(2009), we use the BIO-cue labels for all tokens in a sentence to predict whether a token is the first one of a hedge cue (B-cue), inside a hedge cue (I-cue), or outside of a hedge cue (O-cue).
our experiments are conducted on two training data sets: one is the abstracts and full articles from BioScope (biomedical domain) corpus (Vincze et al., 2008) 1 , the other one is paragraphs from Wikipedia possibly containing weasel information.
