  Humans express ideas, beliefs, and statements through language. The manner of
expression can carry information indicating the author's degree of confidence
in their statement. Understanding the certainty level of a claim is crucial in
areas such as medicine, finance, engineering, and many others where errors can
lead to disastrous results. In this work, we apply a joint model that leverages
words and part-of-speech tags to improve hedge detection in text and achieve a
new top score on the CoNLL-2010 Wikipedia corpus.
