COLLAB Dataset

COLLAB is a scientific collaboration dataset. A graph corresponds to a researcher’s ego network, i.e., the researcher and its collaborators are nodes and an edge indicates collaboration between two researchers. A researcher’s ego network has three possible labels, i.e., High Energy Physics, Condensed Matter Physics, and Astro Physics, which are the fields that the researcher belongs to. The dataset has 5,000 graphs and each graph has label 0, 1, or 2.

COLLAB为一项科学合作数据集。其中，每张图对应一位研究者的自我网络，即研究者及其合作者构成节点，而边则表示两位研究者之间的合作关系。研究者的自我网络具有三种可能的标签，即高能物理、凝聚态物理和天体物理，这些即为研究者所属的领域。该数据集包含5,000个图，每个图均标注为0、1或2。
