"Text Mining for Assessment of Writing and Social Positioning," Carolyn Penstein Rosé, associate professor, Language Technologies Institute and HCI Institute, Carnegie Mellon University, Pittsburgh, Pennsylvania.

Computational models of discourse reveal evidence of cognitive and social processes and competencies that are valuable both for assessment and for triggering real time support for learning. In this talk I will offer a brief overview of the field of text mining as it is represented in application areas such as assessment of writing and of social positioning in collaborative discourse. Then I will zoom in on the topic of analysis of role taking behavior in collaborative groups where computational models of social interaction in textual form reveal layer upon layer of insight about student orientation towards one another as well as towards their joint endeavors. When we observe successful and unsuccessful teams, we see unexpected behavior profiles, ones that do not necessarily align with assigned roles as well as ones that do not necessarily align with expectations of effective role-taking. In this talk I will introduce a novel rolebased-behavior modeling approach that enables identification of behavior profiles that are associated with specific success measures. This enables dynamic support for student reflection on their
