In this paper we investigate how to auto- matically determine if two document col- lections are written from different per- spectives. By perspectives we mean a point of view, for example, from the per- spective of Democrats or Republicans. We propose a test of different perspectives based on distribution divergence between the statistical models of two collections. Experimental results show that the test can successfully distinguish document collec- tions of different perspectives from other types of collections.
