We investigate the automatic detection of sentences containing linguistic hedges using corpus statistics and syntactic patterns. 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 detection, as well as shallow linguistic features.
REF proposed an approach for the automatic detection of sentences containing uncertainty based on Wikipedia weasel tags and syntactic patterns.
