Continuing the tradition of previous years, ICWSM 2009 is making a new dataset available to researchers. The ICWSM-2009 dataset contains 44 million blog posts made between August 1st and October 1st, 2008. The organizers of ICWSM-2009 especially encourage submissions that make use of this data. A special "data challenge workshop" will be held on May 20th (the last day of ICWSM-2009) for shorter, more focused, and/or late-breaking papers that use this ICWSM-2009 dataset; the deadline for data challenge workshop papers is March 1st.
