Oshri & Fogel-Dror.'A matter of identity: Measuring agenda setting power in a fragmented parliament.' Close to submission. Presented at EPSA 2017. This paper assesses legislators' discursive interactions in order to examine the agenda-setting power of groups in the European Parliament. First, we map the discourse space in the EP by automatically topic-modeling the discourse in its 6th session. Next, we extract the net effect of each group on the discourse, showing how the political-discourse space in the EP is divided according to groups, with different groups controlling different agendas. Finally, we demonstrate that, although the EP is organized along transnational lines, it enables groups with different political affiliations to make their voices heard, both nationally and transnationally. Whose voice is the loudest depends on the issue at hand.
