From Words to Senses: A Case Study of Subjectivity Recognition

We determine the subjectivity of word senses. To avoid costly annotation, we evaluate how useful existing resources established in opinion mining are for this task. We show that results achieved with existing resources that are not tailored towards word sense subjectivity classification can rival results achieved with supervision on a manually annotated training set. However, results with different resources vary substantially and are dependent on the different definitions of subjectivity used in the establishment of the resources.
