Two changes made processing simpler and faster: 1) we eliminated the use of a POS (part of speech) tagger for sentence splitting and to assist sentence trimming, and 2) we simplified the scoring of sentences for inclusion in the summary by introducing a new “approximate oracle” score. An additional change introduced a modest amount of extra computation: we ordered sentences in the summary using a new Traveling Salesperson (TSP) formulation. These changes improved ROUGE scores on the DUC 2005 data from last year and gave strong performance in the DUC 2006 competition. %B DUC 06 Conference ProceedingsDUC 06 Conference Proceedings %I U.S. National Inst. of Standards and Technology %8 2006/// %G eng %U \tt http://duc.nist.gov/
