openalex_cocitations — Co-citations of highly cited papers in five fields (OpenAlex, 2024)
- Description
Bipartite networks of highly cited papers and the sets of them that are cited together, in five fields of research, built by Nakajima et al. from the OpenAlex snapshot of 27 September 2024, as distributed by XGI-data:
biochem: Biochemistry, Genetics and Molecular Biology;cs: Computer Science;math: Mathematics;neuro: Neuroscience;physics: Physics and Astronomy.
In each field, the papers of each subfield were ranked by their numbers of citations, and the top papers that account for 10% of the cumulative citations of the subfield were selected (at least 100 papers per subfield). For each other paper of OpenAlex, the set of selected papers it cites was determined; each set of at least two papers that is cited by at least 3 papers is a co-citation set, connected to its papers. The sets cited by fewer papers, and the numbers of papers citing each set, are not included in the data.
The networks have the following properties:
- (Node)
is_cocitation: whether the node is a co-citation set (otherwise a paper). - (Node)
openalex_id(papers): the OpenAlex identifier of the paper (e.g.W2010634640, seehttps://openalex.org/<id>). - (Node)
title(papers): the title of the paper (in lower case). - (Node)
date(papers): the publication date (YYYY-MM-DD). - (Node)
year(papers): the publication year. - (Node)
topic,subfield,field,domain(papers): the primary topic of the paper in OpenAlex and its subfield, field and domain. - (Node)
cited_by_count(papers): the number of citations of the paper in OpenAlex.
