For our experiments, we use the standard TAC data sets 8 , which have been used in the NIST competitions and in other summarization studies.
we used the TAC 2010 data set for creating the guided compression corpus and training the SVR pre-selection model, the TAC 2009 data set as development set for parameter tuning, and the TAC 2008 and 2011 data sets as the test set for reporting the final summarization results.
