This article presents an affective based sensemaking system for grouping and suggesting stories created by the users about the items of a museum. By relying on the TCL commonsense reasoning framework1, the system exploits the spatial structure of the Plutchik's wheel of emotions to organize the stories according to their extracted emotions. The process of emotion extraction, reasoning and suggestion is triggered by an app, called GAMGame, and integrated with the sensemaking engine. Following the framework of Citizen Curation, the system allows classifying and suggesting stories encompassing cultural items able to evoke not only the very same emotions of already experienced or preferred museum objects, but also novel items sharing different emotional stances and, therefore, able to break the filter bubble effect and open the users' view towards more inclusive and empathy-based interpretations of cultural content. The system has been designed tested, in the context of the H2020EU SPICE project (Social cohesion, Participation, and Inclusion through Cultural Engagement), in cooperation the community of the d/Deaf and on the collection of the Gallery of Modern Art (GAM) in Turin. We describe the user centered design process of the web app and of its components and we report the results concerning the effectiveness of the of the diversity seeking, affective driven, recommendations of stories.
