Comparison of two local social media services in Finland and China by social network analysis

Social network analysis has been widely used in characterising user behaviours, social relationships, network evolution and service adoption of social media. However, previous research mostly focused on the famous global large scale social media such as Facebook, Wikipedia and Twitter. Comparatively, little research has been done for local social media. In this paper, we compare two similar campus-based social media for exchanging goods and services by social network analysis. We also explore the correlation between different social relationships (e.g., the friend relation and exchanging relation) and different user behaviours (e.g., the requesting and offering) by quadratic assignment procedure (QAP) and Pearson correlation analysis methods. Finally, we discuss our findings and future work.
