We investigate the automatic detection of sentences containing linguistic hedges us- ing corpus statistics and syntactic pat- terns. We take Wikipedia as an already annotated corpus using its tagged weasel words which mark sentences and phrases as non-factual. We evaluate the quality of Wikipedia as training data for hedge detec- tion, as well as shallow linguistic features.
