摘要: | 社群網路如Facebook、Google+、Twitter,對使用者的互動模式產生極大的影響,角色分析可協助我們了解使用者的互動模式,但前人所提出的方法較著重於結構分析。就我們所知,目前並沒有方法使用內涵式特徵與行為特徵分析社群網路的角色,也沒有方法探討角色轉換的樣式。因此,在本篇論文中,我們提出一個內涵式的方法分析社群網路中的角色與角色轉換的樣式,我們的方法不須事先定義角色型態就能找出所有的角色,且允許使用者扮演多重角色。我們的方法可更有彈性地分析社群網路中的角色與角色轉換的樣式。實驗結果顯示我們所提出來的方法能有效地找出在不同社群中不同的內涵式行為角色,並可以找出未知的新角色,也可以找出有意義的角色轉換樣式。這些結果可協助我們更了解社群網路的發展以及未來趨勢,也可協助我們研擬更有效的管理策略。 Social networks such as Facebook, Google+, and Twitter have made a significant impact on the interactions among users. Role analysis helps us to characterize users’ interactions on a social network. However, previously proposed methods are mainly based on structural analysis of social networks rather than content-based behavior analysis. To the best of our knowledge, there is no method using content-based behavioral features extracted from user-generated content and behavior patterns to identify users’ roles and to explore role change patterns in social networks. Therefore, in this thesis, we propose a content-based method to identify users’ roles and find the role change patterns in a social network. The proposed method doesn’t need to define role types in advance and allow a user to play multiple roles on a social network. Our method provides a more general and flexible way to perform role analyses in social networks. The experimental results show that the proposed method can find various roles in a social network and additional roles that haven’t been previously aware of. It can also discover some interesting role change patterns in different groups. The results may help us better understand the trends and future growth of the social network, and formulate more effective management strategies. |
