The Nature Index is a database of creator affiliations and institutional relationships. The index tracks contributions to analysis articles printed in high-quality natural-science and health-science journals, chosen primarily based on popularity by an impartial group of researchers.
The Nature Index supplies absolute and fractional counts of article publication on the institutional and nationwide degree and, as such, is an indicator of world high-quality analysis output and collaboration. Knowledge within the Nature Index are up to date recurrently, with the newest 12 months made obtainable underneath a Artistic Commons licence at natureindex.com. The database is compiled by Nature Portfolio.
Nature Index metrics
The Nature Index makes use of Depend and Share to trace analysis output. A rustic/territory or an establishment is given a Depend of 1 for every article that has at the least one creator from that nation/territory or establishment. That is the case whatever the variety of authors an article has, and it signifies that the identical article can contribute to the Depend of a number of international locations/territories or establishments.
To glean a rustic’s, territory’s, area’s or an establishment’s contribution to an article, and to make sure that they aren’t counted greater than as soon as, the Nature Index makes use of Share, a fractional depend that takes under consideration the share of authorship on every article. The entire Share obtainable per article is 1, which is shared amongst all authors underneath the belief that every contributed equally. As an example, an article with 10 authors signifies that every creator receives a Share of 0.1. For authors who’re affiliated with a couple of establishment, the creator’s Share is cut up equally between every establishment. The entire Share for an establishment is calculated by summing the Share for particular person affiliated authors. The method is comparable for international locations/territories, though difficult by the truth that some establishments have abroad labs that will likely be counted in direction of host nation/territory totals.
Adjusted Share accounts for the small annual variation within the complete variety of articles within the Nature Index journals. It’s arrived at by calculating the proportion distinction within the complete variety of articles within the Index in a given yr relative to the variety of articles in a base yr and adjusting Share values to the bottom yr ranges.
The bilateral collaboration rating (CS) between two establishments A+B is the sum of every of their Shares on the papers to which each have contributed. A bilateral collaboration may be between any two establishments or international locations/territories co-authoring at the least one article within the journals tracked by the Nature Index.
NATUREINDEX.COM
natureindex.com customers can seek for particular establishments or international locations and generate their very own reviews, ordered by Depend or Share.
Every question will return a profile web page that lists the nation or establishment’s current outputs, from which it’s potential to drill down for extra info. Articles may be displayed by journal, after which by article. Analysis outputs are organized by topic space. The pages checklist the establishment or nation’s/territory’s high collaborators, in addition to its relationship with different organizations. Customers can observe an establishment’s efficiency over time, create their very own indexes and export desk information.
This complement
The Nature Index 2024 Synthetic intelligence complement is predicated on each the Nature Index database and the Digital Science Dimensions database, overlaying the Nature Index articles printed between 1 January 2019 and 31 December 2023 in addition to the Dimensions publications throughout the identical interval. Searches utilizing key phrases and fields of analysis have been used to extract artificial-intelligence publications in Dimensions, together with journal and convention papers. Synthetic-intelligence articles within the Nature Index are these extracted publications which can be additionally within the Nature Index database.
Nature Index 2024 Synthetic intelligence
The next key phrases have been searched within the Dimensions database: ‘machine studying’, ‘synthetic intelligence’, ‘machine intelligence’, ‘machine imaginative and prescient’, ‘supervised studying’, ‘unsupervised studying’, ‘deep studying’, ‘reinforcement studying’, ‘switch studying’, ‘Bayesian studying’, ‘ensemble studying’, ‘federated studying’, ‘generative adversarial community’, ‘random forest’, ‘assist vector machine’, ‘explainable AI’, ‘pc imaginative and prescient’, ‘speech recognition’, ‘face recognition’, ‘pure language processing’, ‘autonomous car’, ‘driverless automotive’, ‘self-driving automotive’, ‘DeepVariant’, ‘Clairvoyante’, ‘WhatsHap’, ‘statistical studying idea’, ‘sentiment evaluation’, ‘emotion AI’, ‘opinion mining’, ‘neurocomputing’, ‘neural computing’, ‘neurocomputation’, ‘neural computation’, ‘neural fuzzy community’, ‘synthetic neural community’, ‘Bayesian neural community’, ‘multilayer neural community’, ‘distributed neural community’, ‘convolutional neural community’, ‘computational neural community’, ‘deep neural community’, ‘deeper neural community’, ‘fuzzy neural community’, ‘neural community mannequin’, ‘spiking neural community’, ‘unsupervised neural community’, ‘AI software’, ‘AI pushed’, ‘AI assisted’, ‘OpenAI’.
The tables on this complement present the main establishments and international locations/territories in synthetic intelligence primarily based on their complete output between 2019 and 2023, and the highest rising establishments within the area primarily based on the change of their output from 2019 to 2023. Nature Index output is measured by article Share and Dimensions output is measured by the variety of publications. There are additionally extra main establishment tables by sector primarily based on the Nature Index information.
