Partition based Graph Compression

Meera Dhabu, Dr. P., Siyaram Vishwakarma
2013 International Journal of Advanced Computer Science and Applications  
A graph containing millions of nodes and billions of edges can be of size in TBs.

Visualization of Mined Pattern and Its Human Aspects [article]

Ratnesh Kumar Jain, Dr. Suresh Jain, Dr. R. S. Kasana
2009 arXiv   pre-print
Researchers got success in mining the Web usage data effectively and efficiently. But representation of the mined patterns is often not in a form suitable for direct human consumption.  ...  Hence mechanisms and tools that can represent mined patterns in easily understandable format are utilized. Different techniques are used for pattern analysis, one of them is visualization.  ...  Examples of task-specific props for visualization are: a physical model head and clip plane that aid interaction with volumetric brain data [38] and the "Cubic Mouse," a 3D input device for volume data  ...
