Such systems are relatively easy to set up and experienced many successes: the TEES system (Björne et al., 2009;Bj[Pleaseinsertintopreamble]rne et al., 2012; Björne and Salakoski, 2013) won the BioNLP GE task in 2009 and ranked 2 nd in 2013, whereas the EVEX system won in 2013 (Van Landeghem et al., 2011;Hakala et al., 2013).
all these methods suffer from error cascading.
