scientific collaboration hypernetworks

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.
