We use pagerank algorithm on the global citation network to find the most important and influential articles within our graph. The substantive idea is as follows.
228 explain when a document d i cites a document d j we can show this by an arrow going from the node representing d i to the document representing d j.

A pdf poster of the co citation graph is also available. Our dataset is the paper citation network known as cora where graph nodes represent research papers and edges represent citation relationships between the papers.
