In this paper we address the issue of how users’ personality affects the way people interact and communicate in Facebook. Due to the strict privacy policy and the lack of a public timeline in Facebook, we automatically sampled data from the timeline of one “access user”. Exploiting Facebook’s graph APIs, we collected a corpus of about 1100 ego-networks of Italian users (about 5200 posts) and the users that commented their posts. We considered the communicative exchanges, rather than friendships, as a network. We annotated users’ personality by means of our personality recognition system, that makes use of correlations between written text and the Big5 personality traits, namely: extroversion, emotional stability, agreeableness, conscientiousness, openness. We tested the performance of the system on a small gold standard test set, containing statuses of 23 Facebook users who took the Big5 personality test. Results showed that the system has a average f-measure of .628 (computed over all the five personality traits), which is in line with the state of the art in personality recognition from text. The analysis of the network, that has a average path length of 6.635 and a diameter of 14, showed that open-minded users have the highest number of interactions (highest edge weight values) and tend to be influential (they have the highest degree centrality scores), while users with low agreeableness tend to participate in many conversations.

Abstract

In this paper we address the issue of how users’ personality affects the way people interact and communicate in Facebook. Due to the strict privacy policy and the lack of a public timeline in Facebook, we automatically sampled data from the timeline of one “access user”. Exploiting Facebook’s graph APIs, we collected a corpus of about 1100 ego-networks of Italian users (about 5200 posts) and the users that commented their posts. We considered the communicative exchanges, rather than friendships, as a network. We annotated users’ personality by means of our personality recognition system, that makes use of correlations between written text and the Big5 personality traits, namely: extroversion, emotional stability, agreeableness, conscientiousness, openness. We tested the performance of the system on a small gold standard test set, containing statuses of 23 Facebook users who took the Big5 personality test. Results showed that the system has a average f-measure of .628 (computed over all the five personality traits), which is in line with the state of the art in personality recognition from text. The analysis of the network, that has a average path length of 6.635 and a diameter of 14, showed that open-minded users have the highest number of interactions (highest edge weight values) and tend to be influential (they have the highest degree centrality scores), while users with low agreeableness tend to participate in many conversations.
