    The Subjectivity Sense Annotations used in (Wiebe and Mihalcea, 2006) and (Gyamfi et al., 2009) are both available for download. Both annotation efforts follow the annotation schema described in (Wiebe and Mihalcea 2006) and rely on WordNet 2.0 as the sense inventory. Further information on the data can be found in the README of the archive you download.
