Detecting highly overlapping communities with Model-based Overlapping Seed Expansion

McDaid, Aaron ; Hurley, Neil J. (IEEE Computer Society, 2010-08)

As research into community finding in social networks progresses, there is a need for algorithms capable of detecting overlapping community structure. Many algorithms have been proposed in recent years that are capable of ...
Detecting highly overlapping community structure by greedy clique expansion

Lee, Conrad ; McDaid, Aaron ; Reid, Fergal ; Hurley, Neil J. (2010-07-25)

In complex networks it is common for each node to belong to several communities, implying a highly overlapping community structure. Recent advances in benchmarking indicate that existing community assignment algorithms ...
What have the neighbours ever done for us? A collaborative filtering perspective

Rafter, Rachael ; O'Mahony, Michael P. ; Hurley, Neil J. ; Smyth, Barry (Springer, 2009-06)

Collaborative filtering (CF) techniques have proved to be a powerful and popular component of modern recommender systems. Common approaches such as user-based and item-based methods generate predictions from the past ...
