While subjectivity related research in other languages has increased, most of the work focuses on single languages. This paper explores the integration of features originating from multiple languages into a machine learning approach to subjectiv- ity analysis, and aims to show that this enriched feature set provides for more ef- fective modeling for the source as well as the target languages. We show not only that we are able to achieve over 75% macro accuracy in all of the six lan- guages we experiment with, but also that by using features drawn from multiple languages we can construct high-precision meta-classifiers with a precision of over 83%.
