Weight Edge Sum Projection Scheme

Description

This weight scheme sums the deleted node adjacent edges when re-wired in the projection graph. For most cases, this is the commonly used approach in the literature.

Usage

weight_scheme_sum_edges(projected_graph)

Arguments

projected_graph

A semi-processed bipartite projection network resulting

Details

For example assume author A changes file1 three times, and author B changes file1 one time. A projection which returns a author-author network using this function would return, assuming this being the entire collaboration graph, that author A and author B have a connection of 3 + 1 = 4.

Suppose now also that the entire collaboration graph contains another file2 such that author A and author B modified 2 and 3 times respectively. Hence in the projection step, this would further contribute a 2 + 3 = 5 weight to authors A and B. In this graph, where file1 and file2 are present, the final weight for authors A and B would thus be (3 + 1) + (2 + 3) = 9.
