Predicting missing links in citation network : Kaggle competition

Edges have been deleted at random from a citation network. Our mission is to accurately reconstruct the initial network. We define a citation network as a graph where nodes are research papers and there is an edge between two nodes if one of the two papers cite the other.

615,512 labeled node pairs (1 if there is an edge between the two nodes, 0 else). One pair and label per row, as: source node ID, target node ID, and 1 or 0. The IDs match the papers in the node information file (see below).

32,648 node pairs. One pair per row, as: source node ID, target node ID.

for each paper out of 27,770, contains the paper (1) unique ID, (2) publication year (between 1993 and 2003), (3) title, (4) authors, (5) name of journal (not available for all papers), and (6) abstract. Abstracts are already in lowercase, common English stopwords have been removed, and punctuation marks have been removed except for intra-word dashes.
