This example workflow shows how leader/follower analysis can be performed on social media data using the KNIME Network Analysis plugin.
It uses data from the Slashdot homepage which is provided by Fundación Barcelona Media4 (http://caw2.barcelonamedia.org/node/25 ). A copy of the data can be download from here. The original subset contains about 140,000 comments to 496 articles about politics from a total of about 24,000 users. To allow the example to run on any machine with 2G of memory, we have subset the data around one particular topic area ("interviews") to show the techniques.
The full example along with an explanation on text mining, combined with Network mining, is available in the white paper section.
