To measure the usefulness of discourse relations for the summarization of informal texts, we have tested the effect of each relation with four different summarizers: BlogSum<cite> (Mithun, 2012)</cite> , MEAD<cite> (Radev et al., 2004)</cite> , the best scoring system at TAC 2008 5 and the best scoring system at DUC 2007 6 . Finally the most appropriate schema is selected based on a given question type; and candidate sentences fill particular slots in the selected schema based on which discourse relations they contain in order to create the final summary (details of BlogSum can be found in<cite> (Mithun, 2012)</cite> ).
