Open Academic Graph (OAG) is a large knowledge graph unifying two billion-scale academic graphs:\u00a0Microsoft Academic Graph (opens in new tab)<\/span><\/a>\u00a0(MAG) and\u00a0AMiner (opens in new tab)<\/span><\/a>. In mid 2017, we published OAG v1, which contains 166,192,182 papers from MAG and 154,771,162 papers from AMiner (see below) and generated 64,639,608 linking (matching) relations between the two graphs. This time, in OAG v2, author, venue and newer publication data and the corresponding matchings are available.<\/p>\n

Overview of OAG v2<\/h2>\n

The statistics of OAG v2 is listed as the three tables below. The two large graphs are both evolving and we take MAG November 2018 snapshot and AMiner July 2018 or January 2019 snapshot for this version.<\/p>\n
