A Friendship Generation Model Considering Information Access Scope

Abstract

Humans belong to various social groups. Friendship is one of the factors composing social groups. It is important to understand the characteristics of generation and changing friendship networks in order to understand social groups. Previous studies have proposed models for observing friendship transitions and simulated actual friendship networks. There are friendship generation models based on rational and structural choices. Information Access Scope shows a scope that can know hobbies and preferences about others, and related to rational choice. Thereby, the Information Access Scope affects friendship generation. However, previous studies have not examined which Information Access Scope is suitable for a friendship generation model. In this study, we propose a friendship generation model considering Information Access Scope and simulate multiple patterns of Information Access Scope with reference to previous studies. We compared those simulated friendships with actual friendships. As a result, we were able to find an Information Access Scope suitable for the actual friendship.
