Untangling citation networks

摘要

The pattern of citation links between articles permits a placement in a space of points representing these articles. Using the rule that articles are placed at the centroid of the articles to which they are linked, pictures can be drawn revealing key papers and their descendants. This simple rule for placing papers by their citation pattern may also be used to scale other citation-based data. The example used in this paper is the placement of overlapping groups of articles linked by shared articles.
