ImpactStory is the firstopen source, web-based tool released by OurResearch. It providesaltmetrics to help researchers measure the impacts of their research outputs includingjournal articles,blog posts, datasets, and software.[9] This aims to change the focus of the scholarly reward system to value and encourage web-native scholarship.
It provides context to its metrics so that they are meaningful without knowledge of the specific dataset: for example, instead of letting the reader guess whether having fiveforks onGitHub is common, ImpactStory would tell that the repository is in the 95th percentile of all GitHub repositories created that year.[10]
The metrics provided by ImpactStory can be used by researchers who want to know how many times their work has been downloaded and shared,[11] and alsoresearch funders who are interested in the impact of research beyond only considering citations to journal articles.
Unpaywall, begun as an interface foroaDOI.org,[12][13] is abrowser extension[14] which finds legal free versions of (paywalled) scholarly articles.[15] In July 2018, Unpaywall was reported to provide free access to 20 million articles,[1] which accounts for about 47% of the articles that people search for with Unpaywall.[16] As of 2024, Unpaywall claims to provide access to 49 million free articles.[17] It further states that "Unpaywall users read 52% of research papers for free".[18] In June 2017, it was integrated intoWeb of Science, and in July 2018,Elsevier announced plans the same month to integrate the service into theScopus search engine.[1]
Unsub,[21] previously Unpaywall Journals,[22] was launched in 2019[23] as adata analysis tool for libraries to estimate the actual cost and value of their subscriptions.[24]
Unpaywall Journals was used in 2020 by theSUNY Libraries Consortium to assist in the cancellation of theirbig deal withElsevier, which was replaced by a subscription to 248 titles,[30] allowing expected savings of 50–70% over the baseline, or 5 to 7 million dollars per year.[31]
OpenAlex[32] is an open catalog of scholarly papers, authors, institutions, and more. OpenAlex launched in January 2022 with a free API and data snapshot.[33] The purpose of OpenAlex is to catalog publication sources, author information, and research topics. It also shows connections between these data points to provide a comprehensive, interlinked view of the global research system.[34] It is considered an alternative to theMicrosoft Academic Graph, which retired on December 31, 2021.[35][36]
OpenAlex contains extensive metadata across scientific works, authors, publication venues, institutions, and concepts. Specifically, it includes metadata for 209 million works such as journal articles and books; 13 million authors with disambiguated identities; metadata for 124,000 venues that host works, including journals and online repositories; metadata for 109,000 institutions; and 65,000 concepts fromWikidata, which are algorithmically linked to works using an automated hierarchical multi-tag classifier.[37]
