In this paper, we examine to which degree behavioral
measures can be used to predict personality. Personality is
one factor that dictates people’s propensity to trust and their
relationships with others. In previous work, we have shown that
personality can be predicted relatively accurately by analyzing
social media profiles. We demonstrated this using public data
from facebook profiles and text from Twitter streams. As social
situations are crucial in the formation of one’s personality, one’s
social behavior could be a strong indicator of her personality.
Given most users of social media sites typically have a large
number of friends and followers, considering only these aspects
may not provide an accurate picture of personality. To overcome
this problem, we develop a set of measures based on one’s
behavior towards her friends and followers. We introduce a
number of measures that are based on the intensity and number
of social interactions one has with friends along a number of
dimensions such as reciprocity and priority. We analyze these
features along with a set of features based on the textual analysis
of the messages sent by the users. We show that behavioral
features are very useful in determining personality and perform
