Hi everyone, Thank you all for your replies, we really appreciate your cooperation. Below is a summary of the tools and data sets recommended by Torsten, Andrew, paolo, and emijrp. We would also like to know if there is any existing Wikipedia page that includes such a list so we can add to it. Otherwise, where do you suggest adding this list so it is noticeable and useful for the community? http://code.google.com/p/jwpl/ http://wikipedia-miner.sourceforge.net/ http://code.google.com/p/wikokit/ /*Wiktionary parser and visual interface */ https://github.com/phauly/wiki-network/ /*Python scripts for parsing Wikipedia dumps with different goals*/ http://www.gnuband.org/2011/04/19/wikipedia_datasets_released/ /*datasets of network extracted from User Talk pages*/ http://code.google.com/p/wikiteam/ http://code.google.com/p/wikiteam/downloads/list?can=1 http://www.research.ibm.com/visual/projects/history_flow/ http://meta.wikimedia.org/wiki/WikiXRay http://statmediawiki.forja.rediris.es/index_en.html Best regards, Mohamad Mehdi
