Cross-domain personality prediction

In this study, we investigate the use of social media content as a domain to learn personality trait impressions, particularly extraversion. Our aim is to transfer the knowledge that can be extracted from conversational videos in video blogging sites to small group settings to predict the extraversion trait with nonverbal cues. We use YouTube data containing personality impression scores of 442 people as the source domain and a small-group meeting data from a total of 102 people as our target domain. Our results show that, for the extraversion trait, by using user-created video blogs, as part of the training data, and a small amount of adaptation data from the target domain, we are able to achieve higher prediction accuracies than using only the data recorded in small group settings.
