Abstract

This communication aims to analyse the information that a large set of free-access databases (i.e., Crossref, Dimensions, Microsoft Academic, OpenAlex, Scilit, Semantic Scholar, The Lens) provides about indexed publications in their databases. Using a random sample of 116k publications from Crossref, each database was queried to retrieve the same document list with the purpose of comparing the metadata of their publications. The results show that the completeness degree is different between databases and that the search engines show more problems to extract abstracts and assign document typologies. Dimensions is the product that obtain the highest completeness percentages in abstracts, open access documents, bibliographic data and document types.

Impact byBIP!

	citations This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).	1
	popularity This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.	Average
	influence This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).	Average
	impulse This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation network.	Average
