Finding hedges by chasing weasels: Hedge detection using Wikipedia tags and shallow linguistic features is a 2009 conference paper written in English by Ganter V., Strube M. and published in ACL-IJCNLP 2009 - Joint Conf. of the 47th Annual Meeting of the Association for Computational Linguistics and 4th Int.

[edit] Abstract

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.
