  Instead of studying the properties of social relationship from an objective
view, in this paper, we focus on individuals' subjective and asymmetric
opinions on their interrelationships. Inspired by the theories from
sociolinguistics, we investigate two individuals' opinions on their
interrelationship with their interactive language features. Eliminating the
difference of personal language style, we clarify that the asymmetry of
interactive language feature values can indicate individuals' asymmetric
opinions on their interrelationship. We also discuss how the degree of
opinions' asymmetry is related to the individuals' personality traits.
Furthermore, to measure the individuals' asymmetric opinions on
interrelationship concretely, we develop a novel model synthetizing interactive
language and social network features. The experimental results with Enron email
dataset provide multiple evidences of the asymmetric opinions on
interrelationship, and also verify the effectiveness of the proposed model in
measuring the degree of opinions' asymmetry.
