State-of-theart machine learning and rule-based SBD systems achieve an error rate of 0.8 -- 1.5 % measured on the Brown corpus and the WSJ corpus . The best performance on the WSJ corpus was achieved by a combination of the SATZ system ( Palmer and Hearst 1997 ) with the Alembic system ( Aberdeen et al. 1995 ) : a 0.5 % error rate . The best performance on the Brown corpus , a 0.2 % error rate , was reported by Riley ( 1989 ) , who trained a decision tree classifier on a 25-million-word corpus .
