scientific collaboration hypernetworks

PubMed was used as the data source to collect the literatures in the field of stem cells published from 2016 to 2020 with the keyword "stem cell". Excluding the literatures without cooperative relationship, 38453 effective literatures were obtained. In the process of document data processing, the author's full name and research institution were used to solve the problem of author's duplicate name. A total of 250714 authors, 2762 binary cooperative relationships and 32876 multiple cooperative relationships were obtained; Then, the author is taken as the node, the cooperation relationship as the super edge, and the text information such as the title and abstract of the author's literature as the attribute of the node to construct the scientific research cooperation super network; Finally, in order to comprehensively evaluate the performance of the recommendation algorithm, three subnetworks of different sizes, hypernet-1, hypernet-2 and hypernet-3, are extracted from the scientific research cooperation hypernetwork. Among them, hypernet-k means that at least one author node in each super edge of the super network has a superdegree greater than k.
