What is the best combination of features from Facebook API I can have to accurately predict user personality? Many of the researchers have been using textual features (LIWC) and others combined it with some extra post specific features such as (#like,#posts,#events...etc) and others just asked participants to fill up an online survey that captures their Big 5 personality traits.
Can you recommend any features to be extracted from social networks platforms that facilitate the process of predicting personality?
