JWNMF

This is an Unofficial implementation of method proposed by Tang in [1].

Sample Data

In this repository, we've placed a test data which is a sythensized graph generated using method proposed in [2] and simulated cascades of posts exchanged between social network nodes. Underlying graph in this data has 100 nodes and we've simulated 200 i.i.d. cascades on that. To use this to for testing proposed method in [1], we've randomly deleted some links and cascade participations.

How to run

Convert data

python converter/convert.py -d <dataset>

Run Code
