Abstract

The IDA/CCS summarization system, CLASSY, underwent significant change for this year’sDUC. 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.
