a series of blog posts, we want to introduce the four principles of a new CWTS approach to research evaluation. Since 2017 we have been developing this approach in the context of several projects mainly assisting others with putting together the self-evaluation document of the Standard Evaluation Protocol.

The World Health Organization has declared a COVID-19 ‘infodemic’: an overabundance of information which is often mixed with rumours and misinformation. In light of this, CWTS researchers Giovanni Colavizza and Karlijn Roex are conducting a study in which they investigate how science is communicated during the coronavirus pandemic.

“What do you do for work?” is a common conversation starter at social gatherings. For doctors or teachers, this is easier to answer, but for members of the A-TEAM this is a question that requires a lengthy explanation. The short answer would be that we unify organizations in a database, but this does not cover all our work.

Today CWTS is releasing the 2020 edition of the CWTS Leiden Ranking. As always, the release of the ranking requires a major effort involving contributions from a large number of colleagues at our center. This year, the COVID-19 crisis, combined with a major update of the internal data infrastructure at CWTS, created additional challenges, which has unfortunately led to a delay of almost two months in the release of the ranking.
