2009 Proceedings of the 15th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '09  
Our extensive experiments show that social networks and the web graph exhibit vastly different compressibility characteristics.  ...  Boldi and Vigna (WWW 2004), showed that Web graphs can be compressed down to three bits of storage per edge; we study the compressibility of social networks where again adjacency queries are a fundamental  ...  Our main findings are: social networks appear far less compressible than Web graphs yet closer to host graphs and exploiting link reciprocity in social networks can vastly help its compression.  ...

Neighbor query friendly compression of social networks

Hossein Maserrat, Jian Pei
2010 Proceedings of the 16th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '10  
Compressing social networks can substantially facilitate mining and advanced analysis of large social networks.  ...  Arguably, neighbor queries, which search for all neighbors of a query vertex, are the most essential operations on social networks.  ...  Real life social networks are often large and sparse. Thus, the Eulerian data structure is capable of compressing social networks.  ...

One of the most relevant characteristics of social networks is community structure, in which network nodes are joined together in densely connected groups between which there are only sparser links.  ...  In this paper, we propose a novel approach, called CS-ComDet, to efficiently detect the inter-community links based on a newly emerged paradigm in sparse signal recovery, called compressive sensing.  ...  To the best of our knowledge, there is no previous work on intercommunity detection in social networks using compressive sensing.  ...
